Mumble installation failure - Error code package 2503/2502

Good evening! ;)

First of all, I'm new here so I apologize in advance if I'm not asking this question in the right section... :/

So here's the problem, I just upgraded to Windows 10 (my hard drive failed and the repair guys upgraded me to W10) and I downloaded Mumble 1.2.10 from Filehippo (https://filehippo.com/fr/search/?q=Mumble. I reached the download window, opened "mumble-1.2.10", clicked "Next" for the first time, accepted the terms of the license agreement, clicked "Next" again and then I arrived at the "Custom Installation" window where a detail seems odd to me:
(the little red cross next to "murmur (server)").
But anyway, I clicked "Next" then "Install" and it loads for two seconds and then shows me the "mkrautz.dk - do you want to allow this program to make changes blah blah blah..." and then the two error messages (error code 2503 and then 2502) and it says that an error has caused the installation wizard to finish...
I have therefore searched for solutions on the Internet regarding this problem and wanted to try to find explorer.exe in the task manager but I can't find it, so I skipped that step and did "File" -> "Create a task" (explorer.exe, create task with admin privileges) and it sent me to my documents. :/

Do you have a solution?

Thanks in advance :)
