When you try to uninstall SAS OLE DB Solution from Control Panel>
Add/Remove program, SAS OLE DB Solution is not removed from the
Add/Remove list.

You might see the following error message:

   Uninstall
   Unable to locate the installation log file 'C:\Program Files\SAS
   Institute\Shared Files\SAS OLE DB Data Providers\Uninst.isu'
   Uninstallation will not continue.

Note:  The path might also be:
   C:\Program Files\SAS\Shared Files\SAS OLE DB Data Providers\

The SAS OLE DB Solution is a shared bundle that can be installed either
interactively or by other SAS setups. If the bundle is installed
interactively, the Add/Remove programs entry is added. If the bundle
has more than one product that uses OLE DB, the uninstallation of each
product removes its entry until all of the consumers are gone.
The bundle is not removed until the last consumer is removed.

You can see the consumers by viewing the subkeys of the following
registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\SAS Institute Inc.\Common Data\Shared
   Files\SAS OLE DB Solution\Consumers

The SAS OLE DB Solution and the Add/Remove Programs menu option both
disappear as soon as you remove all of the consumers, the same behavior
as that of any of the shared bundles that might be installed both
interactively or as a bundle.

If you then tried to install OLE DB, there are no complications and you
can install successfully.

Warning: Always back up your registry before you make any registry
   changes. For assistance, see Windows Help, Microsoft documentation,
   or the Microsoft Windows Web site. SAS is not responsible when
   you edit the Windows registry: changes in the Windows registry
   can render your system unusable and will require that you reinstall
   the operating system.
