Executable not found despite PATH variable correctly set

Question

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.

Answer 1

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

Answer 2

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.
