McAfee Data Backup has specific system requirements for normal operations. These are as follows:
- A storage device for your backup files
- Sufficient available space to write the backup data
- Microsofts .Net 1.1 must be installed and working.
If you click on Yes in the pop up it will help you to install Microsofts .Net 1.1 or you could even perform a windows update in your computer to install the same.
Your response appears to have been cut and pasted out of the McAfee Help screens.
If backup only works with .Net v1.1, then McAfee needs to change with newer versions of .NET.
Your answer solves nothing, but thanks anyway.
