PathWeaver couldn't be launched

recently, we have wanted to use PathWeaver, so i search lots of info. on the Net
and i follow like this:
first : open our vscode
second: click “W” and search “start tool”
third : find PathWeaver then click it

but it didn’t work!!! what’s going on???
(btw we can use shuffleboard )

Works for me, Windows 11.

Debugging steps to try

  • Reinstall WPILib via the Installer.
  • Share screenshots of you pressing the Pathweaver button
  • Does opening Pathweaver via the desktop shortcut work?
  • What OS?

Please try/share information on all of the above.

What WPILIB version are you using? (W → WPILib: Open Project Information).

Can you find any hs_err_pid*. log files anywhere with timestamps that match your crash?

sry i can’t send my attachment
so i use google drive to show ( in word file)

That shows 2022.4.1, which is the latest. It still might be worth reinstalling as Daltz3 suggested. Also still worth looking for crash files.

we have reinstalled three times.
so should we change our computer? thanks

Above you say: “it didn’t work!!!” can you be a lot more specific about what it did. Did it do absolutely nothing? Did it give you a error message?

Did you manage to find any crash files?

If you’re on a mac (this happened to me with the glass tool), go to the wpilib folder in your user folder then go 2022 > tools > artifacts > pathweaver-something.jar

(as a side note, I recommend path planner)
