What does "don't run" actually mean? In what way(s) do they fail? Are
these two applications consistent in the way they fail?

In your DPR, have you taken explicit care of the creation order of forms
and datamodules? That is, taking care that the DM is created before any
forms that contain controls that use it, etc.

1. Are you sure that IBO is looking for and loading the correct client
library?

2 What about hard-coded database paths that might be lurking around in
statement objects? (quite a common legacy in converted projects!)

3. In case the IBO element is coincidental, are you sure that the
Microsoft C and C++ runtimes are installed on the problem servers?
