Is it possible to send parameters to InstallShield prerequisites?

I am evaluating InstallShield 2010, 开发者_如何学Cand am trying to set some command line parameters to the SQL Server 2008 prerequisite at user runtime. It appears that the prerequisite is defined entirely in the .prq files (xml-style).

Wise for Windows used WiseScript to call the prerequisite installations. InstallAware seems to have something similar, with their own scripting. Does something similar exist for InstallShield?

We use IS v12; I built a .prq file for the purpose (they don't supply a .prq for SQL 2008 for IS v12). First I went to http://msdn.microsoft.com/en-us/library/ms144259.aspx to get all possible cmd line args. Then I used the IS PRQ editor to create the basic .prq structure. Then I hand-edited the .prq (xml) file for (a) easy minor adjustments in the future and (b) to simplify version control diffs.

Yes - by right clicking on the SQL Server prerequisite -> "Application to Run"' tab -> "Specify the command line for the application".

The only way I know how to do this is to write a Helper.EXE that the PRQ calls. The EXE would need to detect the windows settings and silently pass the correct arguments to the real Prereq EXE/MSI.
