Error while starting Autodesk Vault 2011 Explorer

[Anonymous]

Hi,

on one of our machines (Autodesk Inventor 2011 SP 2 / Win 7 SP 1 x64) we are getting a really strange error message while starting the Vault 2011 Explorer (see attached file). I can't find any information in the event log of windows about this error. Furthermore this error message does _not_ appear when the user logs into the vault within Autodesk Inventor 2011. So it does only appear when starting the Vault Explorer directly.

Has somebody any advice how to get rid of this error message?

EDIT: I already tried a repair installation of Inventor 2011 and of Vault 2011 but without any success.

If you have a different Windows user login to the machine and run Vault Explorer, do they get the same error?

Unfortunately this also happens when I am logged in with a different user which also has administrative privileges.
