ok so I downloaded the 64bit version of the RC and installed right away on the test machine, then after setup was complete I changed the desktop to my favorite image (a bullfighter).
Next I downloaded AVG (latest) from download.com, funny thing is that after it was downloaded (when I went to double-click to open), it didnt have an extension, the mouseover gave me a 7zip file, but it didnt have a 7z extension, and when I doubleclicked it asked for what program to open with, huh?
so I tried to change the extension to a zip, duh wrong, then after applying, changed it to .exe, which then gave it a .exe.zip, not good, so I went to change thru properties and removed the zip, and added exe with IE8 as the program to open with, I didnt do it, I tried to give it a different "other" (none) program but it gave it IE8.
So then I went to file and double-clicked to open, and Windows 7 went berzerk, trying to open, then closing IE8 windows so fast you gotta see the video I took. Here's the link:
What finally stopped this was to revert to old name, zip.
