Hi Erel
The issue went away. The only thing I did different to make it work was to put the project in it's own folder off the root of the drive, after that worked I could put the project anywhere. Very odd but perhaps some configuration file was corrupted and by trying to compile closer to the root it was corrected.
I think the indicator of this problem was the error msg saying the filepath or name was too large. So if anyone has this issue this work around fixed it.
Btw v3.6 compiles much faster and is more responsive in both compiling and downloading the last build well done!
Regards
Mark
