Hi, Cindy Zocchi
Welcome to the Microsoft Community.
Thank you for your feedback. I understand that you are experiencing issues with visio usage. For the issue you are inquiring about, visio cannot be upgraded. Currently, if you can download and install it from the old link, then you are able to use the old version. However, Microsoft no longer provides support for older versions and we recommend that you purchase the latest version.
I look forward to your feedback.
Best Regards,
Aaron| Microsoft Community Support Specialist
