What is the exact window that pop up is it the windows installer screen or
for BCM ?Go to start > run > Outlook /safe and see if the issue occurs.Also
if it a windows installer screen go to start > run > msiexec /unregister and
then msiexec /regserver .Go to services.msc and check the status of
MSSQL$MICROSOFTBCM (for version 1) or MSSQL$MICROSOFTSMLBIZ (for version 2)
and make sure it is set to started.Hope this help.
