@burnout426 @donq @blackbird71 @leocg Ok guys so hear me out! I installed another uninstaller the ''Bloatware Uninstaller''. It even deleted files from registry. After that I restarted my PC and installed the offline package. And everything's ok now. At least for me. Thanks for all of your help.

@burnout426 @donq @blackbird71 @leocg Solved Version 2!!! I tried to install Opera to a brand new Laptop (Windows 10) and for some reason it did the Exact same thing! The pop up messenge ''This opera installer works only on Windows 7...'', windows 7 icons (-,❒,X) etc.

What I did is I Installed an older version, the ''69.0.3686.95'' worked for me (the others caused the same problems for some reason) https://get.geo.opera.com/pub/opera/desktop/69.0.3686.95/ and it worked Perfectly! Then I went to settings and all I had to do was to update to the latest version.

I have no idea why Opera does this. I really don't and my only geuss is that something has to do with Windows 10? Maybe idk.

@burnout426 I have the ''Microsoft Windows [Version 10.0.19043.1288]''. Maybe I'm going to delete it manual if I can't find a better way.

@burnout426 I tried that crazy way you told me, also I install the offline package and nothing changed. It's like I never did anything. Literally when I opened the opera after the clean instalisation (and after I delete al the files from the registry) my last pages were open. What the freak!!?!? It's like I never unistall it man! I'm going crazy right now. What is going on?

@leocg Well. I have one and did nothing. I'm using the iObit uninstaller. Same thing with windows uninstaller. Maybe I'll try yours. But then again... let's just say that I managed to uninstall it. The problem is that when I istall it again it will be the same think.

Every time I open my Opera Browser, a notification comes from an application called installer.exe that says "This opera installer works only on Windows 7 or higher. visit www.opera.com to download compatible version" The opera is opening, but every time I want to open it. I'm using a Windows 10 PC. Also the top right corner of my Opera window has the oleder windows 7 icons. I'm talking about the Close, minimize and window buttons. And I can't uninstall it only to delete it. But when I delete all the files from Opera and install it again from the opera.com still same thing. I'm in a loop guys I need help! What is going on
