I have v5.5.1.5 x64. I found a reg key for windows ([HKEY_LOCAL_MACHINESOFTWAREPerspective SoftwareBl* IrisRegistration], and "Data40"=-) and found a way to reset the trial period. I can't however seem to find how to disable the watermark on the video feeds ("Bl* Iris Eval Version" text). I think the .dll is encrypted. Was checking with Resource Hacker, but not having much luck with finding the right DLL. Then found your gen and tried it, but it didn't work or I didn't place it in the correct file, but it made a "winmm.dll" file, which seems odd to me, but when placed in the Bl* Iris program folder it does seem to disable the trail days to 0.

 

Anyway, any advice with my attempt? Or any desire to update you gen to a more current version? I can supply their past version download link if needed. I can also make a donation if that helps. Love your past work and efforts! Thanks!
