Although the installation went smoothly (with runas Administrator), there are a number of permissions issues that I have encountered.  The one that's really getting to me at the moment is a result of the Visual Studio.NET 2005 DB2 add-in.  The error message is:

Invalid search path 'C:\PROGRA~1\IBM\SQLLIB\LIB' specified in
'LIB environment variable' -- 'Access is denied. '

Vista's new security prevents access to the Program Files directory or any of it's subdirectories from what I can tell.  Does anyone know how to fix this?
