Hello, I am wanting to allow my users to install multiple instances of my application, just like Microsoft allows with SQL Server. Can someone please point me in the right direction to accomplish the following install and uninstall sequences.
Install Sequence ---------------- 1. Prompt user to "use default instance" or supply an instance name (if default instance is already installed, "use default instance" should be grayed out) 2. Verify that instance name is not already used; if it is, do not allow the user to continue. Also validate that the instance name does not contain any spaces or non alpha-numeric characters. 3. Modify HKLM\Software\MyCompany\MyApp\InstalledInstances to append my instance name (if it already exists, add my name to it) 4. Use the user-supplied instance name in all of my RegistryKeys so that the RegistryValues get installed as HKLM\Software\MyCompany\MyApp\InstanceName\XXX. 5. Somehow use the user-supplied instance name within the saved MSI state so that subsequently installed instances may have entirely different feature sets and MSI is able to differentiate between them (i.e. perhaps using two entries in AppWiz.cpl or if possible using a single entry but allowing user selection during modify/repair/uninstall) Uninstall/Repair Sequence ------------------ 1. If using two separate entries in AppWiz.cpl, detecting which instance I represent. If using a single entry, prompt user to select an installed instance to uinstall/repair. 2. Use this instance name to perform the uninstall/repair. I'm sure that I can figure out Install.1,2 but I'm completely lost with the rest. Any help is much appreciated!
