For those of you who want to crack cleanly installed 9.5 with l-mqt82.exe:
You need to create :\Program Files\Common Files\Mercury Interactive\License Manager
folder on your system drive. Then run the l-mqt82.exe and open generated "lservrc" file in text editor. Copy everything before "QuickTestPro" version "6.0" and manually enter it when QTP asks for the new license key.
