Open Rails fails to install .Net 3.5 on Windows 10

[Edwin]

I had to reinstall the Windows 10 on the computer that has MSTS and OR on it.
A Windows 10 update borked the permissions, effectively locking me out of the operating system.

So I put in a new M2 SSD and a fresh install of Windows 10.

However, when I try to run the old Open Rails that is on a different partition, it wants to install .Net Framework 3.5.
This install from the ' Turn Windows features on or off ' panel fails every time error code 0x8007002 "The system cannot find the file specified", the same happens when I try to install the Telnet client for instance, so it could be a pathing or permissions error.

Anybody able to help?

I thought this latest win10 update moved infrequently used or non-essential win 10 system files up to the cloud (onedrive). Mumble something about the bloat of the OS beginning to exceed early small SSD sizes that too many users still have.

Microsoft on installing .Net 3.5 manually in Windows 10: https://docs.microsoft.com/en-us/dot...-35-windows-10

Most methods will involve working with the command line or Powershell.

I remembered to have used OOShutup to " silence " W10 phoning home etc, but perhaps with too aggressive settings.

So I used the built-in refresh function to re-install W10 and now the .Net 2.0 etc required by Open Rails downloaded and installed normally.

Seems everything is back in full working order.
