Run-time error 429, ActiveX component can't create object, automate MS Word application, CreateObject("Word.Application")

Question

I'm running into the following error when executing the following line from VBA (Access):

Set wd = CreateObject("Word.Application")

I found the following link, but did not find it useful: http://support.microsoft.com/kb/828550

Things I've Tried

---

• Repair installation of Office from Control Panel > Programs and Features
• Uninstall MS Word, re-install
• Tried Dim wd As Object instead of Dim wd as Word.Application
• Manually run Word.
• Run winword.exe /RegServer in Administrator command prompt. Did not run silently, merely opened Word.
• Examine the LocalServer32 key under the CLSID {000209FF-0000-0000-C000-000000000046}. Initially was missing. After re-install Word, the CLDID was there but LocalServer32 key is missing.
• Run winword.exe /automation. Merely starts Word.
• Run winword.exe as Administrator.
• Run access.exe as Administrator.

Examine the LocalServer32 key under the CLSID {000209FF-0000-0000-C000-000000000046}. Initially was missing. After re-install Word, the CLDID was there but LocalServer32 key is missing

So Word is unable to register properly because you have a system issue.
As that you've tried most or all of the reasonable steps, your next step is to reinstall Windows.

Or you could try manually registering it by duplicating all the relevant keys from a different machine. But that probably wouldn't solve the problem.

Super User might be a better place to ask about installation and Windows registry issues.
