I installed Windows Server 2016 on VirtualBox, and now I am trying to install DHCP server on my Windows Server 2016 machine, but I got an error. I set this machine as a Domain Controller before, so I thought this situation may cause the error. I searched it on web, and found a solution. Then I deleted some language packages from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageDetect, but it didn't solve the problem. What should I do to solve this?
The error message is:
The request to add or remove feautures on the specified server failed. Installation of one or more roles, role services, or features failed. The specified package is not valid Windows package. Error: 0x800f0805
A screenshot of the error message can be seen below:
