Make VMware Workstation 14 and VIX COM API work together

After installing newest VMware Workstation 14, it turned out that the automation API stopped working with the following error

Retrieving the COM class factory for component with CLSID{COMPONENT-ID} failed due to the following error: 80040154 Class not registered(Exception from HRESULT: 0x80040154(REGDB_E_CLASSNOTREG)).

It seems that the newest version does not install two important COM DLL files (and consequently does not register them): VIXCOM.dll and VIXCOM64.dll. The solution is to copy them over from older installation and register them (as administrator):

regsvr32.exe VIXCOM.dll
regsvr32.exe VIXCOM64.dll

Things start working after this little trick. Alternatively, a full VIX API 1.15 has to be installed (it is available as a separate download from VMware support pages).

The problem has been tackled by our support and is described here

Note: Since both DLLs can be freely distributed, you can download them from the above link in case you don’t have older installation of VMware Workstation.
