You are trying to install Defender Pro fifteen in one on your computer. You have Windows XP 32 bit and have uninstalled AVG anti-virus and disabled Microsoft Windows firewall. You keep getting a message that Defender Pro cannot be installed on your operating system.
You uninstalled AVG and disabled Microsoft Windows firewall. You can try booting that computer into Windows safe mode and then installing that application. Power on that computer and immediately start tapping and F8 key until an advanced boot options menu opens.
Select “Windows safe mode with networking” from that menu. Once logged into your Windows desktop then try to install Defender Pro. Also, make sure to check that you didn’t run out of disk space.
If so, then you will want to clean up your computer by removing any unnecessary program files, temp files, Internet cache, etc.
