Inno Setup Check If Already Installed

Setup
Hello,
I am trying to install ASPI driver to a certain PC. Since different PC hardware and OS requires different installation techniques, I wish to use inno setup to check the OS and install the correct command.
Adaptec ASPI driver (downloaded from Download.com) comes with a file named install.bat. The install.bat requires a command line options as below:
=
1. Run INSTALL.BAT with the target operating system
command line option specified:
X86 ( for Windows 98/ME/NT/2000 )
XP32 ( for Windows XP 32-bit )
XP64 ( for Windows XP 64-bit )
e.g. 'INSTALL.BAT X86'
I have searched thru' inno help file but could NOT make out much on how to check the windows version. What I want to do here is to check the windows version with inno setup and issue the correct command line with the install.bat.
For example, if inno setup check that it is 32-bit XP, then it will run 'Install.bat x32'.
- Can you please show me how to check the windows version with inno setup
- and run the install.bat.
Thanking you in advance for all.
Best regards,
Kate.
