InterestNet FAQs

InterestNet 7 Changes

What is new in release 7?

InterestNet 7 is not an update to previous systems, but a completely rewritten system using state of the art development tools and programming architecture to make it compatible with current and future releases of Windows.

InterestNet 7 has also undergone a major redesign effort to make system navigation more user-friendly.

Users should view the “Whats New in InterestNet7” video on our website before installing version 7, this video is approximately five minutes long, and will give users a good idea of what to expect when they first open InterestNet 7. 

Can the user have both systems installed?

Yes, we actually suggest that the user keep both systems (InterestNet 7 and 6.90) installed for a period of time, until they become completely familiar with the new system.  DMI will continue to support release 6.90 for a period of time, to allow clients time to phase in the new system.

Will my previous data files (“.DMI”) be usable by InterestNet 7?

Yes, all previous 6.XX versions of InterestNet data files will work in the new system.  Please note, however, that these files will be converted to release 7 compatible version of the data file and will not be able to be opened in any pre-7.0 system after that.  As a safety precaution, the system will automatically save a copy of the version of the file prior to the conversion as a . DMIBKUP file, in the same location as the file being converted.  Thus an archive of the previous versions of all files converted will automatically be present unless the user elects to delete them.
