stdole dll is a Windows system component that contains Primary Interop Assemblies. It is required for working with multiple Microsoft and third-party programs. The installation process is simple and straightforward.

Main purpose

This DLL library offers you standard Primary Interop Assemblies (PIAs) for the office products from Microsoft. It is also used by the Visual Studio integrated development environment. If the original file is missing or corrupted, you can download a fresh copy and replace the source item.

PIAs are collections of types that are deployed and configured as a single unit. An interop assembly, however, includes only definitions of previously specified types.

How to setup

Users are instructed to unpack the contents of the included archive to a subfolder in the main Windows directory. The exact destination depends on the OS edition: SysWOW64 for 64-bit versions and System32 for 32-bit operating systems.

Please note that some apps may require placing the DLL file into their respective main directories. It is strongly recommended to restart the system for the changes to take effect.
