Is it possible to control which files to install from command line for INNO installer?

Question

I would like to control a subset of files and only allow some of them to be installed if run with a command line switch for instance.

Is this possible?

For example

if (some condition)
    install full set of files
else
    Install other set of files

Alternatively I can just run another installer but then I have to pass the file/path location to that second installer. There is also the issue of bundling that second installer with the first one. I think that part is not that difficult though

Answer 1

Yes, it is even rather easy. There are several ways to do this, all of which depend on Pascal scripting.

Method 1

• You can use the GetCmdTail, ParamCount, and ParamStr functions to obtain the entire or parts of the command-line.

• Then you can use the Check parameter on separate files. Hence, each file will be installed if and only if the called function returns true.
