I'm sure will you get a solution for your problem, but you could also try opening the source code solution e re-building it. This will register the DLLs and get you going.
Hope it helps.
If StrataFrame does not appear in the Add/Remove programs then you have other issues. I have not heard of this (outside of improperly deleted registry keys). Your registry still thinks that there is an MSI of StrataFrame installed.
At present, you have to manually uninstall previous versions when upgrading. This will be resolved after the first of the year when we introduce a new installation that will automatically remove previous versions.
