VRChat crashing? Not launching? There's a few things we can try right off the bat to see if you've got something easily solvable. Follow the steps below and we'll see how it goes.
Press your Windows key and type "cmd" into your Windows Search bar. Right click "Command Prompt" and click "Run as Administrator". A black command prompt window should pop up. Copy this command with Ctrl-C, and paste it into the window by right-clicking in the window.
rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\Cookies && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\HTTPCache && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\Unity && rmdir /S /Q %AppData%\..\LocalLow\VRChat\vrchat\VRCHTTPCache && rmdir /S /Q %TEMP%\VRChat && REG DELETE HKCU\Software\VRChat\vrchat /va
Press Enter. A bunch of files will show as being deleted. It will then ask you if you want to delete all keys under the VRChat key. Press Y for Yes, and press enter. Close the window and skip to the Final Steps section.
If you got any errors, please continue into the Manual Method section.
First, let's clear your cache. You can clean cache by deleting the folders within
C:\Users\[Your Username]\AppData\LocalLow\VRChat. AppData is a hidden folder, and you may have to enable visibility of hidden folders in Windows Folder Options. The easiest method to find this folder is by pasting this into your Windows Explorer address bar:
In that folder, delete all folders, but don't delete any text files!
Now, let’s clear VRChat settings (PlayerPrefs). On Windows, open the regedit app and delete
HKEY_CURRENT_USER\Software\VRChat\vrchat. Please be careful when editing your registry, this can potentially damage your computer.
Finally, paste the following address into your Windows Explorer address bar:
Delete the vrchat folder in that folder.
Once you've done either method, try opening the Properties for VRChat in Steam and choose "Verify Integrity of Game Files" under the local files tab.
Ensure that you are running the latest version of Windows, and that your GPU drivers are up to date. Please note that we do not support the Insider Edition of Windows 10.
Also, if you're getting crashes, try using a different headset or audio device. Some USB headphones/headsets are known to cause crashes. This is not a VRChat bug, but unfortunately a Unity issue. It will be fixed in a future upgrade to a new Unity version.
Finally, please whitelist VRChat.exe in your antivirus program and any firewalls you might have running. If you can't whitelist the application (or if it doesn't appear to work), try disabling real-time protection on your antivirus and your firewall while you play VRChat. Don't forget to turn it back on!
If you're still having issues, please reply to this email with your logs. Here's how to find them:
Let's grab your output log. You can find it at
C:\Users\[Username]\AppData\LocalLow\VRChat\vrchat\output_log.txt, or by copying and pasting this into your Windows Explorer address bar:
Please attach the output log to your ticket. Don't copy and paste the contents, attach the text file!
Also, if you have any error folders in your VRChat folder (
C:\Program Files (x86)\Steam\steamapps\common\VRChat) please include those as well. They are typically named in a format like this:
2017-08-01_195906. Please do not try to send your VRChat_Data folder!
It works best when you ZIP all of the files up. I appreciate your patience in doing all this! Many problems are addressed by these steps, so I encourage you to follow them closely.
