Error 3221 - The Application does not support the tech version of the course.
You may have an older version of the language level CDs.
This error can be caused when you are installing an older language level disk to a newer Rosetta Stone Application.
You can identify the language level disk version on the front of the CD.
For example, you will see something like 7.3.0r6.
If you have any language level disks that are lower than version 7.5.2, then please contact Rosetta Stone Support
for further assistance.
