[QGIS-Developer] Log file? - QGIS not starting

Hi,

Are the dlls inside C:\OSGeo4W\apps\qgis\bin?  Main issue with this error
is generally means "we tried to load qgis_app.dll, or another dll that it
needs and we couldn't find it so here is a poor error dialog"  It's a
tricky one to debug at times. Check that folder first for the dlls and we
can go from there if they are.

There are some other tools you can use to track down what file it might be
missing.

Also, do you have a virus scanner that might be taking one of the files
that QGIS needs to load and moving it away.  We have seen that happen
before with some dlls getting moved or blocked from installing due to a
virus scanner.

Regards,
Nathan
