Encrypted serial key not found

In our enterprise wide deployment we see that in very minimal systems the "ENCRYPTED SERIAL KEY" was not found in registry or in the regid* folder under "programdata". This is not only Acrobat specific but also for CS package.

We found this while doing an internal software compliance audit and the auditor mentioned that even though we have enough licenses we should be able to get the encrypted key to check against the actual deployed key.

We tried to uninstall, reboot the machine and reinstall the software without any success.

Please help me in resolving the issue and Is there any known issue reported on this?

We raised a case using chat but they informed that i will get a call back which did not happen yet. The call log id is 0187833061.
