[Qt-interest] Qt Commercial installation on Windows 7

[Constantin Makshin]

Directory virtualization was introduced in Vista, not 7. Most, if not all,  
modern OSes don't allow ordinary users write to system directories, and  
that's good IMHO.

In this case I suspect that manifest in Qt installer doesn't specify that  
it needs admin privileges. If you can, open the installer in some  
binary/hex viewer and search for "requestedExecutionLevel" text (embedded  
manifests usually are somewhere near the end of the file). If there's no  
such text (what means missing or incomplete manifest) or its "level"  
attribute (Windows manifests are just XML files) isn't equal to  
"requireAdministrator", then I suggest filing a bug report.
