Hi! I try to install QV9 on Vista Ultimate 64 Bit. The installation ended with "Installation ended prematurely because of an error". I tried both QvSetupRedist_Eng.exe and QvX64SetupRedist_Eng.exe with the same problem. I also tried to manually register vbscript.dll and I tried to step or iisreset the IIS. But none of these action seem to have any impact on the problem. Has anyone any additional ideas? Is there an option to trace the installation to get a better error message? Thanks in advance for your help. kind regards, Patrick Theobald
