max/msp 8.1.8 standalone app not working

Hi Mario,
It seems that your did not include the externals and or other patch files in the app, when I was trying things out I discovered that the best way was to select the main patch and go [File] => [Build Collective] there you add all the externals you are using in you app, if you don't do it with the build script you have to add all the externals manual ( not very efficient ) However if you did all that then perhaps it could be a search path issue ( I believe it is a setting in the standalone object not sure though) hope it helps. If not, I hope someone else will have an answer.
