Installer issues

The installer doesn't start

  2. Depending on your computer, it can take some time to start; wait patiently.

The install stops at "data.grf"

  • Data.grf is the biggest file in the installer; the installer is working, but it doesn't show the progress (wait a few minutes).

"Your game executable has been modified or is not the latest version"

    Solution: Run the Valhalla.exe and wait until it patches.
  • Problem: Your game is not up to date, but you patched.
    Solution: Disable your firewall/antivirus during the patching or add the exe as an exception.

Client issues

Cannot init d3d or grf file has problem

  • Ragnarok has a maximum resolution of 2048 x 1536. This cannot be changed due to Ragnarok being based off of Direct X7.
  • Ensure your monitor's native resolution is set to 2048 x 1536 or lower. On some machines, this requires a computer restart.

I can only see RGB Emulation

  1. This fix only applies if you only see RGB emulation in your Setup.exe's list of Graphic Devices.
  2. Simply uncheck "Disable hardware-accelerated graphics" and it should give you new options in the list of Gracphic Device.
  3. Select the first option in Graphic Device (which should be Direct3D HAL).

I want to play on a Mac / Linux operating system

  • Mac and Linux are unsupported. Compatibility libraries such as WINE, CrossOver and similar will all fail.
  • There are 2 options to play Valhalla on a Mac or Linux machine:
    1. Virtual Machine: Install a Windows OS on a virtual machine. Example of virtual machine software includes Virtual Box, VMware, Parallels, etc.
    2. Dual Booting: Install a Windows OS on a separate partition of your hard disk. This can be done using partition management software, such as Boot Camp or GParted.
