After upgrading to 24.13.2, Windows NSIS installer Failed to uninstall old application files when there is an app running

[zaichaopan-alianza]

• Electron-Builder Version: 24.13.2

• Node Version: 18.14.0

• Electron Version: 29.1.1
• Electron Type (current, beta, nightly): current

• Target: Windows

After upgrading to 24.13.2, when installing nsis installer when app is running, it shows below error "xxxx cannot be closed. Please close it manually and click Retry to continue"

Click Retry will keep showing the dialog again. When click Cancel, it shows "old application files cannot be uninstalled"

Versions before 24.13.2 do not have this issue

When try previous version 24.13.1, It shows dialog xxx is running, click OK to close. After click OK, running app will close and install will continue.

Step to reproduce

• upgrade electron-builder to 24.13.2 and create a NSIS installer
• install the installer and have the app running
• click the installer again to install or make another new installer to install

Seems like the fix in #8059 introduce this issue. Have anyone run into the same issue?

Thx a million !

What's your nsis electron-builder config? I'll try and repro this locally

Thanks for the repo! Really appreciate it.

Will take a look this week when I find some solid time outside of work

SYSTEMROOT = "c:\windows", The path c:\windows contains special characters, so it needs to be enclosed in double quotes to work properly.

!define SYSTEMROOT "$%SYSTEMROOT%"
nsExec::Exec '"${SYSTEMROOT}\System32\cmd.exe" /c tasklist /FI "USERNAME eq %USERNAME%" /FI "IMAGENAME eq ${_FILE}" /FO csv | "${SYSTEMROOT}\System32\find.exe" "${_FILE}"'

[zaichaopan-alianza]

@beyondkmp I tried the fix #8133. The issue is no longer reproduced. Thanks a lot!

Releasing in 25.0.0-alpha.4

[sumeet-singh04]

Would this fix be backported to 24.13.3 ?

[mmaietta]

Unfortunately, AFAIK it's not possible to backport fixes to previous versions due to the @changesets CI/CD approach. It's only able to roll forward AFAICT. Happy to be disproved otherwise though!
