First: Congratolation for this great job your team has done (excuse my bad english), after some (very)
few changes in the #includes, the releasecandidate works fine. For me as a bcb (bloody c++ beginner)
this was a phantastic result! Thaks again.
Second:
Final version: During installation, Bitdefender reports: found infected file 2013-01-31-15:17:20
"Bitdefender hat ein infiziertes Element erkannt in c\qt\qt5.0.1\5.0.1\mingw47_32\bin\designer.exe.
Virus name: Gen:Variant.Kazy.2084. Dieses Element wurde zu ihrem Schutz desinfiziert..."
(For your protection, this element was desinfected...)
at the same time:
Qt-Installer reports (at aprox. 94%...97% of installation) an error:
Error during installation process(qt.501.patcher):
The output of C:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin\qmake.exe -query
is not parseable. Please file a bugreport with this dialog
https:// bugreports.qt-project.org.
output: ""

Third: I did think that it is not a real virus but a false alarm. But trying again
from a second download with BitDefender inactive(to be shure that BitDefender
did not desinfect the download) the same errormessage occours (this time without
Bitdefender)
