As a wrote sooner is one of my weblogs Windows 7 is being delivered without mail program. Users had to choose an alternative program as Windows Live Mail, Mozilla Thunderbird or Outlook.

One user decided to install Windows Live Mail on his Windows7 computer and had a strange problem this week. When he got a mail with a PDF document attached and tried to open this, he got the following message:

This file does not have a program associated with it for performing this action. Create an association in the Set Associations control panel.

The Adobe Acrobat Reader was installed om the computer and from other programms the Acrobat Reader started without any problem. Just in case I have un-installed and installed the reader  again but this didnt solve the problem. In a last attempt I habe installed a programm called the Foxit Reader (an alternative, small PDF Reader) and guess what... ?   No more problems, PDF documents kan be opened without any problem with Windows Live Mail. 

In some way there is a problem in the communication bethween Windows Live Mail and other programms. The option "send to" e-mail from Microsoft Word does not work without problems. Enough evidence to make the Windows Live Mail part of an investigation.. 

For the time beeing you can use the workaround by installing the Foxit Reader...
