It is annoying when a trial expires before you had time testing the software. Sometimes it is just enough to reinstall to get a new trial period but usually they hide the information so it is persistent.
I used Sysinternal’s Process Monitor to find out what resources the license manager (PsiService_2.exe) used and cleared them away to get a new fresh trial period.
If you have licensed products using this service you should be careful and keep backups of all values/files.
These instructions are valid for Windows 7 64-bit but just remove “Wow6432Node” for 32 bit systems:
- Stop “Protexis Licensing V2”-service and the application you are evaluating.
- Clear registry:
- HKEY_USERS\.DEFAULT\Software\Protexis\Licenses
- HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Protexis\Licenses
- Delete files:
- C:\ProgramData\KGyGaAvL.sys
- C:\ProgramData\88AD984CE6.sys (filename varies)
- Start service
- Start the application
