Troubleshooting Install issues
Error: Failed to unpack Windows 10 IoT Core installation package
If your installation fails with the above message then you need to run the
setup.exe using the Administrator account. This error message could appear even if you are logged in as a user who has administrator rights; it has to be the
Administrator user.
Please note that by default the Administrator account is disable in Windows 10. You need to first enable the Administrator account. The easiest way to do this is:
- Open a command prompt and run the command lusrmgr
- Click on Users in the left pane, then right click on Administrator user and select properties.
- Uncheck the box "Account is disabled" and Click OK.
- Right Click on Adminsitrator User again and select set password to set a new password for this user.
- Now log out and log in as Administrator user and start the install.
