KAV Installing issue...

[lello.siddi]

Hello, my friends...
I won here a KAV 2012 license last november. I installed KAV, but I experienced some instability problems, and so I decided to go back to AVAST! (I had a license for it as well).
AVAST! is going to expire in few days. So I decided to give another chance to KAV 2012. I've unistalled properly AVAST (safe mode with the removing tool). Here is what I get when try to install KAV 2012: http://goo.gl/4klsS.
I also did what is suggested by KAV in the end, but nothing changed. I've read some threads around and have run a tool to remove any trace of previous KAV installation (kavremover.exe), but nothing changed.
In the meantime, I've installed Immunet 3.0.
Does anyone know what is happening? The final warning message says: "Internal Error 2753. avpinst.dll".
Chreers,

A couple of things:-

Did you use the latest Kaspersky remover in safe mode? Apparently it can make a difference.
Try Appremover. This error you're getting is usually a conflict with old Kaspersky leftovers. Appremover can help to get rid of all sorts of leftover security data.
If it still doesn't work, try the Kaspersky GSI Parser to scan your system and report back any possible problems preventing the install.

One last thing, if that's a personal key in the video, you should remove it and perhaps post a few screen shots here instead. Anyone can use it otherwise!

Oups... What an oversight!
As for your advices, I am going to check if they work. Many thanx...

Nothing worked out. And since KAV was giving me problems since the beginning, I'm not trying anything else.
That's really annoying. As you said, it's usually related to issues with old kasp. left overs. They should do something to solve this...
I'm going to switch back to AVAST!. The free version...
Thanx anyway,
