Could not find active.txt

[Jerry]

I get an error while loading fiddler (attached screenshot).

Could not find file "<install directory>/active.txt"

Same issue.

Hi guys,

Could you share something more about this problem? Does this happen on the first run of Fiddler? Does the user that runs Fiddler have write permissions to the Fiddler folder? Have you somehow modified the files in Fiddler folder?

Yes this happened on the first run and all future runs.  The user has full permissions.  I actually tried chmod 777 to the whole directory and still the same error.  I did not modify the files in the fiddler directory.

Thanks,

Hello,

Could you please unzip and copy the attached file to Fiddler folder and start Fiddler wit this command 

mono --debug Fiddler.exe

Then, please, copy the exception stack trace here.

The attached file did not execute properly.  See output:

$ mono --debug Fiddler.exe
Cannot open assembly 'Fiddler.exe': File does not contain a valid CIL image.

 

When I try the same with the original Fiddler.exe I get the following output:

$ mono --debug Fiddler.exe
/Users/Shared/fiddler-mac/getActiveServices.sh: line 23: [: Thunderbolt: binary operator expected
Could not find current service
/Users/Shared/fiddler-mac/getActiveServices.sh: line 23: [: Thunderbolt: binary operator expected
Could not find current service

 

I am using a Thunderbolt Monitor if that information is useful.

Thanks,

Interesting, I too am running a Thunderbolt monitor and get similar results but my error is "Display:" instead of "Thunderbolt:".

Running macOS 10.12 if that helps too.

Hello,

Thanks for bearing with me this far guys. 

You are not supposed to execute the attached file. You just have to put it in the same folder where the rest of the files are and start the original Fiddler.exe with the --debug option.

However, the logs you sent me actually helped diagnose the potential problem. I prepared a build with the fix and you can find it attached. Please, let me know how it works for you.

That fixed it for me too!

Thanks, Tsviatko!
