As stated in one of the Adobe troubleshooting sections I read, the CS4 components require a separate CS4 serial number. Greetings! I installed CS on my bit system, which means I had to install the included “complimentary” CS4 copies of After Effects & Premiere Pro.
Always use the suite installer, not an installer for a single product, unless you have Acrobat 9, Adobe Premiere Pro CS4 (32 bit), or After Effects CS4 (32 bit).
