[Run]

or

[Run]
Filename: {sys}\sc.exe; Parameters: "create nginx start=auto binPath=\"{app\nginx.exe}\" " ; Flags: runhidden

Answer 1

Compiler tells you what to do. Use two consecutive { chars:

Filename: {sys}\sc.exe; Parameters: "create nginx start=auto binPath={{app\nginx.exe}"; Flags: runhidden

The problem is that compiler treats everything enclosed by {} chars as constants in scripting sections. So when you wrote:

Parameters: "create nginx start=auto binPath={app\nginx.exe}"

the compiler took that {app\\nginx.exe} as a constant (just like eg {app} is). And since there is no such constant, you got this error.
