<![CDATA[Installation fails with ownerless file "opera.exe".]]>Every time i use the installer, portable or not, the installer fails to extract and leaves "opera.exe" in the "71.0.3770.287" folder. I can not delete, rename, or move this file. And every method i try fails to give me ownership of it. I am downloading the latest installer from the official website.

So when i try and copy it over, the opera.exe file becomes ownerless and 0-byte.

It doesnt show up in programs and features because it never finishes installing.
Clearing the temp files did not work either. Im honestly confused why this is not working.
And i dont have an antivirus to interfere with it.

Delete all files and folders in "C:\Users\yourusername\AppData\Local\temp".

Delete "C:\Program Files\Opera GX" if it still remains.

Delete "C:\Users\yourusername\AppData\Local\Programs\Opera GX" if it still remains.

Delelte all files and folders in "C:\Windows\temp".

Unpin and delete any Opera GX shortcuts you have.

Open up regedit and delete the "HKEY_CURRENT_USER\SOFTWARE\Opera Software" key.

Download https://ftp.opera.com/ftp/pub/opera_gx/71.0.3770.302/win/Opera_GX_71.0.3770.302_Setup_x64.exe and https://ftp.opera.com/ftp/pub/opera_gx/71.0.3770.302/win/Opera_GX_71.0.3770.302_Setup_x64.exe.sha256sum. Open the latter with a text editor to see the sha256sum for the installer. Then, check the sha256 hash of "Opera_GX_71.0.3770.302_Setup_x64.exe" to make sure it's correct.

Once you're sure the installer file is in tact, launch it, click "options", set "install path" to "C:\Program Files\Opera", set "install for" to "all users", uncheck "import data from default browser" if it's checked, adjust other options and install.

If that doesn't work, create another user on Windows and try doing an all-user install there just to see if it works.

Also, test to see if your anti-virus is interfering.

  1. C:\Users\Pa Cyber
  2. C:\Users\PACYBE~1

Maybe it doesnt work when your Username contains a blank space?
You could try installing it for "all users" instead (choose "options" in the very first window after starting the installer).

I tried the portableapps.com portable installer, the official website installer as portable, and not as portable. All of them had the same error with the ownerless file.

I ended up rolling back my PC to remove the files, but I would still like to be able to use the browser.
