I installed a shared Office program, but the program can't be found.
The Microsoft Office program or component might not be installed, might have been removed, or might be missing some necessary files.
If you installed your Office program as part of Microsoft Office, click Microsoft Office in the Currently installed programs box, and then click the Change button.
If you installed your Office program individually, click the name of your program in the Currently installed programs box, and then click the Change button.
