************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

According to the provided stack trace it seems that the Calibri Bold Caps font style Italic is not installed on your machine. Could you please give us some more details how exactly you obtained this error? Which is the Telerik control that you are using with this font? What is the operating system on your device?
Once we replicate the error locally, we would be able to make an adequate analysis of the precise case and assist you further. Thank you in advance for the cooperation.
I am looking forward to your reply.

hi, I am using "Win Ultimate 7 SP 1" and "Fiddler 5.0.20182"
the error occurs when I press "any process" which I want to use to see traffic from a specific process.
here is a picture: https://i.imgur.com/FDo88W4.png
Also, if it helps you I am using a custom theme for my Windows to make it Dark and system fonts where changed by the software.
As noted in the Font 'Tahoma' does not support style 'Regular' troubleshooting documentation, installing a theme or application may cause something like this. I recommend the following steps to troubleshoot this.
Step 1 - Ensure that the font is installed at C:\Windows\Fonts or open Control Panel -> Appearance and Personalization -> Fonts
Step 2 - If the font is installed, get the full name of the font file from the installation, C:\Windows\Fonts\[FontFileName]
Step 3 - Verify the registry is referencing the correct file name.
Step 3a - Open Registry Editor with regedit.
WARNING: Making incorrect changes to your computer's registry with regedit can cause serious, system-wide errors that might require a complete OS re-install. Use the Regedit.exe tool at your own risk.
Step 3b - Ensure the registry references the same file name from the installation. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
If none of the above works, I recommend changing the Windows theme and trying to capture traffic that way. It could be that the font wasn't designed with italics.
I hope this helps. Let me know if you have any additional questions. Thank you for using Fiddler.
