Q:

Visual Studio Express 2013 Web Site Administration Tool (WSAT)

I am trying to access the Web Site Administration Tool (WSAT) so I can manage the users and roles established by an earlier version of VS.  Apparently Microsoft took it away.  I have Googled a solution, but I am not successful.  
In the command prompt I entered... 
iisexpress.exe /path:C:\Windows\Microsoft. NET\Framework\v4.0.30319\ASP.NETWebAdminFiles /vpath:/WebAdmin /port:12345 /clr:4.0 /ntlm

I get an error...
c:\Program Files\IIS Express\iisexpress.exe is not a valid Win32 application. 

What could be wrong? 

A:

I repaired the IIS Express installation and it fixed the issue.  The file had a size of zero when I looked at it before the repair.
