Installer error 16389 for Microsoft Visual C++ Missing DLL: d3d10.dll

[Girasol2016]

Since the latest update the above error message is shown and I can't enter the game. I have no idea what to do and I must add that I am not very good with computers. I hope somebody can help me, thanks a lot !!!!!!

Go to this thread...
https://www.lotro.com/forums/showthr...r-patch-30-0-3
...and follow Bentolce's advice.

Just a note that this seems to be affecting only users of SSG's "Mac Download" package, not users of the Windows client within Crossover.

I am having a similar problem as well after the last update. These are the error codes I am getting:

missing dll: d3dcompiler_42.dll
missing dll: d3dx10_42dll
missing dll: d3dx11_42dll

Also, not on a Mac...running Windows 10. And there is no longer a "userpreferences.ini" file for me to look at and check the settings in there.

Please don't let the solution be "re-install"! I do have the game backed up but, alas, it now no longer has the "userprefernces.ini" file either

Go to your StandingStoneGames folder and find the troubleshooting folder. Run the DXSetup.exe file that's in there and all should be fixed.

KiraLin53 *does happy dance*...Thank you for that fix, Altair6!

I do not see anything like that in my SSG folder. Not sure if you realize you are posting in the Mac area?

They do, but they saw a thread title which matched the problem they were experiencing on their Windows boxes so they joined the two threads here in Mac Technical Support. It's not hurting anything other than causing a bit of confusion.

You do have dxsetup.exe whether you are using SSG's "Mac"/WINE version of the game or the Windows version installed into Crossover.
–Look here if you use Crossover:
WhereverYouPutYourCrossoverBot tles/CrossOver Bottles/Bottles/TheNameOfYourLOTROBottle/drive_c/Program Files (x86)/StandingStoneGames/The Lord of the Rings Online/troubleshooting/DXSETUP.exe
–Look here if you use SSG's "Mac"/WINE download:
~/Library/Application Support/com.standingstonegames.lotro/common/wineprefix/drive_c/Program Files (x86)/StandingStoneGames/The Lord of the Rings Online/troubleshooting/DXSETUP.exe

Crossover users should not need to deal with this problem but if it were necessary it would be easy to run that executable within Crossover.

Users of the "Mac"/WINE download are unlikely to be able to figure out how to run a Windows executable on their Macs using the version of WINE and the type of bottle provided by SSG, and unfortunately they're the ones who might need to do so to repair this problem.

Edit: apologies didnt check that it is Mac related forum. Nevertheless, there should be equivalent solutions.

Might work for someone, tho maybe only for those who didnt patch yet:
Start your game launcher with
-nosplash -skiprawdownload
keys
i.e.

cd D:/Steam/steamapps/common/Lord of the Rings Online/
//or whatever is your game location
lotrolauncher.exe -nosplash -skiprawdownload

Doing so skips that repetetive visual c++ redistributable packages installation (ofc you should have installed the necessary ones beforehands) which was implemented some time ago when DX11 stopped working with 64bit client. Thus, skipping that install which pops on each launcher startup without those keys should at the same time help you avoid any errors of DirectX missing .dll-s.
Which are actually stored in
C:/Windows/System32/ folder
and should be backed up for cases if game does some nonsense like deleting them.
