Inventor 2011 Error Message, following start up after Installation

[dsrussell]

I have 2010 Inventor previously installed on my machine.  I just completed the install on 2011 Inventor, rebooted, and on trying to start Inventor 2011 I get the following error message

"Inventor.exe is not currently registered and did not correctly re-register on start up.  This is probably because you do not have enough access rights (e.g. you are a Resitricted User).  Ask an Administrate or Standard User to re0ru n the program for you."

This error message comes up when I start Inventor 2011 and 2010.  I have registered 2011 through Autodesk, but cannot get past this error message.

Any suggestions would be very much appreciated.

Thank you

Please check if you have administrative rights on the machine.

If not, login as the administrator of the machine and try installing again.

If this does not help, create a new Windows User Account (with administrative privilages) and try installing.
