(I am using Advanced installer, but should be similar when using Wix or InstallShiedl)
What is the recommended way to test if a valid license is present during app install ? this test must be before anything is really installed
For sure several have faced that. Any example ?
What i particularly want to avoid is that the user install a newer version over/instead an old one, but then it does not validate because maintenance plan is expired (but his old version was working = prepare for the claim...)
