I can't package the project for android. Is it because of windows 7?

I can’t package any project for android. Always comes out error what apk was not found. I wrote about it in my previous question called ‘Launch failed! Failed to Install app. ExitCode=36. Android’ Link: Launch failed! Failed to Install app. ExitCode=36. Android - Mobile - Unreal Engine Forums
Can this error be because I am using Windows 7? Maybe it’s not supported anymore? Please tell me any suggestions…

SOLVED: Yes, It’s because I have windows 7!! I tried to package and launch on PC with windows 10 and all worked!!

This is because I have windows 7!!!

Apparently Epic Games stopped supporting windows 7. So, if you have this problem, upgrade your PC to windows 10!!
