0x800f081f Error Messages While Installing .Net Framework 3.5 in Windows 10.


Paste this: Dism.exe /online /enable-feature /featurename:NetFX3 /source:C: /LimitAccess


  1. how to undo it ???
    i have done it and my my game doesnt open instead it shows a pop up of framework.
    where it is written that " unhandled exception has occurred in your application . if you click continue , the applicatiom will ignore this error and attempt to continue, if you click quit the application will close."
    even when i click continue a mini window of game opens with all the options blacked out.

  2. what do I do?
    Error: 8

    An error occurred accessing the temporary folder C:UserssidneAppDataLocalTempBFDDE520-390A-4134-9642-11EEF294F77F.
    Ensure that the path to the temporary folder exists and that you have Read/Write permissions on the folder.

    The DISM log file can be found at C:WINDOWSLogsDISMdism.log

  3. To All Who still having troubles
    Make a New folder name sxs in C drive and copy the ZIp file under that folder and Enter following command in CMD (Admin) and press Enter.
    Dism /online /enable-feature /featurename:NetFX3 /All /Source:C:sxs /LimitAccess
