This link discusses the error message you gethttp://www.windowsbbs.com/showthread.php?mode=hybrid&t=10150
and it seems unrelated to the Photosuite4 installation problem.
Google search indicates that application maybe from one source (MGI) or another (Roxio).
Dependent on it's exact issue date, I guess.http://www.google.com/search?hl=en&q=Photo...G=Google+Search
It also appears that the version4 is an older version, perhaps OK in your case,
but then again, perhaps another program might be appropriate, too.
Do you have any other image editing programs?
I think it should be clarified what your intended use of the Photosuite4 is ...
Why it is not installing could be conflicts with other applications,
conflicts with the winXPhome service pack or recent updates/patches,
I'm just not sure.
