FRESH installation of SGPro (4.2.0.895 (64-bit)) does not even start

Hi,
so I recently purchased SGPro and installed it. On two different machines (both Win 10 Pro), it doesn’t even start (first start).

OS: Win 10 Pro
SGP: 4.2.0.895 (64-bit)

from first start;

and the following;

Update: I’ve installed an old(er) version (4.1.0.886 (64-bit)) that starts as it should. Afterwards I upgraded from within SGPro to the latest 4.2.0.895 w/o any issues.

Ok, thanks for the report, I will try to reproduce this.

Sure, hope it helps. I upgraded to 4.2.0.900 few minutes ago - never had the same issue. I think we can close that topic, unless you’re able to reproduce that issue and want to inform your forum users here.

CS,
