NSIS installer always show "XYZ cannot be closed. Please close it ..." when there is other process name contains "XYZ"

• Electron-Builder Version: 23.0.3

• Node Version: 16.3.1

• Electron Version: 16.2.5
• Electron Type (current, beta, nightly):current

• Target: Windows 11

In my case, productName of my project is XYZ, it allows user to install a service named XYZ Helper on Windows, which runs when the operating system starts up. When I use electron-builder(23.0.3) to package(target: NSIS), the installer always show XYZ cannot be closed. Please close it manually and click retry to continue. even after I'm sure to quit XYZ completely. Only after I also stop the service named XYZ Helper, this step can be processed. But XYZ Helper is not part of XYZ, which is a separated process and should not be stopped. electron-builder(22.14.13) doesn't have this problem.

Getting the same error when trying to change the install location to Program Files. When using the default install location, or install to any directory outside of Program Files, am not getting this error (eg. C:\MyApp)

Originally using 23.0.3, but tried upgrading to 23.3.1 & 23.3.2 (pre-release), but both also had this issue.

Interestingly if right clicking on the .exe installer and selecting Run as administrator this issue does not come up. So not sure if this is a signing issue? I do not currently have any signing implemented for windows, but will try this.

Also tried downgrading to 22.14.13, but got a different error: Error opening file for writing: C:\Program Files\MyApp\Uninstall MyApp.exe

Using the custom path described in docs: https://www.electron.build/configuration/nsis.html#common-questions

EDIT: main goal to install to Program Files was resolved by simply setting perMachine to true rather than setting manually with custom .nsh script. This issue had the same error message, but ultimately a different issue.

Saw this in our project too - still a problem in v23.3.3.

From a bit of looking around and experimenting it seems that the addition of args.push("-INPUTCHARSET", "UTF8") to packages/app-builder-lib/src/targets/nsis/NsisTarget.ts is causing the issue (but no idea why).

With that line removed the produced installer works fine.
