Remove an InstallShield feature
We have a huge installer written in InstallShield, and part of the code is an optional feature. I am working on an installer in NSIS to take the place of installing that feature. Right now that feature is implemented as a set of merge modules.
What I want to do here is have the future InstallShield code launch my new NSIS installer in place of the current feature.
During an upgrade, I will need to detect and remove the old 'feature' of the previous InstallShield installation, then launch my NSIS installer.
Any ideas here?
