Question

I can't install or uninstall a game, on Epic Games, which had an incomplete instalation in a missing disk.

I am having trouble installing GTA V.

Some time ago, I had a secondary Kingston SSD (H:) on my computer. I tried to install GTA V on it once, but it ran out of space and threw an error, so I canceled the installation.

Recently, I upgraded my computer with a new secondary SSD, a SanDisk (G:). Then I took the Kingston to upgrade another computer of mine, and already formatted and installed an OS. In other words, no recovery from the GTAV's half-instalation files.

Now, the GTAV appears on my Epic Games library as incomplete download, asking to either resume the download, or, letting me uninstall it:

When I try to resume, I get this error screen:

Error Code: DP-OS-F

If I try to uninstall, it opens this screen:

Error Code: IS-0002-DP-OS-F
I have the options to Restart🔄️, Cancel❎ and Options [...] (which includes 'Manage').
Clicking Restart🔄️ throws the exact same error screen shown above.

Clicking Cancel❎ gives me this error message:

Clicking Manage takes me to this screen:

If I click Verify Files, the window just closes. Clicking Uninstall attempts to really uninstall, but fails and returns to the "Install failed at 100%" red text.

The📁🔍 (Open Install Location) button does absolutely nothing.
I have already tried the following solutions with no success:

Uninstalling and reinstalling the Epic Games Launcher.
Deleting C:\Users\[MyUser]\AppData\Local\EpicGamesLauncer\Saved\webcache_4430 and rebooting.
Deleting
C:\ProgramData\Epic\EpicGamesLauncher\Data\Manifest and rebooting.
Granting "Full Control" in the Security tab of EpicLauncher.exe properties (my system language is PT-BR):
Deleting absolutely all Epic Games-related folders, uninstalling, and reinstalling.
Opening regedit (Win + R) and deleting absolutely all keys, registries, and folders where "GTAV" or "GTA5" appear. None of this worked. This makes me think Epic Games is recovering a failed installation state from the cloud every time I reinstall the launcher and log in.
I tried creating a virtual disk mapped to C: to fake the old H: drive (the letter of the old Kingston SSD) using the command prompt:
```
   subst H: C:\
```
I then tried to resume or uninstall the game, with no success. Then I reverted it with:
```
   subst H: /D
```
Finally, I wiped out everything Epic-related again (folders, installations, registries), rebooted, reinstalled, and this time logged into a friend's account who doesn't own a failed installation of GTA V. Still no success. The failed installation showed up on his account on my PC as well.
And also tried to contact Epic Games live support chat. They just guided me through step 4 again and told me to contact Microsoft Support if it didn't work, offering no further assistance. That's why I am posting here. Any help would be greatly appreciated!

Hi Vitor Hugo Leite,

It sounds like the Epic Games Launcher may still be referencing installation data from the previous drive, even though the original SSD is no longer present. Since you've already completed extensive cleanup steps, you may want to focus on checking for any remaining drive-path dependency rather than repeating launcher reinstalls.

As a workaround, try temporarily assigning the old drive letter (H:) to an available volume through Disk Management, then reopen Epic Games Launcher and attempt to remove the incomplete GTA V installation entry. If the launcher can access the expected path again, it may be able to clear the stalled installation record.

You can also run Microsoft's Program Install and Uninstall Troubleshooter, which is designed to remove orphaned installer records that standard uninstall processes may not detect. This can help if a broken installation reference is preventing the launcher from completing uninstall actions.

Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.

Thank you for your time and for trying to help. Actually, the solution you proposed made things a bit worse. I assigned the drive letter (H:) to the secondary SanDisk SSD I mentioned, but it messed up the Epic Games Launcher. Every time I launched it, it showed a message saying something like "The software system needs an update", along with a countdown timer before closing.

However, I managed to solve the problem, but it required sharing credentials with a trusted friend and logging into each other's accounts.

I will post the solution I found in a separate reply. Although it worked, since it involves sharing sensitive data, I will not mark this thread as [SOLVED] so others don't think it's an official or highly recommended fix.

But once again, I really appreciate your help!

Hi Vitor Hugo Leite,

I'm relieved to know that everything is good to go on your side.

It's useful to know that reassigning the original drive letter did not help in this case and instead introduced additional Epic Games Launcher behavior. More importantly, your findings suggest that the launcher may have been retaining installation information that was not fully removed by standard cleanup methods.

Thank you for taking the time to share the outcome and the detailed steps that ultimately resolved the issue.

Finally, after all these attempts, I managed to solve this issue. However, it involves sharing your Epic Games credentials with someone you fully trust and approving their login (if you have Two-Factor Authentication enabled).

Based on the theory I mentioned earlier—that Epic Games saves the state of a corrupted installation in the cloud—we need to force a reset of that state. I was able to do this using the following steps (assuming Epic Games is installed on your (C:) drive):

Uninstall the Epic Games Launcher.

Delete any Epic Games-related folders located in these paths:

C:\ProgramData

C:\Users\[MyUser]\AppData\Local

C:\Users\[MyUser]\AppData\Local\Temp

C:\Users\[MyUser]\AppData\LocalLow

C:\Users\[MyUser]\AppData\Roaming

Run a search for "Epic Games" in the root directory of your (C:) drive and delete any remaining files or folders.

Ask a trusted friend who already has GTA V installed (via Epic Games) on their own PC to log out of their account and log into yours.

Reinstall the Epic Games Launcher on your PC and check the status of GTA V. After step 5, the game finally allowed me to install it properly. If this doesn't work for you right away, I suggest logging out on your PC and asking your friend to start the uninstallation of GTA V on their PC while logged into your account. This might force Epic Games to update the installation status in the cloud.

hello, i'm having the exact same issue you had but with Fortnite. In my case, the installation was completed in an SSD i don't have on me at the moment, so Epic Games seems unable to manage the game files in order for me to uninstall it. I tried all the same steps you described both in your original post as well as in your solution comment and yet i still have the same error. I was wondering if by any chance you had any idea which other steps i may take in order to be able to install the game again, this time in my native C: drive. Thanks for the post !!
