Update: Since the problem couldn't be solved at first, I was referred to the product development in Moscow. They were able to help me reinstall Kaspersky Plus. The problem was the setting “Intel Turbo Boost” (Intel Turbo Boost Max Technology 3.0 / Intel Turbo Boost V3) in the BIOS. After I disabled it, I was able to install Kaspersky Plus without any problems. I don't know whether the original problem (the product doesn't start due to an error message “Microsoft .net failed to initialize”) has now been solved or not. However, I will ONLY get in touch again IF the problem occurs again.

¿Pero qué versión de KSOS para File Servers? ¿Qué numeración?

La version del KSOS es para file Servers y el sistema operativo es Windows server 2022

Here's where Kaspersky doesn't seem to get the problem. It's that we all totally disagree with this whole transition in the first place, like, just go back to where it was beforehand. Too many features and locations now gone, and now we're dealing with a shady company virtually no one uses their service (PureVPN), who's had a bad reputation and is easily discovered that they do NOT deliver on quality and in respects to privacy and security, they're pretty questionable. Clearly a blatant measure to cut costs, at the cost of butchering the whole VPN experience for all. I can ramble on this for another whole two paragraphs.

Clearly they so desperately needed to cut costs, at the cost of butchering the whole VPN experience. Main reason why I loved the VPN, was the Catapult Hydra protocol, which is the fastest I've seen so far. I literally did the same thing, read their new "VPN Statement", and then investigated wth is PureVPN and found it super sketchy. I'd suspect they went for the absolute cheapest option available in the market. I feel like the VPN is practically killed off in a sense. It's dead to me though.

С пингом есть проблема! YouTube через VPN с российской лицензией пока не заработал. Тех поддержка решает этот вопрос, им известна ситуация, так меня проинформировали. Есть проблема с доступом к сайтам с нейросетями, приложения и сервисы через VPN не работают, тп тоже было сообщено. При включённом VPN было замечено, что регион не меняется, к примеру если выбрать США то сайты, сервисы знают ваш реальный регион. Все это немного странно.

Cutting costs is gonna be why. Just check out the PureVPN website, I found it to be mediocre and their Holiday Sale alone, kind of tells me that they were the cheapest alternative Kaspersky could've chosen to switch to. And I'm extremely disappointed and salty about it. I want that Catapult Hydra and that manual WireGuard config. Also their Turkey/Türkiye server has become abysmal.
