QSettings does not write in registry after Windows 10 October update

Question

I build an application that downloads and installs various types of software. When installing the software I write some values on the registry. Everything was working fine until recently with the Windows 10 October update. It seems that now my application does not write to registry. Does anyone have a clue or a solution to my problem?

QSettings settings("HKEY_LOCAL_MACHINE\\SOFTWARE\\MyCompany\\MyAppName\\"+softType, QSettings::NativeFormat);
settings.beginGroup(software->getID());
settings.setValue("id", software->getID());
settings.setValue("title", software->getName());
settings.setValue("version", software->getVersion());
settings.setValue("installationPath", software->getInstallationPath());
settings.setValue("executable", software->getExecutable());
settings.endGroup();
settings.sync();
