Windows 7 Home. tmg8setup.exe downloads ok. Open the exe and get the "do you want to run" message. Reply yes. Get the "select language" message. Reply ok. The progress bar runs up to the 30-40% value within seconds then an "Advanced Installer" window message appears: "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package". Reply ok and install ends. There is no TMG V8 folder built on C drive. 1. Turned off Norton and same failure. I have V7.40 installed but not the V8 Beta. 2. Have unblocked the security setting in file properties. 3. Run as Administrator. None of the above corrected things. Any ideas.
