Since Vertus went out of business (the company is effectively defunct as of 2020), getting v3.2.4 to run on modern systems requires workarounds.
Problem 1: "This app cannot run on your PC" (Windows 11)
Problem 2: Photoshop Plugin not showing (Photoshop 2022+)
Problem 3: Crashing on High-Resolution images (4K+) Vertus Fluid Mask 3 v3.2.4
Problem 4: No Masks in macOS Catalina or later
