Oct 11, 2019 Want to update to macOS Catalina but can't justify losing access to all the outdated 32-bit apps I rely on (looking at you Microsoft Word for Mac 2011). Apr 16, 2018 Describes an issue that occurs when you double-click or drag a file from an earlier version of Word for Mac onto a Word 2008 for Mac program icon. In this scenario, the file doesn't open. If the problem still occurs, quit PowerPoint, and restore the file to its original location. Then, go to the next step. If the problem seems to be resolved, you can move the com.microsoft.powerpoint.plist file to the trash. Quit all Microsoft Office for Mac applications. On the Go menu, click Home. Open Library.

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

To complete the connection, the router must perform the port forwarding.Routers can send traffic that arrives on a specific port to a specific computer. Once they’ve been configured to send VNC traffic to a particular computer, all incoming VNC connection requests are directed to that computer.If you’re going to use VNC across the internet, it’s advisable to use a nonstandard port. 
The remote router must then be configured to forward connection requests for port 43025—or whichever port you choose—to the Ubuntu computer on port 5900.RELATED:That’s like ringing the hotel and asking to speak to the geek in room 43025. By default, the remote Ubuntu computer listens for VNC connection requests on TCP/IP port 5900.This is a well-defined convention, but we verified it anyway by analyzing some network traffic:We can mask that detail from the outside world by using a nonstandard port, like 43025. The operator knows the geek is really in room 5900 and connects your call.

Step 4: Create a new user account
Sometimes, a specific user's information may become corrupted, and this may prevent installation, startup, or use of some applications. To determine whether this is the case, you can log on to the computer by using a different or new user account, and then test the application.
If the problem no longer occurs, the cause exists within the user's home folder. If you think that the user account was responsible, you can continue to troubleshoot by using the new user account.
