unable to start windows service after registering for start node server using inno setup script

Hello Stack Overflow community,

I'm facing an issue with an Inno Setup script and need some assistance. During the installation of an executable (Exe), I have to register one windows service for start my node server to run my angular ssr build. but after creating windows service it shows pause status, when i manually start/pause the windows service then I am getting error.

actual command for start node server for run my angular ssr.

"C:\Program Files\nodejs\node" "C:\Program Files (x86)\envVarIssue\ecom\angular\server\main.js"

when I run above command in cmd then it run perfectly.

but I have to start server using windows services. so for that I install windows service, node.msi during installing my exe app.

when I installing exe, windows service create, but it doesn't starting. it show pause status.

see below attachment of error

for register windows service I used, nssm.

Can anyone help me understand why this issue is occurring and how I can resolve it? Thank you for your assistance.

I provided my code please check it.

[Code]

The problem was the combination of Inno Setup and nssm, which both are escaping double quotes with double quotes. That makes multiple double quotes necessary.

Solution:

Filename: "{app}\{#NSSM64}"; Parameters: "install {#MyAppShortName} ""{pf64}\nodejs\node.exe"" """"""{app}\ecom\angular\server\main.js"""""""; Flags: runascurrentuser runhidden;

For Log error and std res you can set addition options of nssm

Filename: "{cmd}"; WorkingDir: "{app}"; Parameters: "/c nssm set {#MyAppShortName} AppStdout ""{app}\myServiceLog-stdOut-log.txt"""; Flags: runascurrentuser runhidden;
