21.1.01 actually 20.0.01 when downloaded?

Before downloading the install driver for the newest edition, I was running 20.0.05. The downloaded version opens as 20.0.01, giving me the warning that my files were created using a newer version and saving them might corrupt the data.

So I tried re-downloading 20.0.05, but it’s still only opening 20.0.01. Any ideas how to fix this, or how to at least get back to 20.0.05?

under “older versions” you can download all old versions and install them, without first uninstalling your current version. It is always recommended to make a bundle backup so you don’t lose any data or settings.
Regarding the warning with older files in new LB version (2.1.01), I often change versions to test them and have never experienced problems with incompatibility of project files. However, I only have CO2 and diode laser files, no fiber and UV.
