If you click a link that does not have those steps listed, open a second window using the Lightroom 3 link to see those 'Important Instructions'. check your account for its serial number if you can't find documents with it, Adobe ID. They are critical especially steps 1, 2 and 3. acrobat pro 9 is supposed to be part of that suite but if the installation files are on a separate disk like you describe it has a different serial number from the cs5 suite.

ie, you can have a valid serial number, but if it's for program A and your installation file is for program B, you will see an invalid serial number message.Ĭommon mismatches are language/region (eg, serial number is for western europe and installation file is eastern europe), platform (eg, serial number is for a mac and installation file is win), license type (eg, education vs enterprise vs individual).Īnd one of the most common is using a program installation file with a suite's serial number.

Assuming you're using a valid adobe serial number (6 groups of 4 numbers), you have a mismatch between your installation file and serial number.
