running InstallUtil {app}/file.exe in inno setup

Question

I want to copy service files to {app} directory and then use this as a parameter in InstallUtil.exe.

Here\'s some part of my code :

[Files]
Source: W         


        

Answer 1

{app} may contain spaces, and so must be properly quoted when using it on command lines:

[Run]
Filename: {dotnet40}\InstallUtil.exe; Parameters: """{app}\WCFService.exe"""

The outermost set of quotes is for Inno itself; each pair of doubled quotes within that will end up putting a single quote on the command line.
