When you upgrade from XP to Vista and try to restore previously backed up BCM database, you might see permission related error. This is caused by mismatch between the user information stored in backup file and actual user account after upgrade to Vista. In BCM, a back-up database can be restored by the user who created database (called Database Owner) or computer administrator. After machine has been upgraded to Vista, SQL might complain that the user information stored in backup file is not valid. You can resolve this issue by explicitly running Outlook.exe process as administrator. Browse to Outlook.exe file in the folder where you installed Office, right click Outlook.exe and select "Run as Admin".
You need to run Outlook as admin only once. After successful migration, you can start Outlook normally and use BCM.
