Subject: Re: [airspy] Installer
Inno is what I use and it does create an application specific tracking GUID for the program to make updates more simple and reliable and which enters it into the Windows "Apps and Features" so it can be tastefully managed by the OS. Otherwise, it's simply un-compresses itself into the installation folder. It's very convenient for users to have a 5 click solution to a new version with no jacking up of their configuration files.
Creating an updated installer is opening the script, setting a date or version, and clicking one button, so hardly a chore.
