Reset the trial counter on O’Print “AirPrint Activator for Windows”.

If you ever have the need to hack or crack the trial period on OPrint – an airprint relay / proxy / print server for Windows then here is how.

Quit OPrint
Delete the following registry keys and their sub-values.
Delete the following file

Re-open OPrint. The trial will be back to 30 days.

However – this software is reliable and fully worth paying for. These instructions might be ideal if you installed it and then forgot to test it before the trial period expired.

  1. Hi – We have purchased this O’Print software but it needs a direct internet connection to register and it is on a virtual machine with a proxy server. The instructions no longer work for resetting the trial and it expires today. I’ve obviously contacted O’Print support but haven’t heard from them. Do you know of another way of getting the licence key into the program through the registry or by editing another file? Regards, Andrew

  2. I’ve just re-tested my instructions and it reset my trial period on the latest version. I suspect somehow you’ve not deleted all the required files. If you are totally sure you have – what OS are you running it on and 32bit or 64bit ?

  3. Thanks for your reply. Re-reading your instructions I was originally looking for registry values that weren’t there. I’m still awaiting a reply from oPrintware after over a week but at least this has got us up and running for now. Thanks again!

    on my system C:\Windows\SysWOW64\config\settingenv does not exist.
    But only delete the registry keys seems to be not enough to reset the trail.
    I run Win 10 x64 Pro.

    Any hints?
    Regards, Killroy

  5. Made sure you’ve unhidden system and hidden files maybe?

  6. Killroy says:

    Thats the point :)
    First make hidden files an folders visble.
    Thank you very much.

  7. yemen is the best says:

    to increase trial time to unlimit use program (runtodate) i test it and work with it very well

  8. đức đại ca says:

    Me too => on my system C:\Windows\SysWOW64\config\settingenv does not exist. I do make hidden files an folders visble done. ?? Windows 10 64. thank

  9. untick “hide protected operating system files” too?

  10. Dudester says:

    Same problem here. Unticked “hide protected operating system files” and ticked “show hidden files, folders and drives” and that settingenv file doesn’t exist, at least not in C:\Windows\SysWOW64\config\

    Win10 64 here too.

  11. Dudester says:

    The suggestion for using RunAsDate works well though.

  12. Run as Date didn’t work for me but looks like deleting the below two files did the 3rd didn’t seem to exist

  13. Peter says:

    I think there must be an equivalent solution for windows 7 32 bit. if there is, it would be very much appreciated if you could post it here. Thanx.

  14. Probably the same but without the Wow6432Node and on the file system system32 rather than syswow64.

  15. Peter says:

    Thanx, it worked great !

  16. bat file says:

    reg delete HKLM\SOFTWARE\Wow6432Node\OPrint /f
    reg delete HKCU\AppEvents\EventLabels\option /f
    del /A:H “C:\Windows\SysWOW64\config\settingenv”
    timeout /t 3
    start “” “C:\Program Files (x86)\OPrint\OPrint.exe”
