    Error > Unable to decrypt and de-serialize the data downloaded from the server

    Earlier this morning (about 8 hrs ago), I launched LOTRO client, and it patched up to Update 6 (since I've not been online for a month). Everything went fine during the update process - no errors, nothing wrong, completed successfully.

    I then logged into the game, and was able to get online, load my characters, and play through a few of the new Epic storyline quests with no problems.

    Now, about 8-9 hours later, I tried launching the client and logging in again (with no changes to my system or anything new installed), and suddenly I'm getting the error below:

    Game Update Progress:
    > Connect - Done
    > Examine Programs - Done
    > Update Programs - Done
    X Examine Game Data - Retry (00:29...28...27...)

    "An update error occurred: Unable to decrypt and de-serialize the data downloaded from the server."


    What gives? How do I fix this? It's been re-trying for 30 minutes now...

    Did you bother to use this sub-forum's "Search Function"?

    For if you did, you would have found a thread that explained exactly how to fix this issue.


    Happy searching!

    theres 2 possible fixes for your error but first try restarting the launcher, making sure the icon has gone form the task tray and from task manager before restarting

    then if you still have the same problem browse to your lotro install folder which defaults to c:\program files\turbine\the lord of the rings online\
    program files(x86) on 64bit windows
    find the 4 folders patches, forward, bindat and raw. if any of the folders contain anything delete the contents
    note: some of the folders may already be empty
    restart lotro

    this last option is the most distructive but this usualy occurs during patching
    browse to your lotro install folder and rename both client_highres.dat and client_highres_aux_1.datx to .old, this will mean lotro is not able to recognise the files and you will loose the highres textures... this is what we want
    start lotro, if lotro works now and if the feature still works and im not sure if it still does but you may beable to force lotro to download the highres textures again.
    from ingame options, graphics, select ultra high from overall graphics quality. if this feature still works lotro will tell you it needs to restart then it should download the high res-textures
    failing that you will need to use the High Resolution Client Repair Tool
    once finished you can delete the 2 .old files

    Thank you kindly, Finglonger. For some reason sub-topic searching kept bringing me back to the entire forum list ALL day yesterday - would never actually return search results. Your solution worked great, and today as the prior poster had suggested, using sub-topic searching did find me posts with the same advice.

    Appreciate your time helping this ol' girl out. <3

    Exclamation Re: Error > Unable to decrypt and de-serialize the data downloaded from the server

    I have the same problem, and followed the steps given above. But still it is not working... could someone please help me. I do not use the high-res client, and therefore cannot (?) use the repair tool. I am using a Windows XP laptop. Could this be my internet or is it something else?

    Re: Error > Unable to decrypt and de-serialize the data downloaded from the server

    After update 6, I got this same error. I read from someone else on the forums to change the "client_highres_aux_1.datx " file to "client_highres_aux_1.org" , this worked for me. But now update 7 (May 14th) just launched and I got the same message again. I followed your directions and tried it. None of them worked. Do you have any new suggestions?

    Thanks!

    Re: Error > Unable to decrypt and de-serialize the data downloaded from the server

    I had that error yesterday after losing my connection and then stopping and restarting the launcher.
    Fortunatly I have a second full copy of LOTRO on my computer (I was playing with dual logging a FTP account).
    That second copy ran through and updated fine.
    I then started copying the updated .dat files one by one and then checking the launcher.

    It turned out to be the regular (Largest) Hi-rez file. for some reason if this file is stopped during download the launcher will go into the Unable to decrypt and de-serialize loop.

    browse to your lotro install folder and rename both client_highres.dat and client_highres_aux_1.datx to .old, this will mean lotro is not able to recognise the files and you will loose the highres textures... this is what we want

    I've had this problem a few times but doing this ^ has always fixed it. I had the problem again with update 7 and changed the names again and it's downloading normally again. I run into this problem because my internet like to cut out .

    Not exactly sure how to quote the guy but that info can be found by scrolling up to Finlonger_UK's post.

    Re: Error > Unable to decrypt and de-serialize the data downloaded from the server

    Okay, I went through my LOTRO folder and opened the folders; "bindat" "forward" "patches" and "raw" and deleted the contents. Then I restarted the LOTRO launcher and it didn't work (tried rebooting computer as well, no luck). Then I went and changed the two files "client_highres.dat" and "client_highres_aux1.datx" to "client_highres.old" and "client_highres_aux1.old". Still no luck. I also tried renaming "client_highres_aux1.datx" to "client_highres_aux1.org" like before when update 6 launched. This too didn't work.
    Does anyone have any different suggestions on what else I might be able to do to get it working?

    Thank you.

    Really? You put down your toolbag and took the time out of your incredibly busy day to post that? Wow.

    Thank you, however, to the folks that took the effort to try to help us with this issue.

    I've tried everything you people posted a few years ago, but still then I can't play bullroarer, I know this is for the main lotro client and not for bullroarer but I've this error, well I did delete the files in those 4 folders, then I use the bullroarer laucher and I get this error. I did install the version of Akamai NetSesssion, that some1 putted here, but still tho didn't work.

    Does anyone have instructions for fixing this problem on a Mac? I'm running on Sierra OS, version 10.12. I checked the Mac Technical Support forum, but no luck.

    Thank you!

    You need to ask on the Mac Technical Forum not the Windows Technical Forum. That is because the Mac and Windows version have their own unique issues and solutions. In some cases, the two versions may have the same issue but the Mac and Windows version will hava different solution.

    There is chance this version:
    http://store.steampowered.com/app/212500/
    will work for you. There should be both the Mac and Windows version of the Lotro software.

    Generally the Mac version has more problems than the Windows version
    Unless stated otherwise, all content in this post is My Personal Opinion.

    I have the same error. Apparently, this has been happening since 2012. Has there even been a single reply from tech support?

    I want to play the game. This error prevents me from doing so.

    No, there hasnt; but there HAVE been about a BAZZILION threads explaining the various causes and ways to get around them posted by forum members.

    The best is Hurins "One Guide" thread; if you have followed that and are still having issues, the next most common are firewall or AV issues.

    Just a thought regarding this problem on Windows 10.

    I've had a couple of other programs refuse to update when they were installed in the Program Files (x86) directory. Moving them to their own directory solved the problem. Just wondering if people suffering from this problem on Win 10 have Lotro installed in the Program Files (x86) directory?

    Well worth a try; I got really leery of putting anything in an OS created folder after M$ managed to delete everything in the "My" folders during an update many years ago.
