Registering a4wcrinterop.dll is failing

SOLVED

When trying to register the "a4wcrInterop.dll" file using the command below, the process fails with the message that operation has failed. Apparently it does not recognize the "/register"  as per the message below. Even when I type the command, the "/register" is highlighted in yellow to indicate that it's not a recognized command.

You must provide a value expression following the '/' operator.

"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe" /register "\\192.168.1.101\Sage2\Sage300\Runtime\a4wcrInterop.dll"

This is a Windows 10 Workstation.

How can I resolve this problem?
