Hi,

I got this error message if I try to build the app:

Error: Exit code: EACCES. spawn filename.exe EACCES
    at ....\node_modules\builder-util\src\util.ts:129:16
    at exithandler (child_process.js:315:5)
    at ChildProcess.errorhandler (child_process.js:327:5)
    at ChildProcess.emit (events.js:315:20)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:275:12)
    at onErrorNT (internal/child_process.js:465:16)

I use NSIS and this error occurs if I have this line in the NSIS file:

!macro customHeader
   RequestExecutionLevel admin
!macroend

My package.json contains these related values:

win: {
          icon: "public/icons/icon.ico",
          target: "nsis",
          requestedExecutionLevel: "requireAdministrator"
          ......

I tried this under Parallel Windows 10, Oracle VM Windows 10, and native Windows 10, and this issue exists under each of them.

Thanks for any assistance.

It solved.

If Windows console is running in Administrator mode then no errors and it works fine.

Hi! I've hit this too. Writing my notes here because this was the best hit in the issues, and I'll probably hit this again later.

This appears to be because electron-builder will run the just-generated installer in order to get the uninstaller, so that it can be signed. This behaviour was originally introduced in #526, following instructions from the NSIS wiki.

The better workaround is to set __COMPAT_LAYER=RunAsInvoker in the environment before running NSIS; this forces everything to run unelevated, which means that the installer can generate the uninstaller to be signed.
