On a 64 bit Windows 7 machine, I've noticed that the various command prompt shortcuts installed with ifort all invoke their startup batch file using "C:\Windows\SysWOW64\cmd.exe". This means that the resulting instance of cmd.exe is the 32 bit variant, which is then subject to the various filesystem and registry redirections that come into play when hosting 32 bit apps on a 64 bit system.
Is there a particular reason for this?
The difference between the two cmd.exe's is perhaps inconsequential (and this is only relevant to the command processor, not executables invoked from that processor), but there is the odd windows system utility that becomes unavailable as a consequence.
