Windows 10: Error: 0x800f081f while installing .NET Framework 3.5 in Windows 10

I have a new Dell Latitude 5501 laptop with Windows 10 Version 1809 on it. OS Build is 17763.379. Drive D is the ISO files for the Windows 10 install. When using the DISM command to install the .net 3.5, I get the same error every time I try. The command I'm using is "DISM.EXE /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\x64\sources\sxs" I have drilled to the file and it's in that directory on my D: drive. I also tried it as a microsoft help site had it formatted without the x64 in the path. The error is 0x800f081f. The source files could not be found.


I even tried extracting the .cab file and pointed it to that and it was exactly the same error.


I have some machine software that I need to install and it requires the .net 3.5 framework. This computer is air gapped, so can never connect to the internet for any reason what so ever.


If anyone has a solution, I'd appreciate the help. I'm about to the end of my experience with this already.


Thanks.

.NET Framework 3.5 installation error: 0x800F081F

Hi, I need to install or enable NET Framework 3.5 to use a program.

Tried several ways but still no go. I read this too https://support.microsoft.com/en-au...lation-error-0x800f0906-0x800f081f-0x800f0907. Doesn't work for me.

Any solution without having to reset windows 10? Thanks.

Net 3.5 framework, cannot install 0x800F081F.


I tried all of the above to no avail. What did work for me was to go to the Windows component option in Control Panel >Programs and Features and check the .Net Framework 3.5 checkbox and the 2 listed under it as well. If I just checked one it didn't work and I got the error code we are all getting. Not sure if this will work for everyone but I have been racking my brain on this and this is the only thing that worked for me.
