"The Parameter is incorrect" error message

[mscertified]

Did not quite know where to post this...

One of my users is getting a "The Parameter is incorrect" error message upon
opening his database. This is double-clicking on the MDB file. He claims if
he opens Access and chooses the MDB that way, it opens ok.

I've played with it and cannot reproduce the problem. There is no code in
the database that puts out the message. The database is an unsplit MDB and is
used by multiple people simultaneously. Could this be the cause?
Any ideas?

Sounds like the actual "Open With" options are incorrect - do other people
have the same error message, or just this one person?

Also, it's a very very VERY bad idea to have a single unsplit database
shared by multiple users simultaneously... That is a recipe for disaster.

It turns out the message was issued before Access opened the database. I did
not design the database and have no control overits setup or design. I simply
provide Access support to the users.
