Dell 305w Wireless printer can print but not scan wirelessly

Apologies if I am in the wrong forum for this question and if I am, could somebody direct me to the right one.

This question is two-fold and I'm hoping that somebody has experienced this problem before and knows exactly how to rectify it. If anyone can solve this for me or tell me where I am going wrong, I will bow before them and owe a great deal of gratitude for their knowledge. I have tried everything to get this to work.

My operating system is Windows 7 Professional 64-bit.

I recently bought a new laptop (not a Dell) and so wanted to link this up and synchronize it with my Dell 305w all in one Wireless printer so it prints and scans wirelessly.

I put in the CD that came with the printer and I downloaded the most recent driver (or so I thought).

Anyway, after all that was done it prints wirelessly no problem. The trouble came when I wanted to scan a document from the Dell Imaging Toolbox.

On my old laptop (that is a Dell) and my daughter's laptop (that is a Samsung,) this works wirelessly no problem at all from the Dell Imaging Toolbox. On this new laptop, it doesn't scan wirelessly although it does print wirelessly. Every time I tried, first a message came up giving me a choice of two printers to use yet only one is showing in Devices and Printers in the control panel. So I chose one. (This message never came up before on my other laptop and I never had a choice).

After choosing one, I then chose 'scan' and then 'start' from the Dell Imaging Toolbox. This then brought up another message that was titled, 'Network Scan.' 'For best results when scanning over the network: - Save all your work. - Close Dell Imaging Toolbox. - Press the Scan button on your printer's operator panel.

I need to have it working wirelessly from a remote spot as it did with my previous laptop because I am disabled. Can anybody tell me how to rectify this scenario? What am I doing that is stopping this from scanning wirelessly?

On top of that also related to the printer, every time I boot up the laptop, a message appears saying, 'Microsoft.NET Framework Version 2.0 is required to continue. This software is available for free at - Microsoft website address.'

I've gone to the website and downloaded this twice but the error message still keeps coming up every time I boot.

It would be wonderful if anyone could solve this puzzle for me because I have been trying to solve it myself for ages now.

Firstly, how can I get this computer to scan wirelessly? Are there some settings I need to adjust?

Secondly, how do I stop that message coming up every time I boot the computer?

Thank you

I've already done that.
