VB-Registry

Problem : Unable to register some DLL files (e.g.,msjetoledb40.dll) in some systems.
Q: I am using VB-SetupWizard utility to create setup for my application which uses ADO 2.1. When I instal my application using the setup,it is installed but some DLLs are not registered(at the time of registering DLLs and OCXs) in some systems(PCs).If I try to registe those dlls using 'regsvr32',it gives 'Error Loading DLL file' message.Is there any technique to solve this problem ?

if your app uses ADO, you need to include the appropriate version of MDAC_TYP.EXE in your application. This will install the required ADO DLLs on the client machine.
