And after that impossible to cancel the refresh, I have to kill the process.

thats a permission issue. you didnt follow the install instructions correctly.

**How to Install:**

**+** Stop your Torrent from seeding (close it, maybe check your task manager)

**+** Move the Warhammer Online — Return of Reckoning outside the ReturnofReckoning-March2020 folder and move it to c: … for instance move it to c:Games
(but **NOT** inside c: Program Files or c: Program Files (x86); it should be in a folder which it have write access)

**+** Remove the write-protection from all the files in the Warhammer Online — Return of Reckoning folder.
(right click on the War Online — RoR folder > properties > disable the read-only box)

**+** Check that your whole Warhammer Online — Return of Reckoning folder is whitelisted in your Antivirus program and check if your Firewall or Maleware doesn’t interfere with the install.

**+** You may also try running the launcher with Administrator privileges.
(Right click on the RoRLauncher.exe > properties > run administrator)

**+** Run the RoRLauncher.exe
**+** Let it update (sometimes it needs a few seconds until it starts)
**+** Exit launcher and rerun it again
**+** Repeat the last 2-steps until there is no update left
**+** Launch the game

**!!!** [If you don’t have DirectX 9.0c, installed it is required, and now this is also included in the torrent. In the ReturnOfReckoning-March2020 folder find the dx90c folder, open that and run DXSETUP.exe]
