5. Turn on virtualization
Some users have solved this issue by simply enabling the virtualization option on their PC. Before you turn on the virtualization, it is advised to check if your PC supports it.
For Intel processor
- Download the Intel Processor Identification Utility.
- Run the software and click on the CPU Technologies tab.
- Search through the drop menu until you find the Intel Virtualization Technology option. If there’s Yes in front of it, it means your PC supports the technology.
For AMD Processor
- Download the AMD Detection Utility.
- Run the Utility and check if you have the Virtualization Technology. If your system is compatible with the technology then you can go ahead and enable it.
To enable virtualization, access BIOS and turn on Virtualization Technology feature.
6. Turn off Hyper-V
