Yes its version 4.7.7.5
The error persists
I was able to finally uninstall by using this program and then reinstall the latest version.
Seems like my story is not finished. I was now stuck on version 7.7.9 and I cannot update to latest. I have also uninstalled and reinstalled but it still was the same old 7.7.9. In the end I uninstalled and discovered that all the files was still present in c:\Program Files (x86)\Britton IT Ltd\CrewChiefV4\ so I renamed it to CrewChiefV4_old and then reinstalled. finally it was updated. This MSI stuff is really weird. I don't have any other apps with problems.
