Product Key saying invalid for CS4

I purchased Adobe CS4 many years ago and am trying to install it on my new computer. Now when I get to the product key part of installation it is telling me I have an "invalid product key". I am 100% sure this is the correct product key as it was previously installed on my old computer. Can someone explain why this is happening now?

Did you check your Adobe account to ensure you have the correct serial number for that product?

Was CS4 an upgrade?  I ask because if it was, you'll probably need the qualifying product's serial number.

    I believe it is the correct serial number since I am installing off of a disc, not an upgrade. I purchased it as an extenson of the 30-day trial about 10 years ago.

    1 - did you DE-activate before so your two allowed activations are available?

    2 - where did you buy, and are you sure it was from an authorized dealer?

    3 - read below

      Hmm I will see if I can get the old laptop up and running and deactivate it. I didn't know it was limited to 2 activations so maybe that is it. Can't ever recall installing it on a second computer though, but seems the most likely scenario. I bought directly from Adobe and have the hard discs so I know it is reputable, just a very long time ago haha.
