I can confirm that version 1.8c does not work when 3D coat is installed on a drive other than the C drive. I installed the applink with no problem on a pc with 3d coat installed on the c drive. When I tried to do the same on another windows 7 computer we have that has 3D coat installed on the E drive (since the ssd C drive is getting a bit full), the temp directory path field comes up blank in the app link rollout and the error, "No "+" function for undefined " is displayed for the line that has "tmp Root Exp file = tmp Files Path + "export.txt". Based on the forum messages, I have tried the following without any success:
Ran 3ds max as administrator both before and after install
Edited the file, Applink_3DC_settings.ini to contain a temp directory set up on the E drive
If I right click on the temp directory field of the app link dialog, I get another error to the effect that shell explorer.exe is expecting a string but is getting "undefined"..
However, as soon as I created a new Exchange directory on the C drive at C:\Users\[user Name]\Documents\ the app link works. This is irrespective ot the path specified in the .ini file , which still points to the E:\ drive location for the Temp directory. So the installed script apparently expects the Exchange folder to be only on the C:\Drive and doesn't allow/recognize an Exchange folder on another drive irrespective of the path specified in the .ini file. Anyway this worked for me, and I thought I would pass this along in case someone else finds it to be helpful.
Thanks for the useful script.
