Today, when installing office Visio 2016, click setup, and the following error appears:

The reason for this problem is that your computer has installed 32-bit office before. When you uninstall it, the registry is not cleaned up

Solution:

In the bottom left search box of win10 system, enter “Registry Editor” or “regedit” to enter the registry manager

Go to HKEY in turn_ CLASSES_ Root/installer/products, after expanding products

You will see the registry key values beginning with “00006”. Delete all these key values

Note:

If it is office2013, prompt office 15, find the items beginning with 0005, and delete them all
if it is office2016, prompt office 16, find the items beginning with 0006, and delete them all
