The ‘Dose’ tab is absent, which is a concern.
If the ‘Dose’ tab does not appear on the Excel ribbon, some files may be missing, and you should attempt the following fixes individually:
1- Re-open Excel and check if it works after downloading and installing Microsoft.NET Framework 4.5 or the newest versions from the link:
Microsoft .NET Framework 4.5
2- If the above doesn’t work, open Excel and go to File –> Options –> Advanced. Add-ons –> ‘Manage’ at the bottom —> ‘COM Add-ins’ –> ‘Go…’ –> ‘Dose for Excel’ is checked. Check to see if it works now.
