@foroxian said in Reinstalling not working:
just that reddit thing looks like its for opera
The main examples are for regular Opera, yes. But, there are notes in there for Opera GX too. Some things there are implied. For example, if it says to delete the "Opera Software" folders, you wouldn't do that if you also have regular Opera installed. You'd instead just delete the "Opera GX Stable" folder in the "Opera Software" folders. As another example, if it says to delete all Opera uninstall keys in the registry, you would skip keys for regular Opera and delete just Opera GX's keys. As another example, you wouldn't delete "HKEY_CURRENT_USER\SOFTWARE\Opera Software" if you have regular Opera installed too. You'd only remove Opera GX-related stuff in it.
With that said, I'll have to make things a lot clearer on that Reddit page sometime.
Maybe https://www.revouninstaller.com/products/revo-uninstaller-free/ will be easier and allow you to remove all of Opera's traces so you can reinstall.
Note that you can uninstall regular Opera or get rid of all its traces manually without affecting its data and settings etc. as long as you keep the "Opera Stable" folder in "C:\Users\yourusername\AppData\Local\Opera Software" and "C:\Users\yourusername\AppData\Roaming\Opera Software". You can even back up (copy to a safe place) the "Opera Stable" folders just in case any uninstall utility you use wipes them out.

Make a test standalone installation to a folder named "Opera Test" on your desktop.
If that fails too, then I doubt your issue has anything to do with existing Opera file and or Opera reg keys laying around.

@foroxian You can try https://www.bcuninstaller.com/ instead of Revo to see if it helps.

You need to check and repair your system files.
Then, check your file system.
Then, check the health of your drive with CrystalDiskInfo.

Temporarily create a new user account on Windows (local one not tied to a Microsoft account), log into it, download Opera, run the installer to install Opera for that user and test how things work there.
That will tell you if the issue is with your user account or system-wide. You can delete that test account when you're done testing.

I'm having the same problem, and it happens every time Opera One updates. Last time this happened, I was able to fix it by deleting everything to do with the browser and reinstalling with the offline installer. This time, no luck.
I've run sfc /scannow, I've reinstalled all of my Microsoft redists, DISM /Online /Cleanup-Image /RestoreHealth, used safe mode and DDU to uninstall my GPU driver, then reinstalled fresh. My drive health looks fine, as CrystalDiskInfo says 90% good. Tried emptying the TEMP folder completely. Checking permissions on TEMP folder, etc. Even tried installing it with a temporary custom temp folder through elevated command prompt with no luck. I've tried the offline installer both from the link given when the online installer fails and downloaded directly from the Opera FTP website. No luck..
When I unpack the full installer exe with 7zip, the browser runs just fine. No issues there. It's the installer that won't work, and I just went through and installed 5 other browsers with no issues (Firefox, Floorp, Chrome, Vivaldi and Brave all install and run just fine). First, I was getting side-by-side errors saying to use sxstrace, but then after deleting everything related to Opera in multiple different folders, I started getting the corrupted .pak error.
The only thing I haven't tried is sxstrace, but I ran that last time this happened and it came back with no issues.
This is the only program I'm having trouble with. Other browsers install fine. Games run fine. No issues. Any and all errors in Event Viewer are to do with trying to install this browser and something blocking it and causing an access violation in ntdll.dll. Out of dozens of apps, this is the only one I have issues with. And the issues only started after I installed VS Studio and its corresponding SDKs, etc. I removed VS Studio, made sure my redists were repaired, but still having this issue.
Edit: I ran chkdsk, it found some errors and repaired them, ran sfc /scannow and restore health again after that, which came back with no issues, but still getting corrupted .pak error on install. Not sure what's going on. I think I've just about exhausted my level of expertise on this. One thing in the event viewer made it look like Opera One was running into some issues with my display driver as it was trying to install, which is why I reinstalled that.

@alphamachina Some Opera installer crashes, especially .pak corruption or ntdll.dll access violations, have been reported when certain Nvidia driver versions interact with Windows memory protections or graphics API calls during installation. Maybe Opera's installer doesn't like my specific driver version (I'm running a slightly older driver because Nvidia's latest driver is running like garbage in games and causing all kinds of issues.)
Have you guys seen any issues with Nvidia driver 577.00 in regards to Opera One?
