For BitDefender Internet Security--
Can I use a 2010 license key to register the 2009 application?
This is a yes or no question. But for those who have waaaaay too much time on their hands, and are curious as to why anyone would want to do this, instead of just installing the 2010 version or the 2011 version...
I recently purchased the 2010 product. It is brand new, unopened boxed product, with a 2-year license for 3 PCs. I purchased it from a legitimate online vendor. The box, of course, has a disk with the 2010 application.
Why would anyone do this, you ask? Well... BitDefender has released the 2011 product, so retailers want to unload their remaining stock of 2010 boxed product. The result is that the 2010 product is significantly discounted. It's still a legitimate purchase, and the license is valid.
I installed and activated the 2010 program on an older laptop. I'm not having any serious problems, but it really seems to be slowing down the overall system performance. The laptop has Win XP Pro SP3, with 512 MB of RAM. This meets the the minimal system requirements for the 2010 application, but the recommended system requirements are 1GB for Win XP.
I suspect that the laptop is performing poorly because of the smaller RAM. (The processor isn't the problem. The laptop's processor is 1.9 Ghz, and this complies with the recommendations for the 2010 version.)
The 2009 version of BitDefender has a minimal system requirement of only 256 MB of RAM. So I think the laptop might perform better with the 2009 product.
Yes, I still have an installer file for the 2009 application.
Yes, the 2009 application that I have is also the same product: BitDefender Internet Security.
