Heads-up on Mono 5.2+

[Scott]

A heads up if you're trying to run Fiddler on a Mac with mono 5.2.  Starting from Mono 5.2, the "mono"command defaults to 64-bit.  Use --arch=32 switch to 32-bit mode to run Fiddler.exe.  

 

mono --arch=32 Fiddler.exe

 

This threw me for a while as I'm not a mono user and Fiddler continually failed on start with the error below.

 

WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all

Oh! Nice catch! I was just updating Mono today to help a friend get Fiddler running, and that would have provided me some unneeded frustration.
