I have recently been decommissioning Lync 2010 FE Server but ran into a weird issue where Removing Components from the Deployment would fail at the stage of removing mcxstandalone.msi as per the error message below.
Removing McxStandalone.msi(Feature_WebComponent_Autodiscover)..failure code 1603
Error returned while installing McxStandalone.msi(Feature_WebComponent_Autodiscover)..failure code 1603
I can confirm the McxStandalone.msi existed in C:\ProgramData\Microsoft\Lync Server\Deployment\cache\4.0.7577.0\setup but Deployment Wizard was just unable to remove this component from the FE. The only way to remove this component in the end was to Run the .msi and use the “remove button”
Thank you for reading
