After investigation of this issue, it turns out that this particular issue can occur due to multiple different potential culprits. Here’s a list of shortlisting that might ultimately be responsible for the apparition of this particular issue:
Method 1: Launching the NXT Client in Compatibility Mode
If you end up seeing the ‘Runescape client suffered from an error‘ status message every time you attempt to open the game, there’s a big chance you’re actually dealing with an NXT RuneScape Client incompatibility. This is quite common in instances where players are using an older game build. In this case, you should be able to fix this problem by forcing the NXT RuneScape client to open in compatibility mode with Windows 7. This workaround was confirmed to work by a lot of Runescape players that were previously seeing the error on Windows 10. Here’s a quick guide on how to enforce this potential workaround: In case the same problem is still occurring, move down to the next potential fix below.
Method 2: Clearing the Jagex Cache
If you previously confirmed that you’re not actually dealing with a compatibility issue, the next potential culprit you should investigate is the 2 most important Runescape cache folders. As it turns out, if the problem is being caused by corrupted cached data that are being called by the main Runescape launcher, clearing the 2 cache folders should fix the problem permanently. In case you suspect this scenario might be applicable, follow the instructions below to access the two cache folders and clean their contents in order to fix the ‘Runescape client suffered from an error‘ status message:
Method 3: Updating your Operating System
If the first 2 potential fixes above didn’t work for you, you should also investigate the possibility of a corrupted or severely outdated GPU driver. In some circumstances, this is actually handled by the Windows Update component – this is particularly known to occur with AMD GPUs that are not supported by their proprietary utility (Adrenalin). If this scenario is applicable, you should be able to fix this problem by updating your operating system to the latest build available. This will also install every platform update and GPU update that might end up fixing the ‘Runescape client suffered from an error‘ status error. Here’s a quick guide on installing every pending Windows Update: In case the same problem is still occurring, move down to the next potential fix below.
Method 4: Updating your GPU drivers
If the method above didn’t work for you or you were already using the latest available Windows build, you’re probably dealing with a GPU driver issue. Some users that were previously encountering the same problem have confirmed that in their case, the problem was actually caused by outdated or partially corrupted GPU drivers. In most cases, the ‘Runescape client suffered from an error‘ will appear due to a corrupted dependency. In this case, you should be able to fix the problem by forcing your operating system to update your GPU drivers and the physics module used by Runescape. Here’s a quick guide on how to do this on any Windows computer: In case you’re still seeing the same ‘Runescape client suffered from an error‘ problem even after updating your GPU build, move down to the final fix below.
Method 5: Creating a new Windows Profile (Windows 10)
As it turns out, several users that were also dealing with the ‘Runescape client suffered from an error‘ have reported that in their case, the problem was actually caused by a corrupted Windows profile. Certain programs in your main profile can end up interfering with the normal launch of the Runescape application. But fortunately, you can fix this problem by creating a new Windows user account and using that one when launching Runescape in order to avoid the error code entirely. Follow the instructions below to create a new user account on a Windows computer:
