I got the error when updating the Fiddler. The error message is below

Is there any workaround to get out of this issue to update fiddler without reinstalling it.

It sounds like the downloaded update was corrupt, either due to a problem on the network or on your disk.

You can just download the Fiddler installer from the website and run it again; it will upgrade your existing copy.
