Help with install types
I'm having a bit of trouble getting install types working the way I'd like them to.

I am creating an installer containing map files for two separate products, I'll call them A and B. The installer checks for the existence of the products and changes the components page accordingly. This works great as is. So if the installer detects A and B, they're both on the components page. If only one is found, just that product is listed.

The problem is introduced when I try to create install types. I have defined two install types (Day and Night) to allow the user to install the appropriate version of the maps. However, if product A is not installed, installer will continue to install the files associated with that product.

Hopefully the script will help illustrate my problem. I would like for my installer to do the following:

1) Check for required software and populate the components correctly (this works)

2) Have install types that don't install unnecessary components! (this fails miserably!)

Thanks for the help!
Todd

Ahh, the script might be helpful.

I think a simple approach to this is to use an installoptions page that has the components on it, and then check the value in the section. I have made some modifications to the script to show this. I have made the sections into one, and checked the value and decided which .map file to install.

I realise this is not an answer to you question, it's just a suggestion on other ways to get rid of the problem.

Thanks, Jason!

I was actually thinking of doing what you've suggested and using an InstallOptions page.

After incorporating the installoptions and tweaking my validation function, I was able to get it working.

Now I just need to set the page header and top text, if it's possible.

Thanks again,
Todd

Put before the InstallOptions page is displayed:

!insertmacro MUI_HEADER_TEXT "InstallOptions Title Text" "InstallOptions Subtitle Text"
InstallOptions::dialog "mapfiles01.ini"
