I had a very similar situation, though I'm trying to re-install on the same laptop after having to reformat my hard drive. (I purchased CS5 Production Premium, I have a serial # key, and it appears under "My Products" but not "My Order History"). I tried the direct download links that Mylenium shared (thanks!), but any time I tried to find a download for a CS5 product, I was re-directed to try CS6. I noticed that the tail-end of links had a "?PID=" followed by a 7-digit number. I don't know if that's a Product ID or a Purchase/Purchaser ID, but something appears to be diverting my ability to access and re-download the CS5 suite I'd previously purchased. Any suggestions/recommendations?
The exe file which you are downloading will decompress the .7zip file. You can find more details on how to extract the installation files at Start the installer after downloading - -suite/kb/start-installer-downloading.html. 2b1af7f3a8
