Question – I’m getting the Error 0x800f081f
Answer – If you are getting Error: 0x800f081f . That means the “DISM” program cant find/Access the sxs folder or it can’t find the specific files required for the installation of .net 3.5.It means the “sxs” folder you used doesn’t have full control permissions to the current user or simply the files required for the installation doesn’t exist in the “sxs” folder. To fix this right click on the “sxs” folder and go to properties of it and go to “security” tab and check if the current user have the full control of the folder and it’s contents , If not give full control to the current user. If you are still getting the error try a different copy of the “sxs” folder .
