What exact version number of AE do you have? Is it 188.8.131.52?
What are your preferences for the exe path?
Nobody can tell you anything without proper system info or other technical details.
I have the 184.108.40.206 version after effects CC 2014.
The exe path are correct in the preferences.
And I'lm working with Windows 7 SP1
I have done a 3D form layer and exported it as a maxon cinema 4D module (.c4d)
Then I import the c4d file in my composition. All is okay.
But when I try to modify it with cinema 4D, it does'nt work. (I use the edit menu and do "modify original")
I've got this message : "Aucune installation de cinema 4D n'a été trouvée" (no install of cinema 4D found)
I have verified the exe path, they are both correct in the preferences.
Do you have an idea ?
Thank you !
