After the recent patch, the royals files were updated and people had to download new files. However, many people with Windows 7 and Windows XP had issues in relation to launching the game due to the file called "dinput8.dll". I personally double client by using my Windows 10 laptop and a Vmware with Windows XP iso. I was able to launch the game without a problem on my Windows 10, but I couldn't launch the game on my vmware that utilizes Windows XP iso. This was the error I was getting on my Windows XP. I heard people with Windows 7 also had the same problem, but I am not positive if same error occurred with Windows XP. I tried various methods to fix it, but I was not able to fix it. Then, one of the GM from royals told me to remove dinput8.dll and try launching the game. Magically, I was able to run the game without a single problem. So the issue was this file called "dinput8.dll". I am not sure if this file was in the mapleroyals folder before the recent patch but seems like this file is causing issues for many Windows XP and Windows 7 players. I was able to catch and fix this error within 10-15min after the patch, but I recently just met someone who had difficulties launching for more than 2 hours until someone told him to remove dinput8.dll. Therefore, removing this file and updating the current mapleroyals file on the download page should be done asap.
I understand your concern about wanting to remove dinput8.dll from the installation, however it is part of the fix for Windows 8/10 users to be able to play the game. The proper fix for this would be having the installation remove/not install dinput8.dll for users on Windows 7 or lower, which is something we are actually currently working on doing. In the meantime, the fix for this issue can be found in the Technical Help section (and is linked in red above the shoutbox).
Because like I said, it can be done in the same installation, so there will be no need for extra download links based on the operating system.
