Witcher 3: Wild Hunt is an extremely immersive action-role playing game that was developed by CD Projekt Red. The game Witcher 3 is a well-known game and is famous in the modding community. The game is highly praised for its open world and amazing graphics, which provide the users with a well-written story and quests that make the game more immersive.

However, users are facing the Witcher 3 compilation error while trying to play the game using Nexus Mod Manager or any other Mod managing tools. In this article, we talk through the causes and how we can fix the Witcher 3 script compilation error.

What Causes The Script Compilation Error Witcher 2?

When your page is unable to compile JavaScript successfully, you will get the Script Compilation error. The most common causes for a script compilation error to occur is if your page has too many script tags or your page is missing a required script tag.

We are pointing out some of the most common causes for script compilation errors:

Faulty/outdated modes: If you are trying to run Witcher 3 game on faulty or outdated mods, you will get the script compilation error. Faulty or outdated mods are not compatible, and such incompatibility doesn’t allow the mods and game to play well with each other.

Outdated game patch: Before you go ahead with installing or applying any mods to the game, you should ensure that the game is equipped with the latest patch. If the game patch is outdated, you will get Witcher 3 script compilation error due to incompatibility.

Corrupted files in the hack folder: You should check if the Hack folder in your system does not have any corrupted files. It is possible that the corrupted files could be installed automatically, so check them out as well. If you find any corrupted files, get rid of them before going ahead with the fix given in this article.

Incorrect telemetry keyword: If any wrong telemetry word has been configured for Witcher 3, the game will give a script compilation error. Thus, you should ensure that you have chosen the correct telemetry word and reconfigure it if not.

Mod versions: The mod you are trying to install and the mod which is required may be of different versions. It sometimes might not give the script compilation error because older versions of mods override some of the features of the latest version.

Mod conflicts: Installing more than one mod can cause conflicts during gameplay as each mod will have a different version and thus might conflict with each other.

Fixing the Witcher Chapter 3 Script Compilation Errors

After understanding the possible causes for Witcher 3 script compilation errors, we will now discuss the possible solutions that we can use to fix the compilation errors from ever occurring in the future.

  1. Remove any faulty mods
  2. Update your mods and the game
  3. Download the Unification patch
  4. Merge mod scripts
  5. Delete the hack folder and then update the telemetry keyword
  6. Workaround using the error log

Solution 1: Remove faulty mods

It is possible that the mods you have installed are contradicting each other and giving the script compilation errors in Witcher 3. It is important that you use mods with Witcher 3 because they provide extra features to the game and enhance the end user’s experience with gameplay.

However, these mods can cause a lot of trouble if they are faulty, outdated, or are interfering with other installed mods on your system. If you have too many mods, identifying which mod is faulty or generating conflict might be a very hectic task.

The most efficient method to disable or remove a faulty mod is to delete the “Mod” folder from Witcher 3’s directory and then reinstall all the mods one by one and check which of them is the trigger.

The solution might be time-consuming, but it will efficiently fix the Witcher 3 script compilation error.

Solution 2: Update Mods and the game

Witcher 3 comes with a Game Of The Year (GOTY) edition. It is important that before starting to play Witcher 3, you have updated the game to the latest GOTY edition and have made sure that all the mods are updated to the most compatible version.

If the game’s GOTY edition and mods versions aren’t compatible, you will get a script compilation error. The incompatibility will also affect certain features of the game.

Here’s how you can fix the incompatibility issue by updating the mods to the latest patch.

Witcher 3 Script compilation error

Step 1. Go to the internet and install the base game Witcher 3.

Step 2. Now go to the following links and download the patches from Day 1 to 1.31 Patch in the given sequence

  • Day 1 Patch – Here
  • 1.10 Patch – Here
  • 1.22 Patch 1.31 Patch – Here

Step 3. Once you have downloaded all the above patches, store them in a single folder.

Step 4. Go inside the folder and install the Day 1 patch first. To do this, double-click on the patch.exe file in the folder.

Step 5. In the open pop-up, click on the Update button.

Step 6. Allow the Day 1 Patch installation to be complete. Once done, repeat the same procedure for all the downloaded patches in the sequence you downloaded, i.e., install them in order of their versions.

Step 7. After installing all the patches mentioned above, your game will now be updated to the 1.31 version.

Step 8. Now download the mods for your game that are compatible with GOTY version 1.31.

After you are done with all the installations, the script compilation error will most likely have been resolved. If you don’t want to install each mod individually again, skip step 8. and follow solution 3.

The solution above should have fixed the compilation error due to conflicting mods and the game. If the issue persists, follow the next solution.

Solution 3: Download the Unification patch for mods

In the previous solution, we had to download and install each version of the game and mod individually. However, if you don’t want that your mods and the game have different versions, an alternative method is to apply the unification patch.

The unification patch was released later to solve these compatibility issues. Before you begin with the solution, please make sure that the game is updated to its latest version by following the steps in solution 2. Here’s how you can download and apply the patch.

Install unification patch to fix mod conflict

Step 1. To get the unification patch go to the Nexus mods website and download it.

Step 2. Once the unification patch is downloaded, Copy the Content and Mods folder from it into the game folder.

Step 3. It would be best if you chose to copy and replace the items and not simply copy them.

Once you have applied the solution, launch the game and check if the Witcher 3 script compilation error is fixed. If the issue persists, follow the next solution.

Solution 4: Merge Mods scripts

The Witcher 3 mods that you have installed don’t need to be all compatible with each other. Sometimes the mods conflict with each other and cause compilation errors which interrupts gameplay.

A third-party software called Script Merger can help you fix the problem by merging the scripts of the mods together and solving the conflicts.

Install script merger software to merge mod scripts

Step 1. Go to this link and download the Script Merger software.

Step 2. Once downloaded, install the software in your system.

Step 3. Launch Script Merger software and click on “…” to browse to and select the Witcher 3 directory from your computer.

Step 4. In the Conflicts section, click Refresh to see all the conflicts between the mods.

Step 5. Please choose the mods that are conflicting and click on the Merge Selected Script option.

Step 6. You can now see the number of conflicts that are present in the scripts. It will also show the conflicts that can be resolved automatically and which need to be handled manually. Click the OK button.

Step 7. You will be able to see A, B, C on top words, which are the names of the columns. If you see below, you can see the output column.

Step 8. The lines colored yellow indicate conflicts that need manual attention in order to be resolved. To resolve them, go to the Output column and scroll down until you find the Merge column option, which is highlighted in yellow. Right-click on the option. For example, from the A, B, C columns, identify which columns have actual code highlighted in yellow and then click Select lines from that column.

Step 9. Once the automatic and manual conflicts are resolved, you will be able to see that the conflicting columns have been used. Please click on the file and choose the Save option to save the merged script.

Step 10. Close the merging window after saving. You will be able to see a message displayed on the screen saying Merge FInished. Click OK on the message.

The conflict between mods is most likely resolved now. If multiple conflicts are occurring in the mods, repeat the above steps and resolve all the conflicts.

In this process, we are solving all the conflicts that arise between the scripts of two different mods. We are merging these mods together so that the game can use the merged script and smoothly use all the mods without conflict.

The solutions given in the guide should be followed in the order that they are listed, as it might affect the script of your game if not executed properly.

Solution 5: Delete the hack folder and update the telemetry keyword

Witcher 3 compilation error can occur if you have configured the wrong telemetry keyword. To fix this, you must delete the hack folder in the game and update the telemetry keyword in Witcher 3.

Step 1. Open the game’s directory and navigate to the tasks folder in it.

Step 2. Inside the tasks folder, delete the hack folder.

Step 3. Now navigate to C: Program Files (x86) The Witcher 3 content content script engine folder.

Step 4. Right-click anywhere in the folder and choose to create a text document. Please copy and paste the below lines in it. Name the text file as “telemetryKeyword.ws” and save it.

}

Solution 6. Workaround using Error Log

When the Script compilation error occurs while launching the game, you should read the error log carefully and note down the file that is indexed in the log. You should also note down the line number specified in the error log where the error has occurred. Once noted down, navigate to the particular file using the path listed in the error log. Delete the line that you had noted down above.

For example, there are two text files listed in your error – commonmainmenubase.ws and maincreditmenu.ws. The error in the commonmainmenubase.ws file is at line 73, and the error in maincreditmenu.ws is at line 397.

Step 1. Go to the game’s directory, navigate to the commonmainmenubase.ws file and delete line 73.

Step 2. After deleting the line, please save the file and close it.

Step 3. Now navigate to the maincreditmenu.ws file and delete line 397 from it.

Step 4. Save this file and close it.

After making the respective changes, relaunch the game and check if the issue is resolved.
