Problem Description

Didnt compile with latest version 2.5.0-beta3. Previously I used Version 2.4.2 every thing works fine.
Error shown:
exec: "cmd.exe": executable file not found in% PATH%
Compile Error for the Board Generic ESP8266 Modules.

It does not seem the same problem, but check this please:

You installed with Board Manager or from Git?

Ok, forget my last comment.

The most common problem is that the user you use in Windows does not have enough privileges to execute "cmd.exe". Run Arduino IDE as Administrator and it should work, or elevate your user privileges.

Another reason may be that really the path to cmd.exe is not in your %PATH% environment variable, check your "System" environment variable and add %SystemRoot%\system32.

Another reason is that the cmd.exe file does not really exist (search it in %SystemRoot%\system32), in which case your Windows is corrupt for some reason. You can try copying cmd.exe from another computer with the same Windows version or reinstall Windows.

This is either a problem in your Windows, or a problem with your installation. I suggest a clean install from scratch of the Arduino IDE and then of this core. If that doesn't work, you'll need help from someone who knows a bit about how Windows works to figure out why cmd.exe isn't found. I suggest seeking help at esp8266.com or stackoverflow.

Either way, it's not a problem in the core hosted in this repo. Closing.

I got the same error. Core 2.5.0, Windows Seven
The solution, for me, was to delete all folders in Temp (C:\Users<YourUsername>\AppData\Local\Temp) because enabling verbose output during compilation I noticed that the compiler used a folder with compiled binaries of another sketch.

It's not a PATH problem, I have not C:\Windows\system32 in my path and it works.

Further investigations.

In 2.4.2 core platform.txt has this line

## windows-compatible version without git

in 2.5.0 core platform.txt there are these lines

## windows-compatible version without git
recipe.hooks.core.prebuild.1.pattern.windows=cmd.exe /c rem cannot sign on windows

in 2.5.6-Dev core platform.txt these lines where removed again

So I was wrong, I need C:\Windows\system32 only for 2.5.0 but it is not a Windows problem. It was changed something between cores <=2.4.2 and 2.5.0 that need cmd.exe.
If I put a comment on recipe.hooks.core...... I get an error that python is not in my PATH.
