Win 10: Open pdf files with Sumatra - pdf assignment to open with Sumatra out of service

[ritter-gut]

Hy there,
on my laptop win 10 pro 64, Firefox Browser ESR I was running Sumatra pdf reader 64 bit with installation since 3.45, I can't open new downloaded pdf files from the Browser. System repairing by dism and sfc, no error's. I found the downloaded files.pdf "Sumatra-Icon- labeled", so it was strange, that the file could not be opened and only the error message box appeared with advise, set and conncect the file to a standard system app or install an app to open. ?? That I've multipled done, the pdf was assigned to sumatra as standard system, but new files could only be opened by rightclick "open with - selecting sumatra", but not by doubleclick on the pdf-file. The always open pdf with sumatra checkmark didn't work, too

Solution: I installed the sumatra 3.5 experience under "programme files" and linked the requested assignment by search "open by other apps or program"s to that installed sumatra icon in the program folder on my computer.

Now everything runs with doubleclick as expected. I think, here at the sumatra forum sw-developer have much more experience than me a simple user, but it seemed to be - ask google-, that sometimes some people have problems in opening pdf files, what does not mean, that there is a possible bug or only a feature. :-)

Thanks for reading and best regards from ritter-gut
