Had a major crash so bit the bullet and went for a fresh re-install of Win & Home 64 bit. Now it will only let me reinstall a few progs previously downloaded. It comes up with a message that says:
The version of this file is not compatible with the version of Windows you are running. Check to see wethere you need a 32 or 64 bit prog and contact the software publisher.
These progs all downloaded and installed before. Any ideas? I have switched off UAC to no avail. It also seems to install freshly downloaded files.
