Really weird behaviour on my system. I can execute xilperl.exe in the following way on my system:

C:\Xilinx\10.1\ise\bin\nt>xilperl.exe

In order to make things easier I do not wanna add the whole path to execute xilperl, so I added the "nt" directory to the PATH variable. Here you can see the content of PATH:

echo %PATH%
C:\Xilinx\10.1\EDK\bin\nt;C:\Xilinx\10.1\EDK\lib\nt; C:\Xilinx\
10.1\ise\lib\nt; C:\Xilinx\10.1\ise\bin\nt

So you can see the appropriate directories should be set, however, when trying to execute xilperl it is still not recognised:

C:\>xilperl
'xilperl' is not recognized as an internal or external command,
operable program or batch file.

Anyone an idea what could go wrong here, I can't see what I missed.

Try removing the spaces in the PATH variable. –  Ray Toal Aug 8 '11 at 14:19

I don't think you are allowed to have spaces before or after the semicolons in your PATH. Remove the spaces and try again.

Indeed, that's it. Thank you so much, removing the spaces did the trick! –  Rob Aug 8 '11 at 14:38

You are missing the ending backslash in your paths You could try using backslashes :

C:\Xilinx\10.1\EDK\bin\nt\;C:\Xilinx\10.1\EDK\lib\nt\;
C:\Xilinx\10.1\ise\lib\nt\;C:\Xilinx\10.1\ise\bin\nt\

Spaces could also be a source of problems.
