During feature-based prerequisite installation it requires to exit the other setup process, which is the main app installation. There is no way to exit it.
Steps:
1. Create a project that requires .net prerequisite, in my case web-based .net 4.6.1 installer. Add it as feature-based prerequisite.
2. Build the project as MSI.
3. Run the MSI on Windows 7 or other OS without .net 4.6.1 support.
4. The .net web-based installer needs the other installer to finish the installation.
5. Click "Cancel" button on the AdvInst installer window to finish the installation.
Result:
The main installation process does not exit, nothing happens.
Expected:
Main installation terminates on "Cancel" click, so .net setup can continue.
Please let me know if you need MSI, logs or else, then I'll Email the data.
Thanks!
