Unable to load Microsoft plug-in on a fresh CRM 9 on-premise organization

(1) ShareShare
ReportReport
Posted on by MateuszBender 216

Is it me, or is CRM 9 very bugged and absolutely not ready for release? The reason I'm asking is because once installed and once I deployed a clean organization, I can't seem to access leads or quotes.

The error is a plain "Unable to load plug-in assembly" - since these appear to be on-retrieve plugins, there's no additional information available on the form. Event Viewer has a bit more:

This is clearly a MS bug as, again, this is basically a fresh CRM 9 install with a fresh organization.

How do I resolve this issue?

    Can you verify the plugin is present

    1. Settings->Customization->Customize the System

    2. Select Plug-in Assembly and locate the plugin Microsoft.Dynamics.LeadManagement.Plugins

    Validate the .NET version supported is installed on your server.

    support.microsoft.com/.../compatibility-with-microsoft-dynamics-crm-2016

    Can you verify your installation has the correct prerequisites and step s followed.

    docs.microsoft.com/.../software-requirements-for-microsoft-dynamics-365-server

    www.microsoft.com/.../details.aspx

    Otherwise try going to the Default Solution and remove the plugin from the Plug-in Assemblies list.

    1. Settings->Customization->Customize the System

    2. Select Plug-in Assembly and locate the plugin Microsoft.Dynamics.LeadManagement.Plugins

    3. Click Delete

    No, the Assembly Microsoft.Dynamics.LeadManagement.Plugins.dll is NOT listed in the plug-in assembly list.

    If you were able to inspect the plugins and steps within the Plugin Registration tool it might be there.

    go to the folder "C:\Program Files\Dynamics 365\Server\bin\assembly" and set Security permission for local group "Users" as "Read and executes". After this restart IIS server (IISReset).

    Thank you so much!  This issue has been driving me NUTS for months, and I wish I would've known this was so simple so solve a while back!  I was getting errors constantly here and there, and I had even submitted an incident for this to Microsoft, and they didn't even come back with a quick answer like this.  I'm going to the forums for now on.  By the way, you don't need to grant "Users" those permissions, necessarily... the only "person" who needs that access is the account that your Dynamics CRM/365 app pool runs under.  I granted that specific account "read and execute" access as suggested, restarted IIS, and no more errors!

    MateuszBender,

    I have felt the same way about Dynamics 365 On-Premise 9.0 since first installing a few months ago.  There are WAY too many ridiculous little bugs that make the system VERY difficult to use, and it seriously seems like they are doing everything they can these days (including leaving ridiculous bugs in the system when released) to try and convince you it's not worth your time to run it on-prem, so you, instead, go to their cloud offering.  This is similar to what they did with Exchange Server years ago, to push everyone to Office 365/Exchange Online... made a product that used to be powerful and fairly-easy to administer incredibly complicated and difficult to setup and administer, and left it riddled with bugs, so it became an absolute nightmare to administer.  Shame on Microsoft for treating their customers this way.  They obviously had to solve these same bugs in their own cloud implementations (presuming they're using the same codebase), so I don't understand why they don't at least pass the bug fixes back to the on-prem versions of their products, too.

    After installing the 0.14 update, the program made an error when displaying Quote "Unable to load plug-in assembly".I noticed that the database had not been updated, so I run Deployment Manager, and after going to the Organizations section, right-clicked on the organization and clicked Update.When the database was updated, the problems were resolved.
