Well I've reinstalled to a different drive and I've managed to get it to show as 1.6 installed, however I still have a problem installing 1.7.
When I run the 1.7 Patch installer, it says 1.7 is already installed and do I want to un-install it, I say yes, then it says it cannot find the .msi file to un-install.
All very strange.!
If anyone can find any destructions (instructions?) to manually change the registry so that I can install patch 1.7 it would be most appreciated.
I've tried CCleaner, and RegCleaner to no avail.
