I found that the Virtualisation Based Security caused the problem. It did not allow me to re-install HAXM.
With disabling the VBS my problem was eliminated directly !
To check the status of VBS-
Go to Search → System information → Virtualization based security ( Status should not be running )
If VBS is running and you want to stop it.
Option 1
Step 1 - Open Windows Powershell as administrator
NOTE: You need (temporary) admin rights.
Execute the below command in cmd.exe command prompt, PowerShell, or using the Run feature.
powershell Start-Process powershell -Verb runAs
This opens the powershell console as an administrator.
Step 2 - Download and run the script using Windows Powershell
Download the disableVBS-file (attachement) and save it in file explorer
Browse to the location you stored the disableVBS-file in File Explorer and copy the path from the file into the Administrator: Windows PowerShell opened in the first step.
Press Enter to continue.
if you see output :
- Reboot your computer to apply the changes
- Restart your computer and check if VBS is running or disabled after the restart.
- Disable Hyper-V in Windows features and run the script again
- Search for " Turn on/off windows features " and uncheck Hyper-V from the list (you need admin rights to perform this action)
- Reboot your computer to apply the changes
- Re-run the above txt file (repeat step 2)
To Verify VBS is running or not ,
- Go to Search → System information → Virtualization based security ( Status should not be running )
If the first option is not working follow the option2
Option2
- Please run the below command in command prompt. Run the command prompt as admin.
bcdedit /set hypervisorlaunchtype off - -> Reboot the system
On My PC I had to use option 2
