WAD cmd.exe under tcc doesn't find apps

[noahcoad]

Seen this before? Could there be some setting I have wrong in TCC? Hoping it's not a bug.

1. Run tcc
2. From prompt run cmd
3. Try to run a program found in directory or path without specifying file extension
Expected: runs
Actual: error msg

This is breaking running other 3rd party batch scripts that call cmd.exe to run apps, like the nodejs npm module. Running cmd.exe from Start > Run works fine, finds apps without specifying extension, error occurs only when cmd is run from within tcc

Hi,
No problem here, but I am running a newer release than you are. I am on 32-bit OS.

Have a look at CMD's %PATH%. Could "Win64 File System Redirection" (OPTION\Startup)have anything to do with it?

Not reproducible here.

This is definitely not a TCMD or TCC issue -- unless you've found a catastrophic bug in the Intel hardware and the Windows OS security model. The parent process does not (cannot!) affect the child process's file search & execution behavior; CMD is talking straight to the Windows APIs and TCC is totally uninvolved. (Unless you're running plugins that are intercepting APIs?)

It's far more likely that you've got a different environment / registry / etc. configuration in the native TCC window vs. the CMD window. Try starting a CMD window, then run TCC, then CMD, and see if you get the same behavior.

Found the issue. In my tcstart.btm I had a line like this to add some extensions to the executable paths:
set pathext=%pathext%,.py,.rb
Worked fine in TC, but when dropping to cmd.exe from TC, cmd.exe got overwhelmed. Removing the %pathext% fixed the issue. Thanks to everyone for quick and thorough replies.
