Using MS Access/MS Access Problem

Question
QUESTION: Hi Scott
This is probably outside your normal realm but I thought I would ask you anyway.

I am running Win 7 with Office Professional 2010 installed.

Everything was running well; until today hat is.

When I went to open my database this morning I got the error message "Cannot open the Microsoft Access database engine workgroup information file". I get the same message if I try to create a new database file.

I uninstalled Office Professional and re-installed it in the hope that that might solve the problem, however it still persists.

Have you any ideas on this? Perhaps you may have encountered this problem in the past?

Regards
John

ANSWER: The message indicates that you are running an mdb/mde app that has ULS set up using an mdw file. And that's what can't be opened. You need to check the location of the mdw.

If that's not the issue let me know ad I'll see what else I can suggest.

Hope this helps,

QUESTION: Scott
Thanks for your reply.
You mention mdb/mde app. My files are accdb files. Does this make a difference?
I assume that ULS is "Universal Logging System" and that the mdw file you refer to is of the format xxx.mdw.
I have attempted to locate an mdw file on my computer but all me efforts have been to no avail.
How do I go about locating the mdw?
Thanks
John

Answer
Actually it stands for User Level Security. This feature was deprecated with Access 2007, so it does not work with accdb files. However, if you upgraded from an earlier version than 2007, you might still have an mdw (the workgroup information file) still on your system. It has probably become corrupted and needs to be replaced. I would search your system for system.mdw. See what folders you have copies in. You may have to move them from where they are to somewhere else. Access should then recreate the file. If that doesn't work. Let me know.

Hope this helps,
