FSDT Installer Not Loading

[virtuali]

Looks like the updater executable is built with the classic .NET 4.8.x Framework, per the Fault data. I have the 8.0.15 .NET Core installed though, which obviously has portability/backward compatability with classic framework apps. (see attached)never had an issue before.

Yes, the updater is built with the 4.8 runtime, so your problem might be you ONLY have the 8.x core installed and nothing else, because if I check my installed runtimes, I have many of them, in multiple versions, like Microsoft.WindowsDesktop.App, which is in addition to the Microsoft.NETCore.App, so maybe you only need to install the missing ones.

The 8.x core has the 4.0x framework portability built into it.

MS switched from the framework to the core to be able to make CLR/CLI binaries portable between OS's and platforms and not windows exclusive.

Nevertheless, I have already validated this issue on another machine running the deprecated 4.x framework SxS with the 8.x core.

Haven't been able to launch the installer UI for 2 months.

Of course, but that doesn't automatically guarantee that *every* 4.x app will work, so you might need to install the "real" 4.0x .NET runtime anyway.

When attempting to install Framework 4.0, Windows displays the message ‘Already exists’.

I don't know what to say, other than it's clearly an issue of your .NET installation-

Try using a VPN, files are not corrupted on our server, it's a local CDN issue.

I recently tried to download FSX GSX and CYVR files to my new Win 11 computer. I had to retry four times because I kept getting an error message, installation failed because Source files corrupted. The fifth retry I got lucky and the files downloaded error free.
My suggestion is, to avoid this issue with Canadian customers, why don't you provide a DVD with the FSDT scenery files to avoid downloading corrupted files off the internet. That would save a lot of grief and time.

If your files are getting corrupted on download, then you have a problem with your computer.

There is nothing wrong with my computer, it works just fine. Cloudflare has a few problem's of it's own.
This is Virtuali's advice.

Try using a VPN, files are not corrupted on our server, it's a local CDN issue.
That's completely outside our control, we just update files on our server and communicate to cloudflare the list of changed files that must be updated, then cloudflare will automatically replicate all its 270+ nodes around the world, and you'll download from the one closest to you, selected automatically by cloudflare.

If your local node hasn't completed replication or got a corrupted file, or maybe you are the first in your area downloading that file, so you are triggering a replication of your local node, it's possible you might get a corrupted file notice, because the file hasn't got there yet, so it might just work later.

I hoped that, after the global AWS fiasco that just happened and brought down half of the whole internet for almost a whole day:

And the even more recent MS Azure outage:

We would stop seeing complain about how we would supposed to do "better" than multi-billions companies that has been struck with service disruptions due to a CDN issues that ( guess what ), won't affect everybody, but only users in the area were the outage happened.

This is Virtuali's advice.

So, have you tried what I suggested about using a VPN ?
