I tried to create a different pathes to the file, but without success.
Same problem Unity 2019.4 with Playmaker 2018.3, thirtyfour CS2046 errors “The type or namespace name ‘iTween’ could not be found”
The problem with this is the errors cause Playmaker not to load up.
Tried doing as a fresh install and also the assets import method also no luck, has anyone found a solution?
