Installer says Creative Suite 5.5 Design Standard serial not valid
I decided to install Windows version of Creative Suite 5.5 Design Standard (English version) which wasn't used it in years. I went ahead and registered both Windows and Mac versions successfully on my Adobe account. After setting up a Windows 7 Virtual Machine in VMWare, I launched the installer but when I wanted to use the serial number which I used to register the product, it gave me "serial not valid" error. It installs fine in trial mode which imho rules out any software incompatibility issues. What could be the problem and how do I go about fixing it?
It seems like a common problem based on what I've been reading on these forums. Can anyone check my serials and explain what seems to be the problem as I'm certain my serials are valid.
