COM, COM+ & ActiveX Support & Maintenance Australia

Overview

COM, COM+ and ActiveX are the binary component model underneath most Windows business software from the 1990s and 2000s. They surface today as registration errors after a server rebuild, COM+ applications that fail silently, and ActiveX controls that modern browsers simply refuse to run.

What we handle

Diagnosing and resolving registration, threading-model and marshalling errors
Rebuilding COM+ application configurations after server migrations
Recovering functionality from compiled DLLs when no source code survives
Bridging COM components into .NET via Interop for modern callers
Planning safe replacement of ActiveX-dependent browser features

What this usually looks like

Signs your COM, COM+ & ActiveX system needs a specialist, not a generalist.

“Class not registered” errors after a server rebuild or migration
COM+ applications failing silently with no clear log trail
ActiveX controls blocked outright by current browser security
32-bit versus 64-bit registration conflicts on newer servers
Components that exist only as a compiled DLL, with no surviving source

The bridge

Old and new, working together

Wrap a legacy COM+ component in a .NET class library so modern applications can call it safely without understanding its internals.
