I've got Quest 5.8 installed on Windows and any attempt to publish a game results in:

Unable to Publish Game

An error occurred: C:\Program Files(x86)\Quest 5\Core\DevMode\tabulator.min.js

Anybody able to help? Even a newly created basic game with one room blows up with this.

Thanks in advance!

See the recent post titled "Quest 5.8" in this forum, which has a workaround for this problem.

But not for upload problem yet, I am afraid.

Thank you so much!

Try now.

Still not working......

I tried to post and it said "Failed to load file"

And my file is .Quest so i dont know what to do...
