vvvv takes ages to open

As antokhio reported in this thread there seems to be an issue with Windows Defender causing those delays on some PCs. Go to Windows Defender > Settings > Exceptions and add your vvvv directory as an exception.

A virus scanner says that vvvv is a virus. Is that so?

Almost certainly not! Most likely your scanner complains about WinLockDLL.dll which is used by Styx (Windows).

Error Message: "The application failed to initialize because d3dx9_30.dll is missing. Reinstalling the software might solve the problem"

Sorry for that ugly error-message.
Please run setup.exe where you should be notified of a missing DirectX9 installation. Best download and run the WebInstaller which should solve the problem.

Even if you have DirectX 10/11 (on Vista/Windows7) you'll have to install DirectX9.

vvvv shows up in the task bar, there may be a DirectX Renderer, but there is no patch window

  • Have you run setup.exe at least once as Administrator? Even if you are admin try to rightclick setup.exe and "Run as Administrator".
  • Are you using Windows 7 and running VVVV out of the c:\Program Files folder? There might be a user rights issue with registering Plugins (at least in Beta 24.1) - try putting your VVVV folder at an unprotected location like your desktop and try running as administrator again.

The Renderer's Window is gray

This is almost certainly a graphic driver problem. Make sure you have its latest version installed or even cosider a graphic card upgrade if the problem persists.

Cannot start VVVV: OMP abort

Read this thread.

My patch has some bugs and/or Red Nodes

Read Debugging.

I have dropped frames when writing to external USB drive

Try disabling "USB selective Suspend " in advanced power settings in Control Panel -> Power Options -> Change plan settings -> Change advanced power settings -> USB settings

Helpful Methods


Start vvvv with the Commandline Argument /logstartup.

Use this if you have troubles starting vvvv. With this flag vvvv logs all steps it does on startup into a .txt file, placed next to vvvv.exe. You can then post that textfile to the forum and we'll see what we can do.

Renderer (TTY)

Always use a Renderer (TTY). This is also vvvvs error console so it may provide some information you could post in the forums.
