This means that the Firefox thinapp package is not available to the Windows client machine. We will need logs from your Windows client machine to know why. This is how you can collect your logs. Open the Workspace app in your Windows System Tray. Click on Options. Click on Collect diagnostic information. It will generate a zip file and put it on your desktop. Send us that zip file.
Looking at the logs, there is no evidence that you logged in from the Workspace Windows client. Please login from the Windows client using the same credentials as what you login to Workspace on web browser and try again.
