Thank you for sharing this information but we would also like to know the RAM memory the machine has. That's important when installing our apps.
The antivirus can decrease the performance of our installers, can you stop it during the installation process and start it again after that. In case you want to be sure that you are not installing something malicious, please scan the installer before installing.
PS: could you please share the installer's log that you will find in the %TEMP% directory of the machine? There will be a file called bitrock_installer_XXXX.log
