If you’ve recently installed a new instance of Workflow and you're experiencing difficulty launching the applications, it’s likely the result of an issue on certain Windows Server 2012 and later environments.
This is caused by a missing file on the Windows server environment and can be resolved by downloading the attached file and following the steps below:
-
If the Workflow service is running, navigate to Control Panel > Administrative Tools > Services.
-
Right-click Perspective Workflow, then click Stop.
-
Download the MSCOMCTL.OCX file at the bottom of this article, then save it to a directory on the server.
-
Move the file to the appropriate folder:
-
If your Windows operating system is 32-bit, move the file to C:\WINDOWS\system32
-
If your Windows operating system is 64-bit, move the file to C:\WINDOWS\syswow64
-
-
Open the Windows menu, then search for Run.
-
Copy and paste the following command in the Open field:
-
If your Windows operating system is 32-bit, paste regsvr32 C:\WINDOWS\system32\MSCOMCTL.OCX in the Open field.
-
If your Windows operating system is 64-bit, paste regsvr32 C:\WINDOWS\syswow64\MSCOMCTL.OCX in the Open field.
Note: If you receive an error that states "C:\WINDOWS\system32\ MSCOMCTL.OCX was loaded, but the DLLLRegisterServer entry point was not found. The file cannot be registered” clicking OK will still successfully register the file.

Click OK.

Navigate to Control Panel > Administrative Tools > Services.
