I’m experiencing compatibility issues when attempting to install Kaspersky 2012 in Windows 8 operating system. How do I fix this?
Kaspersky's site suggests that you can install a patch to make the product run in Windows 8 but the level of protection will be lower than before.
Also, the instructions refer to a PC with an older system, which is being upgraded. It's not clear that you can apply the patch when installing the software to an existing copy of Windows 8.
You could still try applying the patch, but I would suggest you look at the upgrade options to Kaspersky 2014.
Windows 8: Compatible Products
Migration policy to Kaspersky Internet Security 2013
If Kaspersky Internet Security 2010/2011/2012 with an active or expired license is installed on your computer, then you can upgrade to Kaspersky Internet Security 2013. You can also migrate to Kaspersky Internet Security 2013 from Kaspersky PURE and Kaspersky Anti-Virus 2013 or migrate back, if necessary.
Kaspersky Internet Security 2012
If Kaspersky Internet Security 2012 is installed on your computer and you want to upgrade your OS to Windows 8, then before upgrading install patch k.
I don't think you could do that as compatible issues will occur. You may have to get Kaspersky 2013 or just use another antivirus like AVG for example.
