project is 4 parts, 1st upgrade current environment to 2010sp4, then to 2015R2, then to 2018R2, finally to 2019. I have used the same set of addins for all 4 upgrades. Nos issues with the addins I was using until I upgraded to v2019. The 2019 upgrade went great, no issues. When I try to start gp2019, a dialog box is displayed stating An error occurred while loading or initializing an addin. I went to the event log to see what addin was the issue, it appears to be: Microsoft.Dynamics.GP.BusinessIntelligence.BIReportDeploymentGP.dll.
from the event log:
An exception occurred while trying to load or initialize the addin located at BIReportDeploymentGP. Exception Details: System.TypeInitializationException: The type initializer for 'Microsoft.Dexterity.Applications.root' threw an exception. ---> System.InvalidOperationException: Assembly [Application.Dynamics, Version=18.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35] conflicts with the dictionary [Microsoft Dynamics GP, version 18.0.704]. at Microsoft.Dexterity.Bridge.DictionaryRoot.ValidateVersion(Assembly assembly) at Microsoft.Dexterity.Applications.root..cctor() --- End of inner exception stack trace --- at Microsoft.Dexterity.Applications.DynamicsDictionary.SyReportListForm..ctor() at Microsoft.Dexterity.Applications.DynamicsDictionary.SyReportListForm.get_Instance() at Microsoft.Dynamics.GP.BusinessIntelligence.BIReportDeploymentGP.BIReportDeploymentGPAddin.Initialize() at Microsoft.Dexterity.Bridge.AddinManager.LoadAddin(String name, Type type, Boolean checkPlatformAttribute, Int32 currentDexPlatform)
This addin does exist in the addins folder and has been used successfully in three previous upgrades, 2010sp4, 2015Rd, and 2018R2. This is the first time this error has occurred. The system has been rebooted, no help. I have read a ton of articles related to this error related to unable to load or can't find the addin.
