it’s been occurring in the same frequency on several of my pc’s located in different homes. But i’m scanning on this one now just to see if anything changes.
Edit: scan complete, no repair required.
i’ll scan another pc later before i log in and see if it’s different.
Natively in NA.
I tried EU and Asia just now and didn’t see it in either.
Okay. Thanks. (I’m not getting that).
Here’s your screenshot for others to see:
Americas player here as well, hadn’t launched the game while it was updating and had this issue, and deleting+redownloading didn’t help at all.
Anyone try a different ISP, VPN, or DNS server change?
Maybe its a routing issue?
I live in the northern eastern part of the US, but no issues for me.
I am playing in NA. I did not try to play before Update finished. I have 2 HC heroes and the message came up when I switched between them. I did not get that message this morning.
BTW, I had another small update when I logged in an hour ago.
Edit: Yes, it still does it when I start a game. It starts to load, then the message comes up and slows down the game load until it is done.
Edit2: Scan complete, no repair needed, still getting the message when I start game.

I am not receiving the DOWNLOADING ADDITIONAL CONTENT message.
I just now decided to check my Europe and Asia Regions out of curiosity. I am not getting the message there either.

What platform? Are those of you affected only on PC?
What programs are running alongside the game?
Is there a chance there is something running the game doesn’t like? Any overlays?
Maybe those of you having the issue should try installing the updates mentioned by TheTias here:
-If you have the VCRUNTIME104_1.DLL error read this
Even though you aren’t getting that error, it could be related anyway?
Yes, this right here is exactly what I see. I play in The Americas server.
I edited my post above. But, to answer your questions:
In fact, I’ve only had one issue that I believe started a little over a year ago. I haven’t mentioned it because I didn’t think it was related or relevant. But, I will describe it now.
About a year ago I would get one of those blue-screen crashes: “Windows ran into a problem and needs to restart…”. I searched the internet for causes, which led me to some steps to take. Mostly the usual: chkdsk /f c:, sfc /scannow and dism /online /cleanup-image /restorehealth. I think you know the drill. Sometimes I would find errors and let them be corrected. Sometimes I didn’t find errors. Also when playing D3 I would be moving along and occasionally the screen would lock up for a second or two. Then, it would clear up.
As time went on, it began happening more frequently. About a week before Season 34 started I decided to run a memory check using Windows Memory Diagnostic Tool. After about 30 minutes I read the message that “Hardware problems were detected.” And I would “…need to contact the computer manufacturer.”
Well, that didn’t tell me much. And, in my mind, I was imagining all kinds of hardware failures that might be involved. I went back on the internet to search for more information. I finally found some articles about a computer memory testing program called Memtest86. I decided to give it a try.
I was testing my 4x8GB 3200MT/s Corsair Vengeance memory modules. During the test, I watched it log in a total of 604 errors!
Rather than testing each individual module, I decided to replace them all. I purchased the exact type of memory: Corsair Vengeance, 2 packs of 2x8 3200MT/s. When they arrived I replaced the old ones and ran the test again.
The test on the new modules PASSED with 0 Errors.
Now my computer (and D3) are running flawlessly. And my computer just had its ninth “birthday” in January. 
Well bad RAM can happen, and I’m quite familiar with that program.
Funny story:
Yesterday, a customer brought me a Lenovo Ideapad that was doing weird lockups and crashing, all kinds of odd stuff. He thought perhaps he had gotten a virus that was causing issues.
I fired it up on my desk, it booted back up which surprised him as he wasn’t even getting into the OS anymore. But after a minute, it went black with blue lines.
I tore it apart while he watched, and I noted it had a single RAM slot, and on-board memory soldered to the motherboard.
After reseating everything and trying again, it continued to fail. Tested the SSD with an external system, it was fine, still had 96% of its health remaining, etc.
Unit was clean, no liquid entry, no signs of circuit issue.
In frustration I removed the SSD and booted to a Windows 11 install stick. Popped the memory test and within a minute, it failed, locked up and had to be powered off.
I removed the extra memory chip, tested again, it was fine. Booted back onto his drive, worked fine, no problems at all.
Aha! I said, bad module!
Swapped the module with a known good module. SAME PROBLEM came back. Tried 3 different modules in vain!
Turns out the slot or the memory controller was bad.
Talk about weird.
But it runs on the piddly 4GB that is built into the board just fine. *shrug
But it does go to show that yes, hardware can fail.
Hiya all,
Did anyone from the Blizzard D3 team officially post somewhere something about this, or give any kind of information or explanation? Because now, every time I start the game, I get a full minute delay saying “downloading additional content.”. Anyhow, someone should at least tell us about it. 3.7 gigs (for me updated) is not a small change.
We have had no information regarding this issue whatsoever.
We are just throwing suggestions at it, trying to see if something will stick. Not everyone is having this issue unfortunately.
And this is caused by the game detecting corrupted data. The reason DTMAce noted that a full uninstall/reinstall (nuking the \Data folder and emptying the recyle bin then relaunch the Battle.net app and clicking Update) is required to resolve this is because whenever the game detects corrupt data, it downloads while the game is running. Problem is, downloading while the game is running, outside of compiling shaders, corrupts the data all over again. It’s a never ending loop. The only way to fix this, if a Scan and Repair can’t do so, is to reinstall the game.
It’s exceedingly rare for CASC to self-corrupt. Degrade in terms of performance, yes, but unless it’s downloading while the game is running, it’s fairly rock solid.
I should point out, that it was a suggestion. And there was someone that stated they had already done this, but there was no change in the issue, so while the idea was a valid suggestion, it may have no effect.
I have no way to duplicate this, since I’m not having this problem. But I also have a few other systems to try it on, and will do some testing this afternoon.
Just for giggles I upgraded the game on my old gaming rig (Windows 7, 2nd gen i7, 32GB DDR3 Asus 980 Strix with a SATA based SSD) to see if it would run okay there. It updated, ran just fine.
*shrug
I guess it still works on older Windows 7 platforms.
I am getting the downloading additional content message as well. I’ve tried reinstalling and am still getting it. It doesn’t really seem to be affecting anything other than a slightly longer load time. Tho I noticed the only primal I’ve gotten so far was the free one heheh
yah i was skeptical of reinstallation due to it occurring on multiple of my pc’s. i just logged in today for the first time and it did give me the “downloading additional content message” on this pc i’m on, so i clean uninstalled and im fresh downloading it again atm.
will update.
Update: after the initial install and allowing it to sit for an hour, i got the “downloading additional content” message on my first log in. will continue to monitor. makes no sense that some people arent getting it.
Ok so I stopped for a few hours, watched a movie, just logged in and now I don’t get that message, wierd.
okay 100% confirmed it still occurs after a completely fresh clean and reinstallation.
BLIZZARD what is this? if this is some anticheat reading my RAM im all for it, delete the cheats imo. But then why are some not getting it? Does it disable if it catches someone cheating because they are already flagged? WHAT IS GOING ON??? it’s clearly not regional either.
So no solution apparently 
FYI and for the record: I get this message too, but only after switching the compu on for the first time. Start Battlenet, start D3, then always after char select, and then when starting a game. Looks likes the game hangs, but after a few mins, I’m in town and can play. If I play a while, quit and let’s say an hour later, I start Battlenet and then D3 again: no message. And again on and off: no message. Start next day: it’s back.
I had a D4 update paused (wanted to play D3 and it takes ridiculously long to download a few Gbs, with 500kb-1Mb speeds, while on Gb glassfiber in the Netherlands, omg), finished that, thought it might help, but it didn’t.
O, and I never had this message before, and I play D3 since it first came out.
