Summary

During installation of the Arcana Scheduler, or when starting the Arcana Scheduler service after installation, the program fails with an error similar to the following:

ADScheduler.exe - entry point not found. The procedure entry point @ADLicenseCertificate@FirstCertificateforProduct$qulpc4boolpp20ADLicenseCertificate could not be located in the dynamic link library adlicense.dll.

More Information

This problem occurs when you are downgrading the Scheduler (installing a version of the Scheduler after removing a later version). It occurs when one or more DLLs are not removed properly during uninstallation.

Workaround

Check the Arcana Scheduler program directory and the windows system32 directory for the following DLLs, and delete them if they are present:

   adscheduler.dll
   adlicense.dll
   adutil.dll
   admail.dll

Then rerun the installation.
