I have an Installshield 2008 project setup to create a MSI setup.
What I now need to do is create a "hotfix" for my application i.e. replace the current dlls with newer ones. This must be uninstallable so the users can roll back changes. - Using the "patch design" seems to be the best option.
However I also need to deliver a new folder with some files in. Is this achievable with the "patch design"?
If not how can i achieve this? Minor upgrade?? - But does that satisfy my requirement of being able to uninstall just the hotfix?
You can create an uninstallable patch with the Patch Design view. However, one thing to note is you cannot add new records to the CreateFolder table, as this will prevent the patch from being uninstallable (see http://msdn2.microsoft.com/en-us/library/aa372102.aspx). If you needed to add a folder and still allow the patch to be uninstallable, the folder would need to be created through a custom action.
