The System Requirements Check was unable to write to the Documents folder ("My Documents" in Windows 7/8/10) of the currently logged in user.
In-Application tests need to store the assignment document somewhere and this is currently done in the Documents folder. If this location is not writable then the test will not work. Please check permissions on the Documents folder and try the test again.
If you cannot resolve the issue, you must copy the System Requirements check log and send it to PSI support. See the ATLAS Cloud System Requirements document for information on how to do this.
