I downloaded flash player and can't find it anywhere on my computer. When you download it does it show in All Programs or where else could I look for it? I have 2 operating systems on here and I have downloaded other programs and couldn't locate them either.

Depends where you downloaded it to.

Open the program you used to download it (ie or whatever) and see if in the options you have a default download location set.

Have a look in my documents.
