While trying to install or update Myst Online: Uru Live (or a related shard), you may be unable to proceed because of some type of error, especially on Windows 10. Here are some of the most common ones and their solutions:
The “Another copy of Uru is already running” error means a previous session did not close correctly. Open the Task Manager (
Esc), look for “UruExplorer.exe” and click on
If the client is failing to complete “initializing patcher”, it’s because it’s unable to replace itself (
UruLauncher.exe), usually because the game was installed in the UAC-protected
C:\Program Files (x86)\ folder. Reinstalling the game with the latest installer should fix the problem; moving the Uru Live folder somewhere else should also work. A telling symptom is the presence of a UruLauncher.exe.tmp file in the game folder.
A stack dump error (“URU has experienced a serious error”) probably indicates a failure to initialize PhysX: it is advisable to install the Legacy component.
The error related to
d3dx9_27.dll can be fixed by installing a few extra DirectX files. The install procedure is a bit unintuitive: you will have to download the installer, make a new folder on your desktop, run the installer and tell it to extract into the folder you created, then run
DXSETUP.exe from the folder to install the DLL files. If it worked, you can delete the folder on the desktop and the installer.
A Windows 10 update from 2017 broke the way moving with the mouse works: the avatar keeps skipping back to center when trying to turn. The problem has been fixed on MOULa, on the Gehn shard and on Minkata, but is still present in the The Open Cave; to fix it, you can use Sirius’ fix.
