Can't find a strings on x64dbg, IDA PRO

Question

I'm newbie in this and wondered that if i could crack this Snapgene program.

1. I searched error strings about registration code on x64dbg and IDA PRO, but they can't find them. enter image description here enter image description here

2. I checked Snapgene.exe on Detect it Easy and it says, that program is not packed. enter image description here

3. How do i find the strings?

4. Why i can't find these error strings on debug program, if Snapgene program itself is not packed??
