I’m packaging a windows file, but I keep getting an ‘UNKNOWN ERROR’. Here’s the output log, thanks in advance!

If you read just a little further up you will see:

UATHelper: Packaging (Windows): Platform Win64 is not a valid platform to build. Check that the SDK is installed properly.

So that would be a good place to start, not sure if this will be the main issue as if you believe the sdk is installed then therr could be a further issue. But a place to start none the less.

So ensure everything is installed correctly for win64 BUT i also see your project mentions VR, are you building to the correct platform?

Thankyou for the response!
I’ve made sure that the sdk is installed properly, even still my quest 2 does not show up in the device manager. I’m trying to package the project for windows so I can use my computer’s processing power to run my quest. I’ve done this before on a different computer before so I know it can be done. But while setting this up in my personal computer I’m probably missing something because of which the package always fails.
