Reset Trial Software and Extend Evaluation period to run forever

Some program runs fully functional for a limited period of time say- 30 or 45 days. These are called as Sharewares ans stops executing after that period of time and asks you to purchase the program. Well, you can by pass trial period restriction extend it by running a program in the date and time that you specify without changing System’s Date and Time.

Unfortunately, you only get 30 to 90 days of time to use any product on demo trial basis then, you need to upgrade it to full version or say purchase it. But Now, you can save your money by using the same software forever without paying any cost.

Good thing about this program is that it doesn’t requires installation and you can run multiple trial software at different timings and date. It intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify.

How to run Trial software forever?


TimeStopper is a small program which stops the time for any software executable file and hence facilitates you to use extended trial version of the program. After downloading, Just browse the EXE file of that program generally located in C:\Program Files and select the new installation date. Your program is now extended to another 30 / 90 days depending on the software.

Time Stopper Working demo

Now that you are ready with time stopper, You must remember that the new date will be the date you installed the trial software. This will maximize the Trial period, so just keep the installation dates of trial software noted in a text file.

Download: Time Stopper

Run As Date

Download and install Run as date. Target the location of the EXE application of the trial software you want to run which is generally in ( C:\Program Files \ Program Folder ) Specify the desired time and date at which you want the software to run. This should be in the past like Yesterday or 5-6 days before. Please note that- You should not take this date before the installation date as some programmers are clever enough to block software and end your trial period.

Here is another program on which I tried extending its trial period of 30 days. I cannot guarantee that this software will be able to crack and extend trial period of any software but most of them can be done. This may not be able to crack Antivirus or Internet Security programs which generally stores this data on Web servers which cannot be hacked. This tutorial should be taken for education and testing purpose only and not for any illegal usage.

Note : This program just extends the trial limit of any software by changing the installation date. It doesn’t mean that you get the Full version of that produce. It means that the demo software (with limitation if present) will be available forever.

Nice share Rohit, im going to try this with Roboform free. It stores unlimited passcards if you have the pro version, but only 10 if we have the free version

    Rohit Langde - April 19, 2010

    Thank you Ashwin but I don’t think it will work because, we can only specify the date of running a program and not extending it’s functionality.

      Ashwin - April 19, 2010

      Wll, im still ising the trial version of Roboform pro. It will turn into Roboform free after the trial period. Not sure how i can reset it though

        Rohit Langde - April 19, 2010

        See, Functions will be same as of now but only thing is that- you will be able to run it even after trial expiration.
        Try .. It may work for you.

      Ashwin - April 19, 2010

      Sorry about the double post, just wanted to inform you that I have switched to Keepass, an open source password manager, same features of Roboform pro but its free. (addon for firefox)

        Rohit Langde - April 20, 2010

        That’s good. Rather than using illegal keys or something it’s better to use opensource freeware. No time limits or Function limits. Cheers!

VIKASH - April 20, 2010

I will give a try
thanks for sharing

Dear Rohit Langde:

English is not my primary language. Sorry I do not undersand this portion. Do I change the date, prior to hitting finish/run software, or do I run the software with the original evaluation, and then change the evaluation backward from the date of installation.

Most of my software is donated as I have no personal credit card and I perform my work since 1967 for no personal financial compensation. Do have personal money to purchase sofware. (If really need a certain software the company will not donate, the I would like to extend the valuation if and when possible.

Thanks in advance for your anwer.

Best regards.

    You can try it either ways, no problem.

    Install a trial program. Do not start 1st time. Then simply freeze C: drive with Deep Freeze program. It will start forever in trial mode. To avoid freezing main C: drive simply download free VMWare Player, and make a virtual computer and install all your trial programs in your virtual computer which is always frozen. This method works 100%. No more cracks or fake numbers plus you can make copies of your virtual computer with copy/paste and it will work on a MAC or PC and can be carried on a USB stick. The latest PS CS6 MSTR Collection is really nice, ha ha, enjoy.

      Nice hack…who would have thought. At least I don’t have to worry about some dumb@#@ putting a horse in a keygen anymore. Good look..

      HI, Bob..I don’t really understand your is VMWare Player like pararell? Im using mac and want some use trial programme forever..please reply me @

I could not get Time Stopper to work with Corel X5 or AutoCAD 2012. But I think it maybe due to not setting the dates correctly.

What do you think of this idea? Reinstall Windows and immediately install all the important software. Do a SYSTEM IMAGE backup. Then every few days, or before the trial period expires, just recover the original registry settings.

Yasir Imran - October 23, 2011

It didn’t work for Corel Draw X5

P - January 13, 2012

When you’re trial period is ended, you van change THE date for working That day. Aldo you van change THE date for instal à crack version.

Dear Rohit,

If I am using a trail version of a time based software (which automatically saves files every hour) will it work because Time Stopper did not? Thanks

    Rohit Langde - November 5, 2012

    The software works for the Software which are Time based trial only. If the software has limitation or not fully functional in its trial version then, Time stopper won’t be of any use.

kochi - November 14, 2012

Will this program work for Autocad 2012 trial? its a 30 day trial with fully functionality. I am seeing above that it’s not working for someone.

these heavy duty programs like adobe, autodesk, corel and etc have teams of ppl thinking about these issues and I think they probably have security measures in place..

anyone had luck with autocad and this time stopper program?

Shekharmine - December 12, 2012

How it works??
what is the code for change the code in registry??
HKLM/Software/Microsoft/windows/current Version/Install Date


Shridhar - December 23, 2012

It’s not working with Quick Heal. Any suggestions?

Aakash Sharma - March 14, 2013

I wanted to learn how to track each and every location where a new software install would make changes. Also, I wanted to know the registry files it would create.
For this I downloaded 2 open source software: ‘Sys Monitor’ and ‘CRegistry Comparison’.
Also, for the testing purpose only, I downloaded and installed a new copy of ‘Image Cut'(A photo splitting tool), which was a 17 days trial.
After waiting for two days when the software reported 15 out of 17 days remaining, I tracked the the activities going on in my PC (running Windows 7 ultimate – 32Bit) on the new install and uninstall of Image Cut for the registry files and files copied to disk.
Then, I deleted all the files and registry keys where ‘Image Cut’ had made changes. Also, I cleared all unnecessary files and registry keys with ‘ccleaner’.
On installing the package again (when I had already clered all those files I could track which pertained to the ‘Image Cut’ software.), Image-Cut still showed “15 out of 17 days left” which then further turned down to 14 the next day, i.e., the timer was still goin on at some place. Though I had deleted files from regedit.exe, app data, temp files and prefetch, still I couldn’t edit a few files such as “c:\windows\system32\SYSTEM” tracked by ‘Sys Monitor’. (I tried to open this by running notepad in adimnistrator mode and browsing for ‘SYSTEM’ file with no extension. It delivered an error message saying file was already running. Obviously it would run as it is a system file). So I have a doubt on this file too as all others could be erased but not this one: neither edited nor deleted (though I wouldn’t delete a system file under normal conditions). I had restarted my computer whenever I felt suitable to do so between the steps I followed.
I have no use of ‘Image Cut’ for myself and I have set it as target for informational purpose only because I want to know how the things work out in my own Computer.
Please can any technology expert help me in erasing all the traces of the software so that on a new installation, the timer is reset. If further information is required, you can ask me for logs at “”. If you get a clue kindly elaborate all the steps involved. Thanks in advance.

Since I want to learn the true mechanism, plaese avoid guiding me to use: “Total Uninstaller”, Run-as-date, Sandboxie, Virtual Machine etc.

    Rohit Langde - March 14, 2013

    Hi Akash, I appreciate your level of understanding and the experiments you did.
    Honestly, I even don’t the exact mechanism involved behind this. Always thought that, Registry Key is what all a software injects to track installation date.
    But, one thing I know is that the mechanism varies from software to software. 2 Years ago or so, I completely flushed off Quick Heal Traces and was able to reinstall it again with countdown reset. However, this didn’t stand true for another application called Horoscope Explorer.

    Just like the ways of Activation and the way their algorithms are defined to create Keys, this Trial thing also varies. Some maybe just inserting a registry key while some wise developers maybe using complex technique like the one you mentioned.

    Hope you somehow figure out the working used by most of the software developers soon. And I would appreciate if you share it with us 🙂

      Aakash Sharma - March 15, 2013

      Thanks for the reply sir. If I get any way to crack this stuff, I would definitely let you know.
