Solve DLL Hell issue?

[nbchau]

Could someone please help?
My application uses two third party tools A and B. But the third party tool A again uses B. When installing A, it deploy a B's dll into System32. My app deploys the B's dll to a private folder. But when runing Windows always load the dll in System32. How can I solve this issue without overrting the dll in System32 folder?
Thanks so much!

Your application and tool A need to agree on where tool B is to be installed. I suggest you not deploy the B dll in the private folder. Just use the one deployed by A into the System32 folder.

If your application needs a newer version of the DLL than tool A, simply overwrite the B dll when your application is installed. If tool A needs a newer version than your application, don't overwrite it.
