OK, now that we know you are using 4.8.7 in your IDE, we can be sure
that something is wrong with your environment if you are getting
error messages related to the .IMP files you quoted. They don't
exist in 4.8.7.

(For the record, in versions of IBO prior to 4.x, the source code
units used to be partitioned out into .INT (interface), .PBL
(published) and .IMP (implementation) sections that were consolidated
at compile-time with includes. Now, only a handful of the forms
units remain in this format.)

Implementation sections do have a uses clause but, regardless, the
IBO units already have any uses clauses for VCL units they need. The
variants entry will be needed in your own units, though.

I think your best plan would be to totally uninstall IBO 4.8.7 from
your system and start again with a totally clean install. After
running the uninstall using Add/Remove programs, go around the
system32 and $DELPHI\Projects directories delete any IBO4--
files. Delete the IBO4 directory and recreate it empty. Check in
your Registry whether you have some artifact there from IBO3 that is
pointing the Delphi 7 compiler to the old IBO3 paths...etc.

Then, when you re-run the installer, make certain that you have ONLY
Delphi 7 checked on the selection list that appears prior to the
compile. (If you want to install IBO4.8 in Delphi 5 later, you
can...just don't let the installer try to do both at once!!)

Once you have a clean install, you will *still* have some remaining
issues trying to open a Delphi 5 project in Delphi 7. Pay attention
to the messages that appear the first time you try to do that.

Also, if you installed Delphi 7 from an original distribution CD,
make sure you get updates 1 and 2 from the Codegear site. The Build
No. (on your Help..About dialog) should be 8.1.
