C# DLL Error - Server 2003

[zeplynne]

I have a C# DLL that targets the 1.1 Framework. This dll
is called by unmanged code (ASP, windows apps, etc...).
When the dll is on almost any OS it works fine, except
when it is on Server 2003.

The error I receive is:

error '80131418'
Execution permission cannot be acquired.

This dll was originally created with 1.0 then modified to
target 1.1. It has been in production over a year and a
half with no complications.

Has anybody seen this error before? Not much about how to
resolve on the Internet, actually I couldn't find anything
that helped on softy's site. Can anybody let me know what
may be the cause of the error stated above.

Thanks.

*Uninstalling MDAC security or IE sp1 updates does not
always solve the problem.

OK. Here's the fix.

Security update (828750) which replaces (822925). But the
kicker, it doesn't work if you have previously installed
(822925). Removed (822925), registered dll's and it
worked.

Spoke to Microsoft, they said that 828750 should fix the
problem regardless, now they need to know that removing a
patch to make a patch work is unacceptable.
