I need to have ability to start program by the file name on Windows 7 like firefox.exe. But nothing from this thread works. ie Notepad++ creates an entry in App Paths but still command prompt is unable to launch it.

For sake of testing, I copied notepad++.exe in System32 and then it could start from command line.

So it would seem that Windows/command line ignores/fails to see the PATH enviromental variable and App Paths registry.

PATH entries:

C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Broadcom\Broadcom 802.11;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\MATLAB\R2015a\runtime\win64;C:\Program Files\MATLAB\R2015a\bin;C:\Program Files\MATLAB\R2012a\runtime\win64;C:\Program Files\MATLAB\R2012a\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\;C:\Program Files (x86)\AMD\ATI.ACE\Core-Static;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\; C:\Program Files\Java\jdk1.8.0\bin;C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\; C:\Program Files (x86)\Notepad++\

  • Excuse me, but have you bothered to read the question or just marked after seeing the title? I specifically mentioned that that thread doesn't help. Please remove the duplicate marking – Andrey Pro Nov 29 '15 at 23:34

    Notepad++ work perfectly well if you add it to the path. If you think the other question isn't a duplicate please edit your question and say why. Tell us exactly what didn't work. – DavidPostill Nov 29 '15 at 23:37

    You have provided no diagnostic information, for example what is in your PATH, and your registry App Paths. – DavidPostill Nov 29 '15 at 23:40

    Please also read How do I ask a good question? – DavidPostill Nov 29 '15 at 23:42
  • Exactly, it should, but it doesn't, neither Firefox, neither anything else. I thought i made it clear. I have no idea what is needed. I will add PATH list shortly, but nit sure how to post registry App Paths. it's a long list – Andrey Pro Nov 29 '15 at 23:50

Remove the space before C:\ from the last entry in the PATH ; C:\Program Files (x86)\Notepad++\.

The above should fix the Notepad++ issue. For other programs, post their exact location, and the related entries in the PATH or App Paths.


[ EDIT ] When starting programs that are registered under App Paths (but not in the PATH environment variable) one must explicitly use start.

For example, just notepad++ will give a not recognized error at the cmd prompt, but start "" "notepad++" (or simply start notepad++ if the name contains no spaces or other special characters) will run the .exe from the location in App Paths.

  • Yes that helped thanks. But that shouldn't have been neccessary because notepad++ has entry in app path. exported app path subtree and added to the first post. These entries were created by installers and the paths of the application correspond to respective entries, so actually there is no good reason they wouldn't work. – Andrey Pro Nov 30 '15 at 2:09
  • @AndreyPro I guess you are not using start , see my edit. This is why it helps to provide all relevant details upfront. – dxiv Nov 30 '15 at 2:19
  • I mentioned in the post, that i would like to start simply by name. And also the answer in the linked post tells that no start needed fo app path – Andrey Pro Nov 30 '15 at 3:28

    You said start program by the file name. The answer is start notepad++. You also said that nothing from the linked thread worked for you, yet the question itself being asked there was have tried the command line START any_program.exe, but .... Anyway, I take it that you've got it working now. All is well which ends well, only it tends to end sooner the more complete the question is to begin with. – dxiv Nov 30 '15 at 3:36
  • @AndreyPro P.S. You have a point that the accepted answer to the other question does not make the distinction between start and direct execution at the cmd prompt. I just posted a comment there to clarify, not that I think many will read it 3 years after the fact. – dxiv Nov 30 '15 at 4:12
