Here are lists of trials I've been going through:
Downloaded the All-In-One under "Primary Downloads". Didn't work. First thing I did was making sure the .zip files I've downloaded was "unblock" by right-clicked under properties and "unblock". Using Avira Anti Virus, usually there's gonna be a warning sign/notification that will pop-up saying this and that the files I've downloaded contains malware and what not but, it didn't. So, I still go to the manage Antivirus and add an the .zip files name under the exception lists. Everything went smooth, where I place the installation file and where I place the .zip file is under D:\ drive. Where I've installed first was on D:\ drive too. After installing I tried out the "Launch after Installation" method and Launcher works fine and it was updating since "Halloween Patch" and so, I tried Launching the .exe through Launcher but, it gave me the "Ragnarok has been Crash" error. I exited the notes, check task manager seeing if there are any unwanted programs running and obviously, nothing was going against the .exe for flkenro. I did a follow up, left-clicked setup.exe and under display or what graphic card, change it from "direct 3DHAL" to my "Nvidia GeForce 1050Ti" and "Full Screen Mode" making sure my display was not more or less than my 1920 x 1080 display settings. I place it to 1440 x 900 x 16. Sound to 2D sound since my speakers are old and I don't think 3D sound makes any differences since any other ragnarok out there uses the same sound track, a 2 speaker mode, 22K Frequency, 16 Bit sound, 32 sound channel, uncheck(❌) voodoo3 users, check(✅) lightmap and enable(✅) fog, sprite detail High and Texture Detail High. Not to mention I've tried changing each compatibility mode from windows XP service pack 2 to windows service pack 3 and visa-versa and enabled Run this program as administrator for the whole setup.exe, fkenro.exe and ForsakenRO Patcher.exe. Also tried following the Troubleshooter instructions and cross my fingers and hoping that the instructions works on manual patching and small installer and definitely all-in-on installer.
Look guys, from my point of view its a bust. Blackout RO didn't give as much trouble when it comes to patching pre-renewal or renewal or trans-jobs in game and I don't see any differences in this one. I've tried Rebirth RO, and Talon RO. Never this bad. I'm here because I wanted to try a different private server that's all. ⌛
