[SikuliX1.1.2 Offline Setup]there is no Main-Class definition in manifest file --- use 1.1.3

I tried offline setup for someone.
setup is complete, but I can not open SikuliX IDE.
Though actual errors are displayed in Japanese, Error say like "there is no main manifest".
[environment:]
Windows7
Java version "1.8.0_161"

I compare the new jar file with the past jar file.
