Thanks! This solution worked for me too. For those who can’t find the option, you can also check the ‘uninstall’ section and click ‘modify.’ The debugging tools are the second option. =D Thanks again! ---

In UE 5.4, the error reads as follows: ```auto Unable to find installation of PDBCOPY.EXE, which is required to strip symbols. This tool is included as part of the 'Windows Debugging Tools' component of the Windows 10 SDK (https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk). while executing task ``` Sadly, it looks like the link to the Windows SDK in that message is broken/stale/incorrect. Anyone know the best way to let Epic know it should be updated? ---

I just had this exact error in UE 5.4.2 and the suggestion from @uexilon fixed it for me. ---

Unanswered stuff again, here we go. Its because you dont have debugging symbols for Windows SDK, to fix that - `ControlPanel->Apps&Features` - Find any windows sdk by typing `windows sdk`, - You can grab the latest one and click `modify` - Splash screen and window will pop up. - Select `Change` - Now you see clearly `Debugging symbols` unticked in second order. - Click it and install. Its done, enjoy. ---

Much Obliged. Instructions on Windows 11 are slightly different. As i’m tutorialising it for our business, i’ll share here: Now reading this error, you’d think it needs to be something to do with Windows SDK not being installed. But it turns out Epic haven’t updated the error message in quite a while. The solution is the following: On start bar, go to: Add & Remove Programs → Search the Windows Software Development Kit → Change → Add Debugging Tools for Windows. I had a couple here, so I picked the latest version of WinSDK. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/4/6/4/464757830362f6ee4d60413927a1db9c27cb9f7d.png) All good now.
