Doing a clean uninstall / install is especially recommended if running into issues during an upgrade of OWB. Sometimes, due to permission restrictions or other issues on the machine, some of the OWB components do not get uninstalled on their own. If that is the case, a manual uninstall is needed to remove the remaining components.
2. Clean out the Registry
4. Go to Add/Remove Programs again and check that there is no trace left of the products that you have removed at step 1.
5. Delete the following folders if they are listed (First make a backup of any views you may have saved in the folders if they are still there):
Please note that on workstations running a 32-bit version of Windows, the folder names will be prefixed with C:\Program Files (x86)\ instead of C:\Program Files\.
6. Reinstall OWB.
