Hi there,

After having installed Office 2003 on WinXP Pro, I find that 'Trust access
to visual basic project' under Security is greyed out. How do I get this
option back on?

I found a thread in archives where the suggestion was to set AccessVBOM in
the registry to 1, which is something already set as such in my machine's
registry. I couldn't find any other solution in the archives, MS knowledge
base or the wider internet.

Thanks,
Amit
