The browser loads the DLL file before waking up Electron - dll

Question

my electron app depends on C++ dll files. I was able to wake Electron App up in the browser, but the file it depends on is not loaded, I got win32 error 126. If I choose to open Electron directly by double-clicking instead of opening it from the browser, the files it depends on will load in.Everything is all right.
What's the difference between using a browser to wake up an Electron app and double-clicking to open an Electron app ?
electron-builder Version: 20.19.2
Electron Version: 2.0.18
my code:
package.json
"build": {
"extraResources": [
{
"from": "./a.dll",
"to": "../"
},
{
"from": "./c.pem",
"to": "../"
},
{
"from": "./b.dll",
"to": "../"
}
],
"nsis": {
"oneClick": false,
"allowToChangeInstallationDirectory": true,
"createDesktopShortcut": true,
"createStartMenuShortcut": true,
"include": "script/urlProtocol.nsh"
}
}
urlProtocol.nsh
!macro customInstall
DetailPrint "Register voice URI Handler"
DeleteRegKey HKCR "voice"
WriteRegStr HKCR "voice" "" "URL:voice"
WriteRegStr HKCR "voice" "URL Protocol" ""
WriteRegStr HKCR "voice\shell" "" ""
WriteRegStr HKCR "voice\shell\Open" "" ""
WriteRegStr HKCR "voice\shell\Open\command" "" "$INSTDIR\${APP_EXECUTABLE_FILENAME} %1"
!macroend
a.dll、b.dll、c.pem are in the root directory of the project

Answer 1

Error 126 is ERROR_MOD_NOT_FOUND.
You probably rely on relative paths somewhere. You don't control the current directory when your application is started so no modules should be loaded from paths starting with ./ nor ../.
You should also quote your registered verb command correctly:
WriteRegStr HKCR "voice\shell\Open\command" "" '"$INSTDIR\${APP_EXECUTABLE_FILENAME}“ “%1"'
