Technical Issue: C7 Error Code on Launch

@secondshadowss

Press the windows key , Type "windows update" then click on update history , then at the top you will see uninstall updates it is likely KB4016871 that has caused this.

Something like that should not of occurred,  I am sorry to hear that it did, windows updates like that one are meant to be designed to be rolled back without issue.

In case you need it the Win 10 ISO can be gotten at this link

Okay, so, a friend asked me to play with them in game. I'd been paying monthly for a subscription although I've not actually played in a few months.

I decided to patch up the game and at least peek my head in, but once it finished patching, and clicking to enter, I got error code 7. I've researched this, though most of the posts were at least five years old. Most said to update video card drivers to fix this. I knew my drivers were the latest from Radeon, and so I tried a few other things. I did a scan and repair? Nope.

I tried closing and re-entering the launcher a few times to see if it needed to be updated? Nope.

Then I tried installing the game over my current install location. Not that either.

Finally, I took an annoying and long process of totally uninstalling my radeon's drivers and then after the reset, reinstalling the latest drivers, the hope being the uninstall of all drivers might clear up past driver clutter. After another restart, this also, did not work at all.

I'm frankly getting to be at my wits end, I'd love some help fixing this. I don't think any of my drivers are outdated, as I've tried updating everything in device manager but they all said I had the most current version available. I have windows 7 x64, a radeon hd 7770.. so, my computer may not be the best but it's always been good enough to play this game. 

Oh, and I also do not have bitraider installed that I can see, I used the work around to get back into the game in the past, because all of a sudden bitraider was preventing me from entering the game. I'm getting to the point of considering dropping my subscription. Sure I wasn't playing before, but if I don't even have the option of playing a game I'm paying for, I don't see the point of continuing to pay. I'd really rather not drop my subscription, so please, any help would be appreciated. I've done everything I could think of, short of uninstalling totally and reinstalling the game, I even run the SWTOR launcher's exe in compatibility mode for windows xp service pack 3.

Below, I included a text file for my dxdiag.

While I can't offer much, I had that same problem with my Intel HD 3000 GPU. After much re-installing and other methods (re-installed Windows 7 with recovery disk) I got it working only to load into graphical issues, artifacts, triangles, missing textures. 

A lot of the issues come from the 5.0 update, with even a few threads being posted the TOR forums, but not official response or fix. I just returned to find the issues of artifacts and graphic issues to be annoying. The C7 error, trying seeing what your computer has for its selected display adapter in Device Manager, if it's set to Standard VGA graphics and not what your current GPU should be, trying disabling it and enabling the proper one.

Again, this seems to be all related to SWTOR and not client side, I just hope the devs address it and the artifacting/graphics issues of late o.O

The tricky thing with the C7 error is how vague it is. It's basically the game client (swtor.exe) detecting an issue with either your Operating System, Drivers, or Hardware. It could be something as simple as not having your Windows up to date.

Hardware and driver wise your DxDiag looks absolutely fine, no problems from what I can see. So first thing I'd recommend is running Windows Update, check for updates and install any that are available. Basically the goal is to get to the point where 'Check for Updates' comes back saying "No updates available".

Another thing I'd recommend is disabling any Compatibility Mode settings for launcher.exe and swtor.exe, they should both work with Windows 7, 8, and 10 without these settings. You can leave "Run as Administrator" on though, that's fine to use.

Unfortunately my windows update function seems corrupt, I think it became that way after I stopped an automatic update from windows 7 to windows 10. I knew I didn't like windows 10 because I loathed using it on my laptop which came with it installed, and I'd been telling windows pop ups for months that I did NOT want to upgrade, but one day it decided to automatically upgrade anyways. I stopped it in the process. I knew it was dangerous to do, but I was right in that when I did reboot, the computer fixed its issues and ran perfectly after that, except for this minor issue. 

NOW windows update says I need to restart to install an update, but the only failed updates are for upgrade to windows 10, which I refuse to do, and even restarting my pc obviously doesn't clear the message. I'm looking for ways to clear this from my list, or.. something.

@aeterna85

Right, that may very well be a possible cause.

As far as I know, even after an upgrade to Windows 10, it will offer you the option to downgrade back to your previous OS.

This is kinda straying from a SWTOR issue so it's a bit outside of the scope of support, but accepting all the updates and upgrading to Win10, and then reverting back to Win7 (making sure you take all the precautions like system restore points, reading guides, etc.) might be a possible solution. Once you've reverted it might even stop pestering you about upgrading, and hopefully you'll be able to use the Windows Update functions again.

I'm going to have to post about my issue in several places, I think. The windows update, I mean. If I can't figure this out, I'll have to cancel my account. I can't actually update to windows 10, at least I don't see the option anymore. I'll post here again if I can fix the windows update.

EDIT: Also, uninstalling the game and reinstalling didn't work.

@aeterna85

Has there been any security windows updates recently in your update history ? Have seen a recent windows update cause C7 with AMD video cards however this was on windows 10

What you can do just to be sure the component registry is good is open a command prompt as administrator and type the below and press ok

sfc /scannow
