I’m Getting the following message.

Cannot run program “” (in directory “C:\defold\branches\63136\37494\master”): CreateProcess error=87, The parameter is incorrect

Reading documentation it says that is a classpath error, I also have my classpath declared as C:\java\

Sorry, I think it is solved, I pressed the “Custom Application” by mistake I think, now it is unchecked and working.
