    ComCtrl32.dll is an ActiveX control and on one machine only one version can be installed/registered; that's why it's called DLL-Hell: https://en.wikipedia.org/wiki/DLL_Hell

    According to MSDN Isolating Components and the SO thread, with ISOLATION_AWARE_ENABLED used, you need to save contexts which need to be isolated. Then you active the context before you call on each entry functions and deactivate the context after functions returned.
