I have the exact same problem and I did also a clean installation and followed the instructions to enable UAC. However the problem still persists. It suddenly started yesterday before that everything was fine and I already had v1.5 Beta R7 installed.
I restarted the computer and then I was able to install v1.5 Beta R7 again successfully. However, when I tried to spectate a game i got the message in the screenshot
It says that v1.5 Beta R7 is either not intended to be used with windows or that it entails an error.
I'm trying to install the Patch v1.5 Beta R7 but it keeps saying "Error installing package (Error: Unzip failed)".
I already made a clean install and the diagnostic tool says "everything looks fine".
Can anyone help me with this and tell me how to slove that problem?
Thanks in advance
David
