Read windows registry key with Qsettings without creating one

Hello,

in my program I've got the following lines:

Source code

 
1
2

QSettings gnuPGsettings("HKEY_CURRENT_USER\\Software\\GNU\\GNUPG", QSettings::NativeFormat);
gnuPGHome = gnuPGsettings.value("HomeDir").toString();


The program should be protable, so no registry key should be created. Problem is, that with the first line the key is automatically created, if it doesn't already exist. So how can I prevent the creation of this key?

I already searched a lot without any helpful result.

Many thanks in advance for any help.

HKEY_CURRENT_USER\\Software will always(?) exist so you can start from that settings point and check for child group existing for GNU, then check again for GNUPG ...

If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
