OctoWow - Forums

When clicking "play" on the launcher, I get one of two error messages:

VanillaFixes: Failed to create remote thread.
VanillaFixes: Failed to clean up process memory (pDllPath)

I have tried:

- Reinstalling
- Removing all addons
- Running the launcher as an Administrator
- Running VanillaFixes.exe without going through the launcher
- Disabling all mods, except VanillaFixes (game silently fails to launch without an error message - enabling VanillaHelpers causes the error message to appear again)
- Disabling all mods, including VanillaFixes (game silently fails to launch without an error message)
- Running WoW.exe without going through the launcher (game silently fails to launch without an error message)

OS: Windows 10
Launcher version: 1.3.8
Game version: 1.18.1 (7272)

I am also using Windows 10 and I have a similar issue whereupon pressing "Play" from the launcher, the game quietly fails without an error message. I get the same quiet failure from opening WoW.exe directly.

Hi,

I have a problem with the current OctoWoW client. The game does not launch at all and there is no error message.

My setup:
- Windows 11
- Game version: 1.18.1 (7272)
- Launcher: current version downloaded from the official website

What I tried:

- Downloaded the official wow-client.zip directly from the OctoWoW website (approx. 8.8 GB).
- Extracted it to a local folder.
- WoW.exe does nothing when launched directly.
- I also tried launching WoW.exe from CMD – it immediately returns to the command prompt without any message.
- ERRORLEVEL after launching WoW.exe is 0.
- I tried WoW.exe -opengl, with exactly the same result.
- WoW.exe does not even appear in Task Manager.
- I completely deleted the client and downloaded it again through the official OctoLauncher. The result is exactly the same: clicking Play makes the launcher disappear/reappear, but WoW never starts.
- Windows Defender has no detection for WoW.exe in Protection History.


The same problem occurs with both a fresh ZIP installation and a fresh installation downloaded through the launcher.

Could anyone confirm whether this is a known issue with the current client on Windows 11, or suggest what I should check next?

Thanks!

I've also tried with the .zip client download, and it's exactly the same for me on Windows 10.

Makes no difference for me.

Edit 31/08: Most recent patch seems to have fixed this issue.
