SharePoint Upgrade Issue

I have faced a weired issue while upgrading SharePoint Server 2007 to SP1 on one of our development servers. Whenever I executed WSS and MOSS upgrade installer, it gives me error “detection failed, this could be due to corrupted installation”. I tried following to overcome the issue but none of them actually worked:

  • WSS SP1 wizard failed
  • KB941422 execution failed
  • Force upgrade with psconfig command line “psconfig -cmd upgrade -force” failed
  • “stsadm -o upgrade -forceupgrade -inplace” also failed
  • Disintegrated server from farm but it still failed

Then I came across a blog entry at the following link:Blog Entry Link

As per this entry, I tried to find the registry entry, but it was not available. Then I figured out that some admin had tried to manually remove SharePoint, while doing so some registry entries were removed. So whenever, installation started it checks the registry database and as it found no entries there, it just fails.

In order to resolve this issue, I used Microsoft Registry Cleaner that could be found here: MS Registry Cleaner. After that when I executed the installers everything worked like a dream 🙂
