New Inno Setup Installer Script Samples (Version Compare, Running Processes)

A long time ago, I used Inno Setup extensively on open source projects, such as Code Beautifier Collection (http://code.google.com/p/lextudio). At that time I was able to share a few tips,

Recently during the development of Touch Mouse Mate (http://touchmousemate.codeplex.com), I wrote two new installer scripts which may be interesting for Inno Setup beginners.



32 Bit/64 Bit Installers

There are two approaches if your product is going to be installed on both 32 bit and 64 bit Windows. You can write a single installer to support both, or write two installers (one for 32 bit and the other for 64 bit).

I don’t like to put all stuffs in one installer as that can make the installer too big (for example, you need to pack both Visual C++ runtime x86 and x64). Therefore, I choose the two installers approach for Touch Mouse Mate.

The following rules are set (avoid possible confusion),

  • 32 bit installer refuses to run on 64 bit Windows. 64 bit installer refuses to run on 32 bit Windows.
  • Dependencies (such as Visual C++ runtime and .NET Framework) are packed.
  • Platform dependent library files are put in different folders (x64 or x86).

Version Comparison

The version comparison code has been updated slightly in the two installer scripts.

psvince.dll 64 Bit

I am not a Visual C++ expert, and I don’t want to waste my time compiling 64 bit psvince.dll from source code. Therefore, I wrote a processviewer.exe command line utility in Delphi (Turbo Delphi 2006) to provide the same functionality.

However, as this becomes an executable, we have to pack the command line utility and release it to temp folder on demand, which has been demonstrated too in both installer scripts.

Hope you like them.
