I received several inquiries about installing VMRCplus in an unattended way. Most people were able to install VMRCplus that way but could not figure out how to install the Virtual Server COM API also.
Just for the complete picture I have outlined both installation options below.
To install VMRCplus using the defaults use:
msiexec /i vmrcplus.msi
This will install VMRCplus using the default location and without the Virtual Server COM API.
To install VMRCplus with the Virtual Server COM API use:
msiexec /i vmrcplus.msi ADDLOCAL=ALL
This will install VMRCplus as the previous step but also the Virtual Server COM API.
You can suppress any output by adding msiexec switches like /quiet /passive.
