Hmmmmm,

What answers did you give to the two messages?

The second one is more interesting, as Windows should give you a similar warning that you are trying to update a newer file with an older one, and I am guessing that you don't get a message like that on the boxes where the installation works?

You might check with your colleague to see if he gets a windows message like that?

Please check the properties of the resident OLEAUT32.DLL files on your macine, your colleagues, and one of the machines where the upgrade works............date/size/version/last modified etc.

I am afraid it might be similar to a problem I had with MDAC versions. It looks as if you have installed something that has done a secret update of Windows components, and this is incompatible with your new installation.

Just a thought
