Allester 0 Posted March 17, 2010 OS: Windows XP Home edition Ok, going over this site everyone seems to have a completely different problem then me. I don't need help RUNNING THE GAME. My problem is this: When I try to INSTALL M&M7 & 8 I get an Installshield error. I have updated my Installshield to Version 11, Updated WindowsInstaller to Version 4.5 and I cleared out the Temp files, ensured the WindowsInstaller was Started, and everything I can think of. I still get the same Installshield failing error. I HAVE had these games Installed to my PC perfectly fine just last night, but I had to format my drive for several reasons and reinstall, then this occurred. This is the Error I receive every time: AppName: _ins5576._mp AppVer: 5.53.168.0 ModName: zdatai51.dll ModVer: 5.50.131.0 Offset: 00004827 Any assistance would be greatly appreciated.
