Hello air320
I wish I could offer advice, but with Monsieur Urs in the conversation, you are in good hands.
My install was done with Bitdefender running. Maybe Kaspersky is more rigid than Bitdefender.
Just make sure you can copy/paste files between folders on the two machines. I am no expert here, I just follow Aivlasoft excellent manuals.
Hope you get your issues fixed.
