Error installing Oracle Database Client 12c: "OracleMTSRecoveryService Control Utility has stopped working"
The issue in my case was that a DLL file was missing that prevented "oramtsctl.exe" from running. I found when I attempted to run the oramsctl.exe manually from its installation folder. The missing DLL file was in the Microsoft Visual C++ Redistributable Packages, which I installed to solve the issue.
