Erm, that is a classic solution for the "invalid 32 bit app" error. And it is very logical they gave that response (which would not have worked for you).
I see no mention of the "app has failed because its side-by-side config is incorrect" error. And that was the most important thing to mention and report!!
And because you had this error the origin of the "invalid 32 bit app" error would most likely be completely different and only secondary as a result of the first error.
I'm sorry to say this, but this is a perfect example of how people do not report errors properly and yet expect MS to respond with a proper working solution....
Moral of the story: you should have reported everything, from the beginning, in detail, especially the "side-by-side" error.
