I believe waterfall relates to the gopro camera and software. Have you had gopro software installed on your computer then uninstalleld it? If so, reinstall it and try again. From what I've heard, uninstalleld gopro software also removes files it shouldn't and a reinstall puts them back.

This thread has the specific dll's you need too remove to eliminate the waterfall error caused by gopro so#tware. The gopro sostware continues to work aparently unaffected.

I uninstalled gopro restarted and the error message is still the same: No DLLs ware found in the waterfall procedure Now I still have a doubt I also uninstall avast?

Uninstalling the gopro software does not remove the offending dll's, you need to manually delete them. See the thread I linked to.
