dont know if its abyss or UO tiara or the new update for windows 10 that happened some days ago whichever those 3 the mods are dead on my computer. I launch the game and client.exe will not work. Even in a fresh installation of these mods still wont allow it to launch it also requires the launchers to be ran as admin without mods to even function. I have tried running it with admin rights when mods are in place doesnt work. Strangely enough I also get a error message about abyss now when installing Tiara
If you use mods avoid any launchers at ALL cost. Please do NOT use them. They cause more problems then they solve. Specifically the Nexon Launcher. Say you were to get the latest client and dlls via PowerPatcher... Well, guess what... The Nexon Launcher will revert your fresh, new, and latest files to the older ones it thinks are the correct ones. Even though these files you supplied are the correct ones. This probably has to do with server side settings of the launcher, or within some configuration settings itself. I haven't looked into this yet. I do know based on what PCs I've worked on so far that have used the launcher. One person had been having issues for months... From a logical and common sense perspective it makes sense that the launcher reverts files, it's their way of ensuring nothing is modded. The problem is they take it too far and it's not working as it should. That's Nexon for ya lol.
So, the issue with Abyss can be done manually as it does download the file, it just doesn't extract it. This is something Shaggy is looking into. He mentioned this a few posts back. When you read the past posts as well you give yourself the best chance of getting things running and being able to help yourself. This is important, because we can't always be there and with as many people that do ask for help... It's in your best interest to know. (You should know how to use it, if you're going to do so). I'd start with PowerPatcher--revert your version to 5 versions back. Patch to current to get the latest files. After this you'll want to check your packs and make sure you remove the redundant ones. Every 5 versions they like to bundle typically, sometimes every 2. Then make a direct launch shortcut, use Mabi Direct Launch, or use Mabi Launcher Plus. For info on these please see the respective threads on them. If, you're unable to resolve this after actually trying and what not, feel free to shoot me a PM with Teamviewer info: Time, ID, and the password when you're in front of it. This is a last resort however. I still play so I like to enjoy my time too, and well real life... Good luck.
PS
I use Windows 10 as well with current updates, no issues, as do the others that I've worked on.
