Hi Erich,
the attachment is the project using the KDS IDE tools.
when I install the PE at the first time,the IDE run well and don't have the strange error. I also install the other version just like PE 10.3,PE10.4 and KDS, the error also happens.
So I check the path:Drivers\Common,I can't find the DeclareISR.prg.I don't know the reason.
Please help to check it.
Thanks!!
