2. Click Start, right-click Computer, and then click Properties.
3. System Properties will open. Click the Advanced tab, and then click Environment Variables.
4. Click the New button.
5. Enter MIG_UPGRADE_IGNORE_PLUGINS into the Variable name field.

7. Click OK three times to close the dialog boxes.
8. Re-launch your Windows 7 Upgrade installer!
