ok, i had already try it, but it didn't change.
recently, I installed crystal report in this machine, and i installed after MDAC_TYP, it works correctly.
If that is the answer then ok but if you need to deploy to other machines I don't think you will want to buy Crystal for all machines or even if you could there are users you don't want to provide full Crystal access to.

Apparently you were missing one or more DLLs.

Look at the following link to check if you had installed all required DLLs.
