query cannot be executed

Hello. When I attempt to query a table I receive the
error from the SQL Enterprise Manager "The query cannot
be executed because some files are either missing or not
registered. Run setup again to make sure the required
files are regestered." This is the path that I use:
Enterprise Manager - sql server to attach to - select
database - select table - select to query all rows. Then
it looks like it is starting then the I get the error.
Please help!
I also have uninstalled & reinstalled the MDAC. Did not
correct it.
This is strange because it worked Friday & come back
Monday & it doesn't work?
I solved this problem by removing the registry key
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Set up\ExceptionComponents
and reinstalling MDAC 2.8.
Egon.
