I am having a hard time getting my WinZip installation to recognize the WinZip.wzmul Multi-User Registration File. I am on a Windows XP and have put the WinZip.wzmul inside of C:\Program Files\WinZip. However, when I start WinZip by going to Start -> WinZip 15.0, it says this copy of WinZip is not yet registered, and that I need an registration/activation code. This webpage says that the presence of WinZip.wzmul in this folder will convert WinZip to a licensed, registered version but this is not the case in this situation. Any recommendations? Thanks.

I dont know if this still holds true, but in the past all you had to do was double click the .wzmul file to register. I would keep the .wzmul file with the WinZip MSI file on a network share, and after installing WinZip from the MSI, I would double click the .wzmul file and that would complete the registration.

Hmm I tried double-clicking the .wzmul file, but it just takes me back to the registration page. I wonder if my .wzmul file is corrupted or something. – O_O Aug 25 '11 at 0:47
You may be right, check with WinZip support. – Keltari Aug 25 '11 at 0:47
