I've been stuck on this for a few days now and would hugely appreciate any help. I successfully uploaded my build to the beta release channel, accepted the email invitation, and downloaded my test app. When I try to play, though, I get this error even though the file structure in the build is clearly done as specified. One thing I noticed is that the "Date modified" field of the .exe file still shows 7/7/17, even though I am building and saving new executables (as shown by the "Date modified" field of the data folder).
I don't understand how I pass the check for the Data folder upon uploading, but somehow get the error that I don't have a Data folder after installation...
I'm using this command to upload via the Oculus CLI (I've also tried uploading via the website uploader):
ovr-platform-util upload-rift-build -a [app ID] -s [key] -d "C:\Imaginarium Build\Imaginarium\" -l "imaginarium.exe"
-n "First upload." -v 1.05 -c Beta
I've also made sure to save the build in a new folder every time and delete old development copies of the game.
