Issue:
I just installed R13 workbench on Windows Server 2016 64-bit. I am getting following error message:

An error has occurred. See the log file
null.

If we right-click and select "Run as administrator" when starting Workbench, we find that this works correctly.
Environment:
CA Harvest SCM Workbench client v13.0.3
Windows 2016 platform
Cause:
This relates back to a special permission needed by the Eclipse platform that Workbench is built on. 
Resolution:
In Windows Explorer, navigate to the %CA_SCM_HOME% folder 

Right click on the Configuration folder and select "Properties" 

Click on the Security tab 

Click "Edit" 

Select the "Users" user group above and check the "Full Control" checkbox below. 

Click OK to confirm. 

After this Workbench can start normally.
