To clarify, for current users who are already using KS 6.x on their machines, activation is still allowed (I just activated my 6.1.5 version just to test this). However, for new machines or new registered accounts, KS 6.x activation will not work. This is to ensure that future users do not continue to use a version that is no longer supported and meeting its sunset soon. All new users and new machines are better off using KS7 or KSE.
I still believe the language of “The KS 6.x version is still available to download and activate until April 30, 2020 (6 months from now) for current users” is misleading. It makes no mention of new machines vs. known machines at all.
Same problem for me. I was trying with KS7, tried to go back to 6.3.3, and it will not let me. I believe it was tied to the forced business email in KS7 to try features. Original 6.3.3 was my regular email address, since I am a contractor and use Katalon with various clients. I was going to purchase for my personal machine, but is no longer supported by Katalon since I use regular gmail address.
Not with that version.
It will only be possible If you pay for Katalon Runtime Engine license, which is required for running Katalon via CLI. Consult what kind of KSE license fits your CI arch in Katalon.com/pricing.
