This issue has been solved. See solution.

Hello community
yesterday I installed the servicedesk solution (V 7.1 SP2), with his Workflow solution too

Now, I tried to modify a project (SD.EmailMonitor) but in the moment that the project is loading appears this error:

System.MissingMethodException: Method not found: 'Int32 LogicBase.Core.ProjectData.get_CreatedWithVersion()'.
   at LogicBase.Tool.ProjectLoading.ProjectLoader.CheckBuildNumber()
   at LogicBase.Tool.ProjectLoading.ProjectLoader.LoadProject()
   at LogicBase.Tool.Program.LaunchTool(String[] args)
   at LogicBase.Tool.ToolInitilizationHelper.Main(String[] args)

This same error appears when I try open all projects.

What's wrong?

It looks like your LogicBase.Core DLL is out of date... can you go to C:\windows\assembly, find Logicbase.Core, and read the version? Workflow 7.1 SP2 initial release should be 7.1.1460.

If that version isn't there, you should just manually upgrade WF to this version.

Thanks, the problem was that in this server was installed SD 7.5, it was uninstalled and then was installed SD7.1 SP2. I uninstalled the dlls V7.5 but, now don't open the workflow designer. I want repair this installation but now the SD installer appears this error too

When you uninstall Workflow to downgrade, it's also a good idea to remove any remnants of our GACced DLLs from the GAC as well (if they exist). The GAC is shown when you navigate to C:\Windows\assembly in Windows Explorer. The DLLs to remove are as follows:

LogicBase.Core (and associated resources)

LogicBase.Framework (and associated resources)


Symantec.SymQ (and associated resources)


If these DLLs still exist at C:\Windows\Assembly after uninstall, stripe them, and then right click and select Uninstall.

If you've uninstalled and you can't remove them because they're "in use", you can force them to be uninstalled by deleting the appropriate folders in DOS:









After you've uninstalled from the GAC (or deleting the folders above, if you had to), delete EVERYTHING that exists at the original install location. Also remove your ProcessManager database (if you're downgrading). Then try running the installer again.

thanks reecardo.
aditionally to dll's that you posted, had some dll's "Police.Symantec.SymQ", "Police.Symantec.SymQ.resources" and "Police.LogicBase.Framework.DatabaseDrivers".

I deleted these dll's and the error has solved
