How to Verify Game Files and Do a Clean Install for Crimson Desert

If Crimson Desert is crashing, failing to launch, or behaving strangely, Pearl Abyss wants you to use file verification before you jump to a clean install. That order matters because verification is faster, safer, and often enough for corrupted or incomplete local data.

The studio's Report an Issue notice also gives something many generic troubleshooting guides skip: exact save-backup locations for PC, Mac Steam, and Mac App Store. So if you do reach the clean-install stage, you can do it without gambling your progress.

When verification is the right first move

Pearl Abyss specifically recommends verifying files for issues such as:

• the game not launching
• crashes
• glitched graphics
• other gameplay problems that may be caused by corrupted files

That makes verification the best first step for most local client issues on PC.

How to verify files on Steam

Pearl Abyss' official steps:

1. open your Steam Library
2. right-click Crimson Desert
3. choose Properties
4. open the Installed Files tab
5. select Verify integrity of game files

The note also warns that verification can take several minutes, so do not cancel it halfway and then assume it did nothing.

How to verify files on Epic Games Store

Pearl Abyss' official Epic steps:

1. open your Library
2. click the three dots next to the game
3. choose Manage
4. click Verify

That is the full official path. If you are troubleshooting a PC build from Epic, this should happen before reinstalling.

When to move from verification to clean install

Move to a clean install only when:

• the game is fully updated
• verification did not fix the problem
• drivers are current
• background interference has been ruled out

Pearl Abyss frames clean install as a later step, not the opening move.

Back up your saves first

This is the most important part of the clean-install process.

Pearl Abyss explicitly says to back up save files before reinstalling and gives these locations:

PC

C:\Users\[USER NAME]\AppData\Local\Pearl Abyss\CD\save

Mac Steam

~/Library/Application Support/Pearl Abyss/CD/save

Mac App Store

~/Library/Containers/com.pearlabyss.CrimsonDesert/Data/Library/Application Support/Pearl Abyss/CD/save

The official notice also tells players to move those backups to a different drive or external device such as a USB drive before proceeding.

The official clean-install order

Pearl Abyss' support flow is straightforward.

1. Back up save files

Do not skip this. If you are going to wipe local files, your save backup should already exist elsewhere first.

2. Uninstall the game

Use the relevant platform client such as Steam or Epic Games Launcher.

3. Delete residual files

Pearl Abyss says to:

• remove the Crimson Desert folder from your Steam or Epic directory
• delete the local Crimson Desert folder under:

C:\Users\[USER NAME]\AppData\Local\Pearl Abyss\

The notice also reminds you that this folder may be hidden in File Explorer unless Hidden Items is enabled.

4. Restart the PC

This is part of the official sequence, not optional extra polish.

5. Reinstall Crimson Desert

Reinstall through your platform client and then re-test the original issue.

What verification can fix that reinstall sometimes does not

Verification is good at catching:

• missing files
• damaged files
• launcher-side mismatch between your install and the current manifest

If the issue is just a corrupted local asset or executable mismatch, verification is much less disruptive than a full reinstall.

What clean install is really for

Clean install is better for cases where:

• verification keeps passing but the game still behaves incorrectly
• local leftovers may be part of the problem
• you want to rule out a bad installation state completely

It is the "reset the environment" step, not the "I changed one setting and now I am nervous" step.

What to do after reinstalling

After a clean reinstall:

1. update fully
2. test the original issue before adding extra tweaks
3. only restore backed-up saves carefully if your problem involves save-state behavior

If the exact same bug survives even after the official clean-install process, that is the point where Pearl Abyss wants a detailed report, ideally with PERS on PC.

Should Mac players ignore this page?

No. The support notice includes Mac save paths, which is a strong signal that the save-backup part of this guide matters there too. The biggest difference is that the verification instructions on the notice are written most explicitly for Steam and Epic on PC.

So Mac players should still:

• back up the right save folder
• understand the reinstall logic
• use the official report path if the issue persists

FAQ

Should I verify files or reinstall Crimson Desert first?

Verify first. Pearl Abyss treats verification as the earlier, less destructive troubleshooting step.

Does Pearl Abyss give Mac save paths too?

Yes. The support page includes paths for both Mac Steam and Mac App Store.

When should I report the issue instead of reinstalling again?

If the problem persists after updating, verifying files, checking drivers, and doing one clean install, report it with as much detail as possible.
