The previous version, 5.0.20182.28034, works without any errors at all.

Thanks.

I found & also replied on that thread yesterday :)

This is the last version that works with Windows XP. It is 5.0.20173.50948 (build date: 14-Dec-2017). Size is 7 MB.

http://web.archive.org/web/20180311210942if_/https://telerik-fiddler.s3.amazonaws.com/fiddler/FiddlerSetup.exe

All built on later do not work anymore, including:

5.0.20182.28034, 27.6.2018.
5.0.20181.14850, 20.3.2018.
5.0.20181.13826, 12.3.2018.

I also noticed that since that version there is kind of online installer that tries to download offline installer, although offline installer is found inside online installer, can be extracted via 7-zip. Luckily the windows xp compatible version installer does not try to download anything, but works just fine (standalone).
