I had not problems with the upgrade from 5.2.37 to 5.2.38 on Windows 7 Ultimate 64-bits. Which Windows version are you using?. Have you tried to remove and reinstall it?. Thanks in advance.

The problem occurred when I upgrade without remove old Workbench. When I uninstall Workbench, all work well. I'm using Windows Professional SP 1 x86.
I think that the setup kit should include the remove old version before install. This will help user so much.
Thanks for support me.
