There’s nothing worse then getting your hands on some sweet Adobe product and no be able to install it. It takes the situation from a joyous one to that of despair. If you’re unable to install due to an Invalid Serial number issue then read on. The information is valid for creative suite 1, 2 and 3 products.
One of the main causes of invalid serial numbers is mistyping them, so you may want to check on that first. Solution 1 should take care of 95% of serial number issues, when the serial number itself isn’t the issue.
Fixes for InDesign Invalid Serial Error:
1. Restart your system in selective startup mode, install
2. Delete Temporary Files, install
3. Create a new administrative user, install
4. Make sure there’s only one installation in progress, install
5. Installing from individual CS2 disk. If your version of InDesign is part of the suite then you need to insert disk 1 first to install. Otherwise it will never accept your serial number.
