I experience a very strange problem. I have the following path variable.

%SystemRoot%\system32\WindowsPowerShell\v1.0\;C:\Python27\;C:\Python27\Scripts;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Lenovo\Access Connections\;C:\Program Files\ThinkPad\Bluetooth Software\;C:\Program Files\ThinkPad\Bluetooth Software\syswow64;C:\SWTOOLS\ReadyApps;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Users\Robert\AppData\Roaming\Python\Scripts;C:\Windows\system32\WindowsPowerShell\v1.0\;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Lenovo\Access Connections\;C:\Program Files\ThinkPad\Bluetooth Software\;C:\Program Files\ThinkPad\Bluetooth Software\syswow64;C:\SWTOOLS\ReadyApps;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files (x86)\Git\bin;C:\Users\Robert\Programme\youtube-dl;C:\Users\Robert\Programme\sqlite

With this variable all goes fine and I can executes commands such as sqlite. However, once I append ;C:\Users\Robert\Programme\FFmpeg\bin to it I cannot run any command that is on that path anymore, such as sqlite.

Does anyone have an explanation for this behaviour?

Regards

I was tempted to blame the maximum length, but since you are on Windows 7, that should be 8191 characters. The current path appears to be about ~1400 characters. Ref: support.microsoft.com/kb/830473 –  Zoredache Apr 16 '12 at 22:28

Does Windows handle duplicate command conflicts? Maybe that is somehow triggering the issue. –  iglvzx Apr 16 '12 at 22:38
    
I deleted all the double entries which somehow seemed to resolve the problem. Regards –  orschiro May 22 '12 at 12:37
    
@orschiro: why not put your last comment as answer and flag it? –  superjos Apr 11 '13 at 15:06
