The "key file not found" error appears in case if there is no psim.sec license file in the root of the Axxon PSIM installation directory (by default, C:\Program Files (x86)\Axxon PSIM\). Also, this error is going to appear if the license file has been renamed.

Moreover, the "key file not found" error is going to be displayed when running if Axxon PSIM  cannot be run in the Demo mode (i.e. if more than two months have passed since the moment of creating the psim.exe executable file or the computer’s time is more than 00:00 and less than 08:00).

In the event of such error, put the psim.sec file in the Axxon PSIM installation directory. If the activation key file has been renamed, rename it as psim.sec. If you don’t have this file, you should apply to the AxxonSoft manager in order to acquire it.
