After upgrading Windows forwarders from Splunk 6.1.1 to 6.3, why are we getting error "app=Splunk_TA-windows: action=Uninstall result=Fail"?

We recently started trying to upgrade our Windows forwarder installations from 6.1.1 to 6.3, after the upgrade, the Forwarder management page states the forwarder has errors installing. The `\Splunk\etc\deployment-apps\Splunk_TA_windows` folder is there and looks fine. This only affects the forwarders that we uninstall the old client and install the new client. This is already installed on the forwarders before the upgrade, the forwarder for Windows is not changing... I am unsure as to why I am getting this error Has anyone seen anything like this? 10-15-2015 12:56:35.424 -0400 WARN ClientSessionsManager - ip=10.0.0.8 name=11111111-1111-1111-1111-FBBDE9BD3C6E Updating record for sc=Windows Clients app=Splunk_TA_windows: action=Uninstall result=Fail
