Possible cause for issue: “Error code -2147221164 class not registered”

By | March 14, 2023

In Sage 300 ERP, user might come across some complicated error messages while opening screens (UI). In this blog we will discuss about one of the common errors while opening the customized screen or a third-party module screen.

Many times, when standard Sage 300 screen is customized by the third party by adding some additional functionality in it. User might come across some issue while opening the customized screen. Refer below screenshot, where standard sage 300 OE entry screen is customized in some custom module where additional functionality is added into it. When user tries to open this customized OE order entry screen user get an error “Error code: -2147221164 Class not registered”.

However, the error description is quite simple to understand, that the control/ screen or rather OCX is not registered properly. And it needs to be register properly. But, sometimes screen might already have been got register properly, Or it can be registered with REGACC command.

But sometimes this command or registering individual OCX manually will also not work as the possible cause for the error might be some DLL to which it is referring to is not getting registered properly.

So below solution might help to resolve the scenario:

  • The DLL used for a project needs to be rechecked it has been taken from a proper path and it is validated.
  • Sometimes we had taken a DLL proper but then also we face an issue because it is not properly built.
  • It might require rebuild to the .NET assembly i.e. DLL which is used for a customized project.
  • Then need to create codebase “.tlb” file from the same and need to register that “.DLL” at proper location.
  • Reopen the sage and now you will be able to open a customized screen without error.

Note: Sometimes this may require remaking of OCX with the latest references as well. But if there is no changes in the assembly and only its registration is a concern then it will definitely help.
