OfficeDrawIo is a Microsoft Office add-in that allows embedding and inline editing of Draw.io diagrams into Word and PowerPoint documents. Users without the add-in are able to view the diagrams but not edit them.

Check your installed version (bitness) of Microsoft Office before picking the right installer. x86 is for 32-bit Office and x64 is for 64-bit office.

Note: Version 2 is NOT backwards compatible with version 1. If you have any documents using version 1 of OfficeDrawIo, please extract the document images first (extracted as DrawIo editable vector png files) using the Export add-in option in Word before installing the new version.

• Windows OS with .NET Framework 4.6 or better.
• Office 2017 or better (may work in earlier versions but not tested).
• Draw.io Desktop.

1. The add-in does not show up in the Word or PowerPoint ribbon.
   • Make sure you installed the correct installer for your Office Version. If in doubt you can install both.
   • Right click onto the PowerPoint ribbon area and select Customize the Ribbon... -> Add-ins -> Manage: COM Add-ins -> Go..., make sure that the OfficeDrawIoPpt or OfficeDrawIoWord add-in in the Add-ins available list is checked.
2. When I try to edit a diagram I receive the error "Failed to start Draw.io Desktop application for file ... System.ComponentModel.Win32Exception (0x80004005): Access is denied"
   • Check if your antivirus or Microsoft Defender has a special configured policy blocking Office applications from creating child processes, e.g. by looking into your Microsoft Defender protection history. If so, to get around this, you will need to create an exclusion policy for path "C:\Program Files\draw.io\draw.io.exe".
3. Draw.io picture randomly dissapears from PowerPoint on edit.
   • Please disable the autosave feature in the draw.io application.
