For those of you who have installed the CS4 Master Collection and months later received a “License for this product has expired” popup when trying to open Photoshop or other CS4 applications. This workaround will fix your licensing woes indefinitely
The main problem is that after a certain period of time, the AMT Licensing file refuses to allow the CS4 application to load
Apparently after reading around, it is discovered that the amtlib.dll file that is contained in each individual application folder in the CS4 Master Collection needs to be replaced with a “lifetime version” to get your product working again. Contained in this download is the amtlib.dll file as well as a crack.bat script that will replace each old amtlib.dll file in each program folder with the “lifetime version”
There should be no need to change your serial, but a keygen that works is included if anyone needs it
