After working with the above customer, it was determined the cause
was some free virus software that had "quarantined" the perl.exe executable,
basically /removing it/ from the c:\perl\bin directory.
Apparently this software takes updates automatically, and the automatic
update is what made the error suddenly appear.
The solution was to limit the virus software from looking in the
C:\PERL and C:\RUSH directories, as well as others.
Keep in mind automatic updates can cause totally unexpected behavior
in production. Loosing a whole night of rendering is possible, since
auto-updates often like to happen in the wee hours when no one's looking.
