Error installing Oracle Database Client 12c: "OracleMTSRecoveryService Control Utility has stopped working"

Question

The installation of the "Oracle Services For Microsoft Transaction Server" component fails when I attempt to install Oracle Database Client 12c (12.1.0.2.0) on Windows Server 2012 R2.

When installing that component, I first get an error that oramtsctl.exe has crashed:

Immediately afterwards, I get the error message "[INS-20802] Oracle Services For Microsoft Transaction Server failed.":

It seems that "INS-20802" is some sort of catch-all error, as none of the solutions I found were applicable to the problem. Usually the issues at this point were that the Control Utility isn't found. In my case it is found, but crashes when started.

This is the relevant information from the install logs:

What might be the issue here?

Answer 1

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.
