The infrastructure of the Visual Studio 2010 Tools for Office Runtime relies on three primary layers:
The requirement is dictated entirely by the , not the bitness of your Windows Operating System. System Environment Scenario Appropriate Runtime Selection
Loads VSTO add-ins and document-level customizations.
A 64-bit Windows operating system can run both 32-bit and 64-bit software. However, a 64-bit Microsoft Office application cannot load a 32-bit runtime component. You must deploy the x64 runtime specifically for machines running the 64-bit version of Office suites like Word, Excel, or Outlook. Component Ecosystem
If an essential enterprise add-in stops appearing in your Office Ribbon entirely, the runtime might be disabled or corrupted.
Therefore, if an end-user is running the 64-bit version of Microsoft Office (a common scenario on modern 64-bit Windows systems with large datasets, as 64-bit Office can handle more memory), they have the x64 version of the VSTO runtime installed on their computer to run any 64-bit VSTO-based add-ins or customizations.
The VSTO 2010 Runtime is often installed automatically by developers during software installation. However, if you are experiencing issues with Office add-ins not loading, you may need to install or repair it. Finding and Installing
As such, you should . If you're using the 32-bit edition of Office (which is the default and still very common), you should install the x86 runtime. Choosing the correct installer is not optional. Furthermore, special consideration must be taken when working with 64-bit native components: your solution must be properly built to target x64, and its registry keys will be stored in a different location within the Windows Registry hive for 64-bit applications, which can be navigated during development.
: For users of older VSTO add-ins, this runtime is mandatory. Modern updates have resolved historical performance issues, such as a 15-20 second delay when closing Office apps. Compatibility
