I am having a problem installing IMAQ Vision 6.

Hello!
I have IMAQ Vision 6 which I would like to install on my computer. I keep getting a warning that I cannot use the program without installing Microsoft .NET Environment. I checked my system and I realized that I already have the .NET installed. What could be the problem that is associated with the error. I have other applications that also require .NET environment to function and they are just working fine.
