    Hey there @unseen94 ,

    Welcome to the EN Forum :)
    First of all, try to clean your temp files folder. Check here how to do it. This should fix.
    Otherwise, try this procedure.
    Let us know if the problem remains.

    Same problem for the last two days and cannot fix it. I followed all the instructions from the support (update drivers, uninstall, clear dso folder, restart pc etc) but the problem remains:''Error: Failed to downlad a critical file / Failed downloading a critical file (HTTP response error)! '' and other stuff in the text (incomprehensible to me).
    I noticed that when i start the client only the thinclient.exe appears in the task manager (as intended I suppose) but when i start the game and reopen the task manager i see both thinclient.exe and dro_client.exe and sooner or later the error box shows up and the game stops.
    It is really annoying and now in the forum i see I am not the only one.
    Why on earth I see 2 clients in the task manager ?

    Don't delete the files ... it is most probably CDN failure.
    Your best chance is to start the game in browser so the files would download.
    If that doesn't help log in to another server (not test server) and see if the game download files there.

    Hey there people,

    So, it's a general problem affecting many players :( Can you please tell us which server you play in?
    For now, once my suggestions haven't worked, as @trakilaki already suggested, try to play via Internet Explorer.
    We'll pass this issue to the development team and we are sorry for any inconvenience caused.

    Server: HEREDUR

    It seems i have finally fixed it for now by changing DNS address to as suggested somewhere (another suggested change to by this guy www.youtube.com/watch?v=Ba7hg902S70 did not work).
    I have been playing for about 2 hours straight without problem.
    Still i see 2 clients in the task manager :https://imgur.com/a/TfH1TYk which seems odd but the game works so far and a friend who did not have this issue at all also told me that he sees 2 clients in the task manager from time to time , so I dont know about that.

    Status update: This is not a solid fix, I still get the error but only every 2 hours of playing and only once; after I relog i can play for another 2 hours etc. It happened 3 times just after I entered an anniversary map ( atlantis inf3, normal inf3 and another one). At least I can play now if you can call this a satisfying gaming experience.... In between I might get some nebulas which make me very happy now when I see them :p:p:p:confused::mad:o_O:p

    The same problem here, 4 days now and i cant play.
    I reported it in support, but i dont take a feedback.

    I do not see how different DNS would ever fix a such issue, unless those you are using are unreliable for themselves.

    Try to do as trakilaki suggested above or, using the client, be sure that it completely downloaded all the files before to start the game. I receive this error message rarely and mostly after release upgrade, if i start the client while download is still in progress.

    Folks here is the file you couldn't download (I couldn't see more files in the screenshot above).
    The file is clean and not infected by a virus ... Chuck Norris approved.
    Download it ... unpack it and place the file inside DSOClient folder.

    A further thing, which I did not write about because I did it weeks days ago and then I had forgotten it.

    Starting with Windows 10 build 16232, controlled folder access is introduced in Windows Defender Antivirus. This means that access to the work folder is forbidden to all those software that Microsoft does not automatically consider friendly (its owns) and therefore a notification is produced that warns that the system has prevented changes by the application (but most of users just ignore it).

    Maybe it won't solve your issue, but anyway I'd recommend adding DSO (both thinclient.exe and dro_client.exe) to Windows Defender exceptions, and then try playing again.

    For those who did not know it, dro_client.exe is placed in \Users\%username%\AppData\Local\Temp\DSOClient\dlcache

    Thanks. I downloaded it and put it in DSOClient folder... where it actually wasn't, although I dont remind to have seen any error in this regard. Who knows how many other files I still miss...

    Hey there heroes,

    Rest assured that we are reporting this issue.
    For now, you have two options:
    1. Download the missing file that @trakilaki posted above (I forgot to mention that this issue happened some months ago and this procedure worked in my case) :)
    2. Or... you'll have to wait for a hotfix in near future.
