Choose the package that best fits your environment: installer or portable ZIP, available for both 32-bit and 64-bit Windows systems.

Which variant should I choose?

Setup (Standard): Recommended for most users. Installation creates shortcuts and makes future updates easier.
ZIP (Portable): Useful for USB sticks, test environments, or systems without installation rights. No classic installation required.
64-bit: Recommended for modern Windows systems.
32-bit: Only for older 32-bit Windows installations.
Beta: For users who want to test new features early. Not recommended for production or highly stability-sensitive environments.

If you are unsure, choose Setup 64-bit.
