vSro mBot Black Screen and Merrorsender (merrsend.exe) Error Permanent Solution

Hello friends,

I will share with you the solution to the annoying black screen problem that many people using mBot encounter while playing Silkroad Online (vSro). Especially when you open a fellow pet, transport pet, pick-up pet or mercenary, it is very common for the bot to suddenly give a black screen and crash with the merrsend.exe (Merrorsender) error.

This error is usually caused by Windows permissions, missing software files, or antivirus programs blocking files belonging to mBot. But don't worry, the solution is quite simple! By applying the steps below, you can permanently get rid of this problem.

Method 1: Quick Cleanup (Deleting the merrsend.exe File)

Let's try the most practical and fastest method first:

1. Make sure mBot is completely closed.
2. Enter the mBot folder on your computer.
3. Find the mrrsend.exe (or merrsend.exe) file inside the folder and delete it.
4. Restart the bot and test whether the problem is solved.

Note: If this step solved your problem, you don't need to proceed to the second step. If the error persists, please apply the permanent solution step below.

Method 2: Editing Advanced Permissions (Permanent Solution)

If the first step didn't work, we need to prevent Windows from triggering this error file. Follow these steps in order:

1. Open your mBot folder.
2. Right-click on the mrrsend.exe application inside and enter the Properties option.
3. Click on the Security tab from the top tabs.
4. Click the Advanced button located in the Permissions for SYSTEM section at the bottom.
5. In the opened window, click the "Disable inheritance" button (or uncheck the box) at the bottom.
6. Confirm the removal of inherited permissions in the warning screen that appears.
7. Close all windows by clicking Apply and OK buttons respectively.

Operation Complete! 🎉

Now, when opening your pets or during your in-game actions, mBot will not give a black screen and crash. You have completely gotten rid of this annoying error.
