Windows 10: After 365 update, file explorer doesn't recognize .XLSX as an MS excel file type

Hiya,

I hope someone can point me in the right direction.


I recently installed Office 365 on my laptop upgrading from office 2013.

An application I use a lot, Dymo label print v8, won't import .xlsx data files since the upgrade. The closest I have gotten to finding a reason for this, is that in the file explorer pop up, .xlxs files are no longer listed behind MS excel file types. Does anyone know where to correct these file groupings?

I added a before and after office 365 picture below. I've checked with others who have gone through this update, and they all have this issue.

Thanks a lot in advance!

Troubleshooting:

restart

Reinstalling dymo label printer

Installing new version of Dymo label print Dymo connect

Checking file type associations in regedit



Before office 365 installation:




import window with Office 365 installed.

Hello Donald,

.XLSX is a file extension for an open XML spreadsheet used by Microsoft Excel. For us to better assist you, we'd like to know the following:

• Confirm which build is currently installed on your device. To check, follow the steps below:

• Press Windows key + R, then type in winver.
• Click OK.

• Is Microsoft Excel installed on your computer? If yes, which version of Microsoft Excel are you using?
• Are you getting any error messages when opening the .xlsx files?
• Did you create the said file or was it downloaded from a certain source?

We look forward to your response.

Regards.

 

How to make Excel 2016 the default app to open xls and xlsx data files

You are supposed to double click on the entry for .xls in control Panel > Set Associations and in the window that opens choose "More Apps" then in the file explorer window that opens up browse to the Excel executable and select it.

So launch Excel and leave it running. Start Task Manager [Ctrl+Shift+Esc]

In task manager processes tab scroll to excel.exe and right click on it. Choose "open file location" from the list and in the window that opens locate excel.exe and note the folder path. Use that path to browse to the executable in the step above that mentions browsing to the executable.
