I've tried to use LaunchAppAndWait like so:
LaunchAppAndWait(SRCDISK ^ "MySetup.exe", "", WAIT)
but that doesn't work, the function fails and returns -1.
I've made sure that MySetup.exe is located in the same folder as the setup program (Disk1) so it should be able to locate the EXE fine.
Anyone know how to get this to work?
