[Qt-interest] Windows 7 and VirtualStore woes

[Constantin Makshin]

This may sound somewhat rude, but the standard way to solve self-updating  
problem is to not do it. It's better to implement notifications about new  
versions of your program. Something like "There's a newer version of Foo.  
Do you want to download it? <Yes/No>" and when the user clicks "Yes"  
button, open web page where [s]he can download new version of your program.
