I need my installer to behave differently based on the version that it is upgrading.
The installer will encounter one of three scenarios. A first time install, upgrade against the current major version, or upgrade against previous major version.
The previous installer I wrote wasn't difficult because it was the first for the current major version, so only two possiblitiles, either a new install or an upgrade. I have a custom dialog that only shows on ugprade, but now that the upgrade can be from the current major version, the verbiage is not accurate. I need to follow different paths based on the version being upgraded. How do I do this?
I can lay out the three different scenarios if necessary, but I think the above shows what I'm looking for.
Thanks.
