Errors from dotnet while trying to install connectify

Hi,
I have been trying to install Connectify, but I keep getting errors from .NET.
It has been a persistent problem in the past, but hasn’t really bothered me up until now.
If a program requires a version of .NET lower than 4, I am greeted with the following error:

Analytics.exe – AL00:Program FilesWIDCOMMBluetooth SoftwareC:Progra…
X00C:WindowsMicrosoft.NETFrameworkv2.0.50727dw20.exe
OK Cancel
I got .NET v2, but was confronted with the following error when trying to install it.

Microsoft .NET Framework 2.0 (x64) Setup
Error: Product already installed
This product is already installed as part of the operating system.
Exit
I guess, it is related to the Bluetooth software. So, should I take that out? I couldn’t find an exact match on Google, but some article said, try 3.5. I did, but nothing changed.
Any solutions?
Thanks.
