after setting up an external tool using the menu item:

Tools -> Configure Tools...

in IAR Embedded Workbench.

Possible solution

• Specify a shell (for example cmd.exe) as Command
  and specify script(s) (for example .bat file(s)) to be called as Argument.
• Avoid specifying an Argument variable (such as $PROJ_PATH$) as Initial Directory.

Failing Example

Specifying Command

C:\TEMP\doit.bat $PROJ_DIR$

leads to the error message

The handle is invalid.

OK Example

C:\Windows\System32\cmd.exe

and Argument

/C C:\TEMP\doit.bat $PROJ_DIR$

is OK.
