Error removing Update Manager

Hi all

Thanks in advance

I´m trying to remove update manager v4.1 and I have this error:

Error 25061. Setup failed to remove the DSN used to access the local VMware vCenter Update Manafer database

Then click OK

and it rolling back

I review DSN and every think is OK

Have you got any suggestions?

VCenter 4.1

VUM 4.1

VCenter and VUM in the same Virtual Machine.

Regards.
