Заведите родителям отдельную учётку my.kaspersky. Защитой вроде можно поделиться. Хотя инструкции для KTS не нашёл, но поделился. Надеюсь лицензионое соглашение не нарушил

@Yoji You are welcome and thank you for your feedback. I hope you will be able to fix this issue, if not Kaspersky Tech Support is your best option.

Всё нормально, друзья!!! После того, как в течение двух месяцев служба поддержки Касперского переливала из пустого в порожнее (как в старом анекдоте советских времен, когда мужик приходил в магазин купить туалетную бумагу, которой не было, а ему другой покупатель говорит - я им уже и унитаз приносил, и задницу показывал, а туалетной бумаги, как не было, так и нет), давая шаблонные неработающие рекомендации, я сделал все проще. Удалил вручную все папки и файлы с упоминанем Kaspersky из Program Files x86, Program Data, AppData, а также все ветки и ссылки реестра опять же с упоминанием Kaspersky. И заново его установил. И все работает, как часы - и сам компьютер, и Касперский Премиум. И в списке установленных программ он появился, и следов удаленного Касперского больше не появляется... И не потребовалось никаких танцев с бубнами с переустановкой винды и восстановлением системы. Вот как-то так...

вы про развитие Kaspersky OS ?

Вопрос в следующем: в подписке, можно подключить три устройства, одно моё, другие для родителей, родители тыкают во всё подряд и плохо разбираются в компах, можно ли ограничить второстепенных пользователей в правах на изменение в настройках и лицензиях, чтобы они не могли на ровне со мной добавлять устройства, управлять лицензией и т.д. Надо что бы мой первый аккаунт был "Admin", а другие "User" (а лучше "Lamer").

Unfortunately it is not possible. Locally only.

No success so far unfortunately although your help is very appreciated and I did all things exactly as suggested, seem logical of course and would have been the things done by myself (or very near to it), I just wanted to avoid a complete uninstall, new download etc. but did it Uninstalled successfully, I did not see a single Kaspersky file after this (the uninstall routine suggested to keep the subscription data but I removed them too because maybe exactly this caused problems, could not be wrong in my opinion) I did NOT try to open the UI immediately after the new installation (finished successfully without any errors or so) but did a shutdown and restart instead, cannot be wrong in my opinion either because the software should know/check if it exists on the pc and ask for the license or something similar even after 2, 5 or 20 restarts or not.. After shutdown/restart I had to try to open the software/UI of course, you said "The new application has to synchronize/connect with (your) MyKaspersky account to *pick-up* the License key".. - "You must sign into the Kaspersky application - using the same email address that was used to buy the Kaspersky Standard subscription. Don't try an add an Activation code & OR a License key - anywhere!!" BUT I only got this window asking for an activation code again unfortunately which is a real mystery to me because I did not make a single mistake in installing etc. so I am on a dead end again and do not have any ideas anymore to solve this, seems to me that the software thinks that I do not have a valid license or so maybe but I never did anything other as buying the software legally and install it, all other things would be very silly with an av program anyway (and all is shown as valid in my account with expiration data, license number etc.) So how to continue, would the support give me an activation code in this situation, maybe ? Not sure if this would work anyway or if things are messed up already in hidden areas of the registry or so (not by me but by Kaspersky suspecting wrong things maybe etc.) I will definitely not make a complete os reinstall with creating images and all things necessary, I did never expect that installing/activating Kaspersky would be so difficult, I really would like to use it but am not far from giving up and I think the only solution (if any) would be trying an activation code By the way I used Emsisoft Ant-Malware last years without any problems but the license expired and only Windows 10 and higher get program updates anymore (completely removed from the pc before installing Kaspersky of course), it would have been possible to get antivirus definitions for the longer future with Emsisoft and Windows 7 just using an older program version but a) I considered 40 euros yearly for a single pc license rather expensive and b) heard good things about Kaspersky of course and just wanted to try it but see above, this German security nonsense is irrelevant to me although I live in this not so wonderful country, still using Windows 7 may seem strange but I have my reasons for it and do not need other versions for the things I do and I checked that Kaspersky is okay with 7 before buying of course so I really think that this is not the reason for this strange activation problem but what else.. So how to continue, asking the support for an activation code and try it ? I do not know if you are in the official Kaspersky support or just a helpful person so if you still have another idea I am happy with it but there should be a realistic chance or rather high probability for solving the problem by it, does not make much sense to try this uninstall/new install thing 10 times when chances are very low for a solution by this By the way I cannot imagine that I am the only person with this problem or what about this...
