automated build inno setup error

This 开发者_StackOverflowquestion is regarding getting version directly from assembly. I have followed instructions from this post

My script looks as follow.

#define MyAppName "Keyboard Trader"
#define SrcApp "Keyboard Trader.exe"
#define FileVerStr GetFileVersion(SrcApp)
#define StripBuild(str VerStr) Copy(VerStr, 1, RPos(".", VerStr)-1)
#define AppVerStr StripBuild(FileVerStr)

But while compiling script it throws following Error

Compile Error!
Line: 12
**Error: [ISPP] Actual parameter VerStr is not of the declared type.**

What I am missing here?

GetFileVersion() is returning a blank string as it can't find the the SrcApp path. Try specifying a fully qualified path or using:

#define SrcApp AddBackslash(SourcePath) + "Keyboard Trader.exe"
