Conditonal Install Directory
Hi all! Long time reader, first time poster.

Is there a way to conditionally set the value of $INSTDIR? Let's say that I'm installing into a tomcat directory that I've renamed "C:\tomcat4", however, the person using my installer might have tomcat installed in the default directory "$PROGRAMFILES\Apache Tomcat 4.0". I know that IfFileExists only works inside of sections and functions, so is there any other way to achieve what I'm trying to do?

Thanks!

If the location is saved somewhere, you can set $INSTDIR using StrCpy in .onInit.

If you have used a registry key, use InstallDirRegKey.
