Please see the following instructions for a fix that should resolve your issue with the MSi Adobe Courseware. A temporary folder needs to be writable by our application inside each user’s “Roaming” folder. An empty folder named “msi” needs to be created.
Please note that in our recent testing we have found that the fix does not require an administrative account. This is a one-time per user fix that should resolve the issue.
