How To Reinstall Trial Software After The Free Trial Has Ended

One of the most common models of software sales these days is the use of the free trial. A software publisher will release a version of their program that doesn’t cost any money, but which has some substantial limitations which make the trial version significantly less useful than the paid version. There are two basic approaches to this: either offer basic features only or release the full program with a time limit that only allows the use of the trial for a fixed period of time. It is this second type of trial that we are addressing today.

Time-limited trials are much more effective at generating sales than are crippleware offerings. A program that has been hamstrung and had features cut out is not going to sell a customer on the full product – they’ve never seen the full product. Imposing a fixed time limit of 7, 14, or 30 days and letting customers experience the full program is more popular. This gives users the full experience of the software soo they can make a much more informed buying decision.

However, sometimes the trial period simply isn’t long enough and you need more time. In this article, I will show you several techniques for reinstalling trial software after the trial has ended. Note that the intention of this article is not to allow you to continue using the software indefinitely; that would be unethical. Use these techniques only to evaluate software, not to steal it.

How Do I Reinstall Software?

There are a number of different techniques that will allow you to reinstall software. Some application time trials run on the honor system – if you reinstall the program, the trial will run again. However, it is far more common for applications to attempt to detect and block cheating behaviors. Some leave a file or file or marker in the registry or in Program Data (Windows) telling the software how long it has to live. Other programs will track the date internally or use more sophisticated methods of enforcing trial periods. You can fool some of them, but you won’t be able to fool all of them.

Below are just some of the ways you can reinstall trial software after the free trial has ended. Not all methods will work in all circumstances, as different developers use varying methods to track trials. You will have to experiment with each to find what works for you. However, regardless of what method you use, the first thing to do is to copy your data files – the work you’ve done with the program – to a separate drive (perhaps a USB flash drive) so that your work will still be available.

Use An Installation Monitor To Completely Remove Trial Software

An installation monitor is a piece of software that exactly records every action taken by a setup or install program – every file transferred, every registry entry changed or created, every checkpoint created, and every icon installed. By using an installation monitor when you install a free trial, you can get an exact catalog of what it installs. When the trial ends, you can delete every trace of that program and reinstall it, as there will be no markers left behind to tell it you’ve had the free trial before. (Ordinary uninstall programs, provided by the software manufacturer, leave traces all over your computer, whether through sloppiness or design.)

Mirekusoft Install Monitor is one install monitor that you can use to perform this function. It has the advantage of being free, and it tracks everything a program installs and the locations where the files are installed. You can then forensically uninstall or delete every file once you uninstall the trial, which should allow you to reinstall trial software after the free trial has ended.

Use A File Uninstaller

The uninstaller that comes with your software is usually pretty sloppy. Nobody normally needs an uninstaller to get every last file, and nobody ever made a software purchase on the basis of how well its uninstall program worked. So predictably, uninstallers will often miss or ignore entries in the registry and on your hard drive. All the big files will be gone, and your computer will work normally, but there will be plenty of breadcrumbs left for a new trial install to detect that it’s not exploring virgin territory and refuse to install.

Using a third-party uninstaller such as Revo Uninstaller or IObit Uninstaller removes every file from everywhere. If the trial program leaves a certificate file or other resource to prevent reinstallation, these apps should find and delete it.

How To Remove Trial Version Software From Registry By Backing Up And Restoring The Windows Registry

The Windows registry is an enormous database of stored values describing just about every aspect of every piece of software and hardware on your machine. Many programs will leave traces of themselves in the registry, even if you use the included uninstaller. Even a file uninstaller might not get every registry entry, particularly if the setup and uninstall programs were designed to leave a registry entry hidden somewhere to prevent double-runs of the trial software.

However, this is relatively easy to defeat. All you have to do is take a snapshot of your Windows Registry before you install the trial for the first time. Then install and use the trial, and when the time period runs out, uninstall it, then restore the Registry to the saved values it had before the trial. However, note that this has the potential of getting your PC into a confused state, as any other changes that other programs have logged to the Registry in the meantime will also be lost.

Here’s how to backup and restore your registry.

  1. Type ‘regedit’ into the Windows search bar.
  2. Select File in the new registry window and Export.
  3. Select a safe place to keep the copy.
  4. Install the software and allow the trial to expire.
  5. Uninstall the software.
  6. Type ‘regedit’ into the Windows search bar.
  7. Select File in the new registry window and Import.
  8. Select your copy and select OK.

If the software uses a registry key to track trial installations, then this should work around that. (It’s a good idea to clean up your registry after fooling around with it – we’ve got a great guide to Windows 10 registry cleaners for you.)


Sandboxing is another useful way to trial new software, as it creates a secure location to install the program within. That program will work normally, but it will not be able to affect your computer, and thus it won’t be able to leave any lingering files behind after it’s uninstalled. It is a great way to use software, and it is especially useful when you’re trialing new programs.

One of the best-known sandbox programs is Sandboxie. Not only is it free, it is also very good at what it does. If you install your program within the sandbox, you should then be able to reinstall a program you’ve been trialing after the free trial has ended.

Virtual Machine

My final tip for reinstalling trial software after the free trial has ended is to use a virtual machine. These are useful in many different situations, but when it comes to trialing new applications they really shine. Not only do they prevent the software from messing with your main operating system, they also prevent any security issues and can be quickly deleted and reinstalled to keep any trial running for as long as you need it to.

Free VM software such as VirtualBox is ideal for this. Create a VM, install an operating system, and set everything up. Take a copy of the image you just created, install the trial software, use it, delete the VM image, and replace it with the copy. It is more labor-intensive and more involved than some of the other methods, but it’s also the one that’s almost infallible! Using VirtualBox isn’t very difficult, but it isn’t quite a beginner-level task either; you might find this introductory guide to VirtualBox helpful.

Newbie here. If I trial a piece of software in Sandboxie. How do I then install it when the trial period has expired. Will it just not work or will it be another trial period when on my hard drive?
Will says:
I’ve been attempting to figure out what method that GR2Analyst is using to keep a log of my trial’s expiration. The first time that I utilized an uninstaller utility and then reinstalled, I did not experience this and was able to restart my trial period.
Phil B. says:
A legit reason for long-term use past the trial is older computers and older versions of RiffStation. Sonic Ladder went out of business after they lost their partnership with Fender. So since their website and FB page are no more and the last versions were given away free, then who exactly is tracking externally the trial copy installed?
Pod says:
I deleted every entry in the registry using REGEDIT, and deleted every named file with a search of C:\, and yet the software still identifies the expiration. How is that possible? Where would it be storing the information? I even turned off wifi so that it could not look at an external database
The software has databases that allow tracking if a user has already used their free trial or not. Databases save your computer’s information, which includes the operating system, device name, etc. I hope this helped.
arthur says:
Would installation in VM circumvent this?
John Vankal says:
Use Run as Date and Time Stopper software for trial reset. Also before installing use/run File monitor and registry monitor software, that will monitor every file and registry changes/created during installation, that way you can find which file and registry to delete/reset after it expired. As mentioned by the author, you can also make registry backup(export), install trial software, change date to expire, and export the registry again. And compare that 2 registry file with registry/file compare software and and you will be able to khow which key is the culprit. Nowadays, many software which involve internet connection don’t Just save the trial time counter on the user’s computer only, instead, it is also stored on their server. Usually they stored the MAC address of that machine on their server, so formatting HD/reinstalling the OS will not help. You can bypass this by changing your MAC address (there are many software to do that) which will do the trick. And the most difficult one is if they use your computers Hardware ID to saved that software info on their server( like Adobe, etc), then that is difficult now, there is a way to change HWID but, I personally don’t recommend it. But, FYI you can bypass that by changing your hard disk. :) Ok if you really into this kind of stuff, learn Assembly Language and use OllyDebugger.

Would installation in VM create a new hardware ID and circumvent it?
Zoardyeck says:
It kinda weird for me, i just formatted my computer deleting partition and create again
install the os and after all of that when i install the software i need for trial it still doesn’t give a trial of 30 days. ( it was Autocad )
Guilherme says:
Even formating the pc I can’t run vmix again. Going to try these methods.
Jeva says:
how about sentinel ldk protected with vclock. How to update the provisional v2c file.
GamingRedCZ says:
I dont think you thought it throught, because windows does a lot of changes in registry and it can break the registry, so, ppl don’t do it!
Shonzy says:
Hi just saw this great article and my contribution is absolute uninstaller. It tracks a lot of the traces of a software and uproots them. I am however struggling with one trial software called measuresquare they have upped their game quite recently. Anyone with any ideas?
Robert says:
It is mentioned in the article that you should wait for the trial to expire. I read somewhere that you should uninstall the software BEFORE the trial has expired.

Does it matter when the uninstallation is done (before/after expiration)? Or does that not really affect anything?

Thanks for a great article!

in OS use REGEDIT. Type the name(s) of said program(s) in, use “Find Next”, or F3, the continue deleting ALL instances of the aforementioned until None can be found, then, red-load & install the desired program again. Done.
Glen McPherson says:
My problem is that I have the software already downloaded on my computer and cannot delete all the files with Add or Remove programs. Your suggestions are for before I download the trial version.
What can I use to get this last piece deleted.
In Add or Remove it says it cannot find the file even though it shows it in the list.
If I download the trial version again it says that the number of loads has been reached and will not let the program run.
Abby says:
I have same problem i already installed . The software already expired . How can i continuse to use. The software cost £1000 i can’t affort to buy
Jack C. says:
Did you try RevoUninstaller or similar, per the article? Those delete Registry entries and other traces, in most cases. Unclear if that always works or something else is hidden on purpose.
