My question is as follows (I hope that someone will be able to help :) ):
I have an Installshield InstallScript Project with prerequisites.
Once the user tries to run the setup file, it shows the prerequisites dialog and the user is able to install the prerequisites - so far so good.
After the application is installed, the user decides to remove the prerequisite (.Net 4.5 in our case). He later wants to remove the application as well and launches the setup.exe again (he is not using the Add Remove Programs of Windows). When launching the setup file, the first dialog that appears is the prerequisites dialog.
Our setup supports only uninstallation if the application is already installed so there is no need for the prerequisites installation.
BTW, when uninstalling from the Add Remove Programs, the prerequisites dialog is not shown.
So, the question is: how can I disable the prerequisites dialog when launching the setup.exe on the second time?
