Rational product launch results in "FLEXlm Error -88, System clock has been set back" error
Attempts to launch an IBM Rational product results in the error "Failed to check out a key".
The full error message is as follows:
Failed to check out a key for RationalSuiteEnterprise:
FLEXlm Error -88, System clock has been set back
Changing the time back does not fix the error.
The system time of the license server has been set back, either via the Date / Time Property on Windows, or in the BIOS.
Resolving the problem
Reset the time on the license server to the correct date and time normally fixes the problem.
However, if you went into BIOS to change the time, and set the time back to what it should be, but the error still does not seem to go away, stop and restart your Rational License Server.
Another possible cause is that certain files were created during while the system time was being set forward. So search your drive for any file that was created after today's date, and remove them.
