The crash of Microsoft Office you just experienced could likely be avoided by installing a Microsoft Office update, KB2837581. Microsoft released this update on July 8, 2014, and it is usually installed automatically. If it is missing on your computer, Office updates may have been deactivated by you or your company's IT.
You can download the update from Microsoft by going to KB2837581. You may need your IT's support to install it. Note that there are two different download links for the 32-bit and 64-bit versions of Office 2010. Unfortunately, Microsoft's "Am I running 32-bit or 64-bit Office?" link on the KB2837581 page does not work anymore. You can find this information by clicking on PowerPoint → File → Help. On the right, note the version information under About Microsoft PowerPoint: It shows (32-bit) or (64-bit).
