Controls Missing After Removing Program

[Super Dave 123]

I had created a program that consists of many controls that were purchased from a vendor. I compiled the program and installed it in the same machine as the one that has the Visual Studio. When I remove the compiled program, some of the dll files for controls are removed with the program. When I open up the Visual Studio, I can't gain access to those forms that use these removed controls because Visual Studio can't detect the dll files for those removed controls. How can I prevent the compiled program from removing those dll files for controls used by Visual Studio? I don't want to reinstall the controls every time I uninstall the compiled program that uses those controls.


Thanks.
