Answer: What is aeRO Medic?

aeRO Medic compares your local files with the files on our server. Normally, an admin or GM updates this regularly after creating a new patch. It also detects various issues such as compatibility problems or clients running without admin privileges. This app helps you quickly fix these settings.

How to Install?

1. Go to your aeRO folder.
2. Install RO Medic inside your aeRO folder.

Example:

aeRO.exe
PlayaeRO.exe
BGM/
RO Medic/

3. Open "aeRO file check.exe". You will receive a prompt message to confirm your aeRO installation directory. If it is correct, press OK.
4. The app will then compare your files to the ones on our server. If there is a discrepancy, you can press the "Fix and Replace Files" button at the bottom. This will fix/replace the files that differ.
5. Ensure all your "setup.exe", "aeRO.exe", and "Play aeRO.exe" files pass the test. If not, click the fix button.

Solution 1: Unable to update the client due to restriction access.

Run your "Play aeRO" with administrator access.

Solution 1: Install the latest mini installer.

All old installers have been discontinued and will no longer get our latest patch.

Solution 1: Unable to continue with the patch because your aeRO.exe is in used.

Make sure to close your aeRO.exe client when you open the aeRO Patcher.

Solution 1: You installed the mini aeRO installer in the wrong directory. The mini install is not a standalone installer, it requires the aeRO Full Installer or existing RO to run.

So make sure that you install the aeRO Mini installer in the same directory where your Ragnarok or aeRO Full installer was installed.

Solution 1: Check if you have an anti-virus installed on your computer. Add the files that are required to run aeRO to the whitelist(This can be different anti-virus program).
If you have no idea about whitelisting an app, just remove your anti-virus or anti-malware and reinstall your aeRO Mini Installer.

Why do you need to remove the anti-virus? simply because your antivirus is falsely detecting aeRO.exe to be harmful software. What it does is that the client has an anti-cheat program that stops users from cheating.

Solution 1: 1. Download and install the latest Mini Installer on the same directory of your aeRO Folder.

Solution 1: 1. Right click your setup.exe and choose "Troubleshoot Compatibility".
2. Choose "Troubleshoot program".
3. Choose "The program worked in earlier versions of Windows but won't install or run now.".
4. Choose Windows XP(Service Pack 3).
Now try to run the setup.exe and see if you can select the resolution now.
