I am unable to harvest a model into Web Portal - could not connect to ERwin API Could not detect erwin installation. I have already applied an API license to my machine to try to resolve this problem.

Problem:  I am unable to harvest a model into Web Portal using the Metadata Management UI. I have already applied an API license to my machine to try to resolve this problem. I also have r9.8 erwin DM installed on the same machine as the Web Portal.  I get the errors,

The process C:\Windows\System32\cscript.exe failed with return code 1

Process stdout log: could not connect to ERwin api:  Automation server can't create object

MITI.MIRException: [MBI_ER9_E0059] Could not detect erwin installation.

[JBDG_F0006] The Java process did not complete successfully. 

Solution:  the Windows user lacked privileges to access the API that is a part of the erwin DM installation.  

Applying full privileges to the erwin DM install folder did not resolve the problem:

When a more privileged Windows user logged in and then registered the API license, then the problem disappeared and the models were able to be harvested using the Metadata Management UI.
