This problem is caused by inadvertently overriding the default Windows settings for file downloads from the web. This will NOT be a problem if you are using the current MS Edge, as it always prompts users to Open or Save downloaded files.
If you do not wish to update your browser, please read on.
To prevent MS Excel from automatically opening and restore the default Windows setting for downloading files from the web:
- Download the following registry settings text file and save to your desktop:
Click here to download csvprompt.reg
If clicking the link above does not prompt to save the file, then right-click on the link and choose "Save Link As..."
For best results, save the file on your Windows desktop
- Right-click on the csvprompt.reg text file that you just saved to your desktop and select Merge.
Windows will change your registry settings back to the default which pops up a file download box whenever you download an Excel or CSV file from the web.
- Reboot your computer.
