If there's no PATH variable ...

... does TCC still check the "App Paths" key? See this thread:

No. TCC will search the current directory (or the explicit pathname) only.

But if PATH is set, even to something bogus, then "App Paths" will be searched ... odd!

v:\> unset path

v:\> which excel
excel is an unknown command

v:\> set path=;

v:\> which excel
excel is an external : L:\OFFICE~1\Office14\EXCEL.EXE

So?

If PATH isn't set, then "App Paths" is the least of your worries.

p.s.: This is 15+ year old behavior.

I quite agree. I see the behavior in 4NTv8. The OP in the thread I cited (me too) only unset path as a test.

It searches the path, and then apppath. I have a version of write.exe, that loads the jpsoft 'tc.exe' through an apppath 'tcu.exe'. However, if i create a tcu.exe in the path, then it will run that tcu.exe first, without getting to apppath.

So even if you have apppath set to something like excel.exe, it will find a command in the path first that uses this name.
