I know, but when I open the upgraded Logo comfort version you can see it is V8.1

The other downloads were demo versions.

I always edit errors to keep it readable (Flemish-English mix ) and to make small adjustments to avoid reapplication of my own response.
... but I'll keep that in mind!

To get back to the problem with the Logo! Version, to download the latest version, open the following link:

Demo software , upgrades/updates, Drivers

Choose from one of these files.

Upgrades

Upgrade your version of LOGO! Soft Comfort: V1.0 / V2.0 / V3.x / V4.0 / V5.0 / V6.x / V7.x to V8.x

When downloading, the new version V8.1 will be installed separately.
The V8.0 version is also available.
