“ So my unlock code eventually expired and was looking into fixing that problem permanently by disassembling the exe (Visual Basic app) and debugging in assembly. Trying to understand what's going in in VB from assembly is quite painful. Would have been easier if the software would have been coded in C or C++. Anyway that avenu led nowhere.
I ended up realizing you can just change the clock of you PC and use a temp unlock code

You can use this code to unlock Wintes2: C98KCJW6 expires on 1/1/2020 (just set the clock of you PC before this date before starting the app)”
