I did install from within Vista. I thought I was getting an "upgrade", but Win7 told me I couldn't do that, so had to do a "custom" complete installation. I didn't change any of the defaults, and this is what I got -- both Vista and Win7. It's a pain -- I moved Firefox over to C:, but now I can't download Adobe or get any .pdf files to open. At least I can print to my network printer from Win7, which Vista won't allow.
If this is the type of thing that's going to continue, I'll go back to Vista, as much as I dislike it.
