# Change Edition Issues

## Error 0x80070490​

- In the Home to Pro upgrade process, the script may show the below error in red color:

    Exception calling "_DismSet Edition" with "6" argument(s): "Element not found. (Exception from HRESULT: 0x80070490)"

- This issue often appears due to the installed .Net 3.5 framework.
- To solve this, we need to disable it, to do that, open the command prompt as admin and enter
  `DISM /Online /English /Disable-Feature /FeatureName:"NetFx3"`
- Once it's done, try to change the edition again.
- After the edition change, you can enable .net 3.5 again, to do that, enter,
  `DISM /Online /English /Enable-Feature /FeatureName:"NetFx3"`
