Hello, I am trying to package a project in the UE5 early access version for Windows.

Packaging a project works well in UE4 on my pc, but when I try to build a project in UE5 I get the following message:

“The SDK for Windows is not installed properly, which is needed to generate data. Check the SDK section of the Launch On menu in the main toolbar to update SDK.”

I have never had an error like this before, and generally work in Blueprint. Where do I find this ‘Launch On’ menu to rectify the situation?

Thank you for the assistance.

Download this and restart your program. Worked like a charm for me! [Windows SDK - Windows app development](https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk/)
