cannot open previous version visio file in visio 2019

Hi Shashi D Char,

First, my pleasure to assist you.

As per your description, please don’t worry, we can work together to narrow down and resolve the situation.

I understand, when we open a Visio file that was created in an older version of Visio, you might see some problems, as you mentioned, “unable to open the previous version file” may I know did you get any error message? If so, could you please upload a screenshot of error message here for our reference so we can understand your exact scenario and provide our suggestion in a productive manner, perhaps some related screenshots will be helpful.

Also, may I know have you tried to go to Visio > Open > select the old file to open the file to check if the same problem will occur. And if the suggestions above don’t work, we’d suggest you go to Control Panel > Programs > Programs and Features > select Visio > right-click and select Change > Online repair.

I suggest you open the files in old version of Visio client to check if the same problem will occur, if it works fine in old version of Visio, you can try to save it as a .vsdx format to check if the same problem will occur.

If the problem still persists after trying the suggestions above, to better understand your situation, could you provide the information below?

1.Could you provide the Product Information and version of your Visio? You can go to Visio > File > Account and provide the screenshot of Account page contains Product Information panel.

2.Do all old files have the same problem?

I appreciate your understanding and stay safe!!

Best regards
