Install metabase using nssm and Inno Setup script

Question

I want to open an administrative CMD window using Inno Setup and want to install:

nssm install metabase

I tried the following function, but it doesn't work.

Exec(ExpandConstant('{cmd}'), ' nssm install', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);

Please someone help me. Thank you in advance.

Answer 1

You are effectively executing:

cmd nssm install

That wouldn't work anywhere, not only in Inno Setup. It should be:

cmd /c nssm install

Though, it's an overkill to run nssm via cmd. Run it directly:

nssm install

In Inno Setup Pascal Script:

Exec('nssm', 'install', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);
