One thought I had was if a plug-in or driver that would install under Windows 7 but might not install under Windows 8. Seems like I had read that some plugins would not install under Windows 8, but if they were installed under Windows 7 that they migrated up ok. ???
bobr,
You can install them afterwards...when you run the installer you might get a message that states:
Windows blocked this program from installing
Under that message there will be a link that says "More Info"
Click that and a button will appear that says "Install Anyways"
They will install and work...
All my plugs installed (32 and 64 bit) without issues and are working.
Cheers!
