disable kaspersky self-defense (settings, options, untick self defense)
then close kaspersky totally
then run the .reg file downloaded and click yes to add
then open kaspersky again
remove any previous licenses or expired ones
click "activate beta license"
re enable self defense
and voila!! just repeat the operation every 30 days...
this is for 64 bit kaspersky internet security only, you can edit the .reg file accordingly for 32bit versions
