Thank you for your message. Your feedback really helps us make Fiddler better. We are sorry to hear that you experience issues with it.
Firstly, I want to inform you that Fiddler does not require administrative privileges to run.
In order to solve your issue, we would need some addition information:
- Could you, please, let us know which older version you tried.
- We also need to know what .NET Framework version is installed.
- And last but not least, if there are any third party Fiddler Extensions (plugins) installed.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
