You may wish to contact support, but, you should know - we already did, before we responded to you, in our first reply; we don't feel the need to write down every time we scratch our nose or yawn or take a breath, but, if this continues, maybe we'll have to:
Kaspersky experts advised:
"IF you are located in India, you will be able to download the software, from the US site, but you will not be to activate it as the product is not yet released in India. Just like our previous products, Kaspersky Standard, Plus & Premium licenses also have regional restrictions. If you download & activate the software in the USA then bring the device to India, then it will work; if you try to activate US software, while you are physically located in India, the "Activation code is invalid for this region" will happen."
Only FYI , my location is Belgium (EU) and I run Kaspersky Plus downloaded from the UK site with a license purchased on the Kaspersky Netherlands (EU) online shop. For an additional advice please contact Kaspersky Technical Support , the link is available at the top on this Webpage.
Thank you for posting back & the information!
💥As we said in our first reply, this error: "Activation code is invalid for this region" may happen💥
According to @Danila T., the global rollout of Kaspersky: Basic, Standard, Plus, Premium is expected sometime in the first quarter of 2023 - it's better to wait; the US software is designed specifically for the US.
Eventually, when the new software arrives in India, you'll be able to convert (your) KIS license into a Kaspersky Standard subscription, as long as the KIS license is valid and has days remaining.
Also , where did you purchase your activation code ?
[The error "Activation code is invalid for this region" occurs if you attempt to activate the application with an activation code that was intended for use in another country or region.]
