Not able to install Dot Net 3.5 framework on Windows Microsoft 2019 Server

Hello SanketJ,

I am Matt, an Independent Advisor and a specialist technician. I would like to assist you with this and hopefully I can help you to resolve this issue promptly.

Are you mounting an ISO or using a DVD?

I have found the best way to do this is to open your DVD or ISO, lets say it is mounted as E drive.

I use file explorer and navigate to E:\Sources\ then select the "sxs" folder, hold down the "Shift" key and right click and use "copy as path". Then paste this into the windows server installer as optional path.

If that still doesn't work try installing using DISM in powershell using

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess

Hope this helps, if it doesn't let me know and I will give you some more options.

Kind Regards,

Hello Matt,

Thanks for your reply, I have downloaded the setup copy from Microsoft's website. I have tried the DISM method using Command prompt and not on Powershell. On command prompt i am getting error 50.

Thanks and regards,

You can copy the folder however I personally store the iso on the server and right click and mount it as a virtual DVD drive.

Did you get .net 3.5 installed?

Hello Matt,

Finally I have been able to install dot net 3.5 when i received the ISO file of the OS. Thanks for your support and concern.

Thanks and regards,

I have seen that error many times. I found the best solution is to mount the windows server iso as a virtual drive and then point the "additional sources" option to the sxs folder from the iso. This works all the time.

Try run command prompt as admin and run DISM with out providing a source. This should use the online installer.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

If this doesn't work let me know and I will send you instructions for a registry fix to enable downloads from windows update.

Kind Regards,

Matt
