After installing Office, opening Encata Results in Error 1..

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

Can anyone help with the following problem associated with AutoRourte &
Encata contained within Works Suite 2005 on hard drive. Problem appears to
have developed since I installed "Microsoft Office about a month ago.
On opening either from "recent" or "all programs", I'm advised that "feature
is not on disk" & asked to insert disk. If cancled, recieve error 1706 - "no
valid source ...". Clicking OK results in Fatal Error.
On opening from Explorer, programme starts but then I'm similarly advised
that "feature is not on disk" & asked to insert disk. Again if cancled,
recieve error 1706 - "no valid source ...". Clicking OK causes loop around
"feature is not on disk" & "error 1706". On third loop programme runs
normally.
Any advice as to solving this?
