Simpack - Installation

Hello,

I am about to install Simpack for the first time. In the software download platform, I see two types of versions, e.g. Simpack  2026 and Simpack 2026x each with a Golden version and some Refresh levels.

The questions are,

  1. What is the difference between Simpack 2026 and Simpack 2026x? For example, the 2026 has Golden + upto Refresh4 and 2026x has Golden + Refresh1
  2. If we choose for one of the above, can we directly install the latest "Refresh" or we need to install Golden first and then the desired Refresh level?

Thanks in advance.
