Do you use Windows 7 ?
OK, can you tell me, how do you generally access email from Windows 8 ? like using Internet Explorer or Windows live mail etc. ?
Do you mean Google Chrome ?
Do you use Google Chrome to access emails from the Vista PC also ?
I don't think you are using any of them on Vista, because the problem you are facing is only caused when you do not use any email program, like Windows Live Mail or Outlook to access your emails, you cannot attach the scanned files in emails, until you use the web interface to access emails.
Now, the solution is , you have to configure a email program to access your emails then, you can solve the problem.
I can remotely connect with your PC and help you to solve the problem.
Otherwise I can give you steps here and you can follow them to configure the email program.
Can you tell me, what email service do you use, like gmail, hotmail, yahoo etc. ?
OK, I am giving the steps to configure the email program, if you think that, you cannot do this or face any problem after doing this then, just let me know and I will try to solve the problem by remote session.
First download and install Windows Live Mail and reply me back.
OK, just open it and let me know, what do you see ?
Do you see any window to enter your email address and password ?
Hi, are you there ?
