Some back story: Several years (10?) ago I wrote an app that was on a Windows 7 box. It’s been working fine, and the client likes the app. The problem is that the Windows 7 box died (I don’t know the cause of death), and they want to install it on a new Window 11 box.
Apparently, one needs some sort of certificate and/or installer now. I have no clue. Can someone point me in the right direction?
All of my dozen or so apps are primarily for Windows and are currently running on Windows 10. I’ve never done any notarization of any kind - the worst that happens is the user gets a “Do you allow this program to make changes on your computer?” dialog when the installer (created with InnoSetup) runs Ithe dialog may not even show depending on how they have the User Access Control or som such set. I don’t think InnoSetup does anything special either, it primarily just automates the process of keeping the executable with its libs and resources, while also handling stuff like desktop shortcuts, Start Menu items, icons, and so forth.
Windows often throws a warning/error when attempting to run something “unknown.” The trick is to find the ‘more info’ link in the warning, which when clicked will expose the ‘run anyway’ button. Also note that it behaves a bit differently if the computer is not connected to the internet.
just install or unzip+link it for him via TeamViewer or RustDesk.
without app sign (verified producer) a anti virus could possibly nag, but this yould add as exceptional case.
AFAIK, the only use of the GUID is in the “Add/Remove Programs” control panel.
Suppose “My App version 1.2.3” is already installed and the user installs “My App version 1.2.4”. If they use the same GUID then the control panel will treat the new install as a replacement for the old one. If they use different GUIDs then they are treated as separate apps.
If your users should be able to install multiple versions of your app then each version should use its own GUID. If there should only ever be one version installed at a time then use the same GUID.
