When I use this connector in Windows Vista RC1 with .NET2 and I try to fill a DataSet with a DataAdapter I get this exception:

System.UnauthorizedAccessException was unhandled
  Message="Access to the registry key 'Global' is denied."

If I run the program in 'Administrator Mode' the exception is not throwed and everithing works fine. In Windows XP SP2 this the exception is not throwed.

How to repeat:
Create a Connection, a DataAdapter and fill a dataset in 'Normal User' mode.

Thank you for a problem report. Please, try to repeat with a latest version of Connector/Net, 1.0.8 RC, and inform about the results.

The 1.0.8 RC works perfectly as the 1.0.7 does. The problem persists with the 5.0.1.
