People who use adobe products and who update to the newer versions are sometimes stuck in “License Expired” error messages after installing there favorite adobe product.
Now some background information: Adobe’s license manager which is installed by latest adobe products stores the licensing information in a file called cache.db. located usually in “C:\Program Files\Common Files\Adobe\Adobe PCD\cache” or “C:\Program Files (x86)\Common Files\Adobe\Adobe PCD\cache”. (if your windows installation drive is C:). Copy this file to somewhere else for editing purpose.
This file is actually a sqlite database containing rows and columns. Therefore, we can manually edit or delete the rows in the database by using a sqlite database manager application such as SQLiteman. which is a freeware application and works very well in this situation.
We open the sqliteman program after installation, and then open the cache.db file in it. After opening the file, “Tables” and then select the “domain_data”. You will see the rows and columns and all the fields that the table contains, in the middle of the program window. Now have a look at the following image carefully.
As you can see, there are some rows with value = rejected. we just need to delete these row one by one selecting each of them and then press the Red and white colored delete row button (second one).
After making the changes to this file, we can save it and then copy it to the original location overwriting the original file. Now restart the computer and open that adobe product again which showed the “License “
