This is due to internal changes between 4.0 and pre4.0 versions. This along with other technical considerations should be noted if choosing to work in both versions.


Though not prevented, there are some known considerations if you will be working in previous versions and 4.0. Those that are notable are listed below.


  • If Hanger Configurations are edited in a pre4.0 version, various settings will be reset to default when returning to 4.0
    • "ANY" Hanger Configuration Rules will not be honored in pre4.0 versions resulting in a "could not find an applicable rule notice".
    • From Branch/Tap value will be reset ( inheriting from end value )
    • Use half perimeter and Highlight unresolved will be restored to false in the project.
  • If Spool Settings are edited in a pre4.0 version, Renumber spools when created/modified will be restored to false when returning to 4.0
  • User will lose hotkeys for family browser when a pre 4.0 version is used.
  • Users will loose loose assigned Network path and hotkeys for Element Filter
  • Pre-4.0 versions will not receive new notifications.
  • EULA acceptances will be reset resulting in user being asked to accept again

eVolve uses a presentation tool called DevExpress to aid in development, which is also commonly used by other softwares. We ensure our version is always the most current available to provide you with the best experience possible. However, other add-ins that are installed may still use older versions which will cause conflicts.

To Fix

  • Remove the problem add-in
  • Contact the add-in developer and ask them to update Dev Express.
