OAM webgate 11.1.2.3 crashes IIS 8.5 (Win 2012 R2) and a resolution to IIS webgate installation def

Hello everyone:

I would like to

A) share a solution to a defect I found in the 11.1.2.3 webgate for IIS on Windows Server 2012 R2

and

ask if anyone knows a solution to another issue I am facing (webgate crashing IIS with "Invalid Instance directory").

A) Here is the defect and the solution

The configuration script ConfigureIISWebGate.bat for IIS OAM webgate 11.1.2.3 does not treat the spaces in the web site name correctly. The configuration script first removes the enclosing quotes from the command line parameter for the IIS web site name and then omits to add them where they are required.
