I tried that. It says restart now or restart later. I hit restart now. It doesn't fix it.

I see some stuff with the "Bad download source" thing and my ISP's name too. Is my ISP blocking my Steam downloads for some reason? I am really confused.

Changing download region does not fix it, clearing download cache does not fix it, uninstall and reinstall does not fix it, etc. I am running out of ideas.

Any other time I had an issue downloading/updating games, I checked content_log, found the files that needed to be deleted and redownloaded, and everything worked.

This time is different. This time the weird "Marking bad download source" error seems like it is pointing me to Steam and my ISP. Why would my ISP be a "bad download source?"

Let me guess, the problem started 5 days ago or so?
Same here, games that require VC Redist 2022 just refuse to download. And break my entire library in the process

The problem is with depot 228989, let me know if you see this in logs.
And yes, I'm runnind Win7.

Still no luck

147803_0x1AED94_ST76561197984737819 it flashes white now and gives me this... when I try to run troubleshooter WINDOWS crashes the troubleshooter? I had not played for about say 1 week.... today I hooked up my old htc to try VR - Star ware Squad works perfect Serious sam vr works fine vr but this started then after clearing my DL cache reboot and reinstall not even NORMAL boots... every other game I have works fine can anyone help????

Windows 10 pro 64bit - btw

I'm having the same error. I have around 8 games that all fail and show "corrupt download". Steamworks Common Redistributables is now also "corrupt download" and this is preventing me from playing games that were previously working and have no current updates.

On Win 10, 64bit. This has been ongoing for weeks for me and, as my games put out updates, I'm just no longer allowed to play them.


Troubleshooting Done:

-Cleared download cache

-Changed download region (normally it's Minneapolis, MN. I've tried different states around the

US and well as UK and other random countries)

-Logged out and in again

-Turned off "Game File Transfer Over Local Network" setting (at this point, every option under Downloads is turned off)

-Tried deleting and reinstalling a game and now that game won't install. Deleted folders for it and all. Still "corrupt"


Like OP, when I open the logs>content_logs.txt, it's showing a bunch of "Marking bad download source" errors.

Additionally, I've tried deleting the appmanifest files listed in the logs, and this does nothing.


Some of what I'm showing in the log file:

Having the same problem. WTF is going on?
Just bought Space Marine 2, but cannot donwload it.
Other games cannot update

I uninstalled Steamworks Common Redistributables, and it uninstalled ALL of my games. I cannot reinstall any of them that previously kept having the "corrupt download" problem. But I guess it's just as well, since I can't play those 20+ games anyway.

To put it simply, I will not be purchasing any more games on Steam until they resolve this issue. This also makes no sense, that we cannot update or play the games we've already purchased! If Devs come out with an update to a game, you're screwed.

Yep I can't get the Steamworks Common Redistributables either. I won't be spending any more money either until they fix it. It has broken a bunch of my games. Some still work. I had to fight to get the Tomba remake to download. I guess that'll work until an update breaks it.

How many of you are using Win 7?

Still having the same problem. People are having trouble regardless of OS.
