Office: There’s not enough memory or system resources to start

Symptoms

Error messages when selecting a .docx/.pptx/.xslx file in Windows Explorer preview pane:

  • There’s not enough memory or system resources to start PowerPoint
  • There’s not enough memory or system resources to start Word
  • Excel displays an error message with a red cross icon and no text

Solution

This happens when the 64-bit version of Microsoft Office 2013 or Microsoft Office 2016 is uninstalled and the 32-bit version is reinstalled. This leaves references in the registry for 64-bit Preview Handlers.

To fix these errors and repair the preview pane, run Regedit as administrator and delete these registry keys:

Microsoft Excel previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{00020827-0000-0000-C000-000000000046}

Microsoft PowerPoint previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{65235197-874B-4A07-BDC5-E65EA825B718}

Microsoft Word previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{84F66100-FF7C-4fb4-B0C0-02CD7FB668FE}

Microsoft Visio previewer:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{21E17C2F-AD3A-4b89-841F-09CFE02D16B7}

 

A logoff/logon or reboot is required.
