FIR Compiler II - error: child process exited abnormally

[Altera_Forum]

Hello everybody!!! 

I'm having problems with my FIR Compiler II megafunction Dialog! I m getting a "error: child process exited abnormally" on the message box! And can't change my design or configure my filter! The finish botton will stay disabled. I was looking at some NIOSII-SOPC design examples and since then Im getting this error! Can somebody help me!? lg murillo

So!!!! there are 2 way to solve this problem! 

1) You need to reinstall your OS and Quartus II. or 2) Update your Quartus II to version 13.1! with older versions you still have the same problem!  Support from Altera told me it is a "..... this is a PC dependency issue....." !!  note: I got this error "child process exited abnormally" using Quartus 12.1 sp1 on a windows professional 64bits PC!  bye and hope it helps some one out there! tschüss
