about ipcBeginProcess in Windows 7 64 bit machine

Hi,

has anyone have an issue with ipcBeginProcess? i have an exe program that need to be run from Allegro, running the exe outside Allegro does it job, but when calling it from allegro it does not work at all (not being called to be exact), is there an issue of ipcBeginProcess not working in Allegro win7 64 bit

i tried this ipcBeginProcess("notepad") and it is working and using ipcBeginProcess in an XP 32 bit machine is also working

*** shell is not an option since i need to run the exe without showing the cmd console window and I need to know when exe program finished its job

edit: using shell aside from the cmd console window was being shown the exe program was working

 thanks
