I have the same issue only trying to download and install the latest 9.0.2 version. I've checked the MD5 and it matches but when I try to right-click the installer and extract the content it fails using WinRAR. I don't know if there is something wrong with the installer or what but this is a brand new computer, WIndows 8 x64, UAC off, Local Admin Account, I've go no other version of VMWare installed so there is nothing to uninstall or remove from the registry (although I checked anyway), even though there was nothing related to VMWare other than the logs in the %temp% folder I deleted it all anyway, I'm out of ideas and patients at the moment.
One of the main reasons for upgrading to the new computer was to use VMWare for the application testing across different operating systems and if I can't figure this out soon I'm going to have to go with something else...
I hope not.
