Fatal error on launching the app.

[Jellybeans❤]

as the topic states. since the recent update whenever i try to launch the app it goes into a immediate crash stating nothing but Fatal Error! tried reinstalling. reupdating drivers and deleting settings folder.

Sorry for the issues. I'm not sure why some people run into issues with the updates, but I think you should be able to fix it by deleting this folder:
C:\Users\UserName\AppData\Local\HereSphere\Saved\SaveGames (replace UserName with your info).

You can first try just deleting the Default.sav file in the folder. If that doesn't work, then you'll need to delete the Default folder as well, which will delete your saved video settings. If you want to try to preserve the saved video settings, try copying the Library.hsl file in the Default folder to another location, though the Library.hsl might be corrupt, which is causing the crash.

If that still doesn't work, try deleting the the "HereSphere" parent directory, and reinstall HereSphere. Let me know if none of those solutions work.

I have this issue starting recently (after a complete new OS and SteamVR re-install).
Only...it crashes on first launch every time, so there is no Local\HereSphere folder to delete...
I've uninstalled and reinstalled, with a restart in between. Same symptom.

Can you double check that the directory: "C:\Users\UserName\AppData\Local\HereSphere" doesn't exist? Make sure to replace "UserName" with your actual user name. If you updated your OS, the files might still be there.

If I understand correctly, you installed a new OS and the issues are now occurring? Can you provide the error message you're receiving? Have you tried reinstalling all of your drivers (especially your graphics drivers)? And also try uninstalling and reinstalling HereSphere. Let me know if the problem persists.

Thanks for the quick reply. Since I have SUCH a common name (and it's on my steam profile!), it won't hurt anything to tell you that Users\jon\AppData\Local\HereSphere definitely does not exist. :)

Launching it by hand from the install directory barfs with a modal dialog complaining about XAPOFX1_5.dll

Googling around for that error, then installing DirectX from the Runtime Web Installer from Microsoft.com didn't resolve it.

The new OS install might have wiped out some dependencies. Try running the UE4PrereqSetup_x64.exe file located in the HereSphere steamapps folder:
steamapps\common\HereSphere\Engine\Extras\Redist\en-us

If that doesn't work, try installing the DirectX stuff from here if you haven't already: http://www.microsoft.com/en-US/download/details.aspx?id=35

Seems like it might be missing DirectX9 libraries.

This thread mentions uninstalling the UE4 prerequisites and Microsoft Visual C++ Redistributables and then run Steam to let it trigger the correct UE4 installer: https://steamcommunity.com/app/468160/discussions/2/1290691308579014796/

Man, NOOOTHING is fixing this.
Did all that and even went to the trouble to get a friend to drop me HIS XAPOFX1_5.dll from his Windows/System32 folder and I get the same error.

Are you running windows 10 or 11? Also 32 bit or 64 bit?

It could be your DirectX files are corrupt and preventing the installer from overwriting them. See if you can try repairing them:

This thread mentions manually deleting some of the problematic DirectX files: https://answers.unrealengine.com/questions/104748/packaged-game-will-not-launch-error-code-0xc000000.html

You can try using the Dependency Walker to pinpoint the exact DirectX file that's causing the issue, rename/delete the file, and then run the DirectX installer again to replace the file with a new version. This thread has step-by-step instructions on how to do it: https://answers.unrealengine.com/questions/12975/unreal-engine-wont-launch-error-code-0xc000007b.html

Let me know if you need any help completing these steps.

AHHHHH! I finally traced it down to something hinky with DirectX in general when I reinstalled Wreckfest and it would not launch either.

All the attempts to install DirectX components via dxwebsetup and directx_jun2010_redist exes weren't fixing it because it would spot the file and....fail to replace it.

I straight up deleted XAPOFX1_5.dll D3DCompiler_33 to 46 (which is what Wreckfest was complaining about) then used the dxwebsetup exe and... voila!

I know it's not a *common* error, but definitely add "rename the named *.dll file to *.dll.old and install the DirectX packages again. If it works, delete the *.dll.old file, it was corrupt." to the troubleshooting toolkit!

Thanks for sticking with me, [developer] :)

Awesome, thanks for reporting the solution. I'll add it to the troubleshooting steps.
