Error: 'No DLLS were Found in the Waterfall Procedure'

Have you installed recently GoPro Studio software ?
Best would be to contact GoPro support team for assistance on this matter.

An alternative approach is to browse in folder: C:\Windows\SysWOW64 and then remove these files:

If you have a 32 bit version of Windows, the files may be found in the system32 folder.

ippcore-6.1

ippj-6.1

ippjw7-6 .. 1

IPPS-6.1

ippvc-6.1

This solution should fix the "No DLLS were Found in the Waterfall procedure" error, but it will have the side effect of causing Time-lapse sequences not to import.
Perhaps you can even keep these files stored elsewhere temporarily if using other apps and add them back if you are doing Time-Lapse.
