After many days of hair pulling and abuse, I have found a way to re-install/repair the latest version of DM (7) on WIn7
It appears the issues are actually related to Windows Installer and not RIM.
Simply rename the selft extracting 700_b060_multilanguage.exe to .zip.
Extract the zip file contents into a folder and install from the folder.
