Microsoft updates won't install on my mac

What did Microsoft suggest?

Ask in their Office:Mac forums here:

Office for Mac

Everyone there is a Mac user AND an Office user, something you can't say about Apple's forums. You will get the fastest help there and I think you will find the contributors more than helpful.

Typically I’ve seen this on three specific occasions:

1. When a program is moved from its expected location. Microsoft dumps all the Office programs into the Applications folder. If you move them somewhere else the updater can’t find it. Move the programs back into the Applications folder if this is the case.
2. The user has in some way modified the application’s package or the application is damaged. Some people try to save hard drive space by removing things from programs either manually or using ‘cleaning’ programs. The updater sometimes expects to find certain files and quits if they aren’t found. Reinstall the programs to fix this.
3. The user’s hard drive directory is damaged. Boot into the recovery partition, run Disk Utility and try to repair the hard drive. If this doesn’t work….probably reinstalling the programs will fix it.

Same here, but on my iMac El Capitan OS. I haven't figured it out yet. You're the only one besides me now that have commented about this in any forum.
