Crystal, Installshied, OLE and all the problems

I tried running a web application delivered by a vendor. Crystal Reports began acting crazy. The vendor failed to deliver the right merge modules. So, I downloaded the redistributable, got the key code from the vendor (with an error and guessed the right one). The error message changed; after a number of hours of search, began downloading the service pack for Crystal 9.0.

The pain here is, the redistributable is about 25M and the service pack is 68M. After multiple aborted attempts to download and a final good download, I bump into an install shied problem where the error message indicates that the type library is not there!

It took someone with 15 years of experience with software to progress this far. Who said software makes life easy!
