Dear my friends 

i had on-premise dynamics crm v9.0 version 9.0.6 

i update it to 9.0.14 

after update complete , when i want to save my lead it shows me the following error

Assembly content(Microsoft.Dynamics.Sales.Plugins, Version=9.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35) does not match the expected assembly identity (Microsoft.Dynamics.Sales.Plugins, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35).</Message>

the complete log file is attached . 

i copy the older version of this file to the folder and it seems the error solved . but i need to solve it in a right way

    After upgrading to the 26.5 release, still same error. 

    We need to restore the old 9.0.0.0 dll in order to get things working correctly.

    I also miss in my on premise env the role for 365 mobile device user. Can it be this has to do with this plugin/dll mismatch as well?

    Thanks for the tip of restoring the previous v9.0.0.0 of that Microsoft.Dynamics.Sales.Plugins.dll.  That gets me past the error . My error diffrent ı cant give role systemuser. When I replace the dll my error resolved.

    Interesting they say its fixed. I have just tried applying the 9.0.24.8 update (January 2021) and still getting the same old sales.plugin error. Updating the DB as suggested by some here doesn't work. It still complains about the 9.0.1.0 and 9.0.0.0 mismatch

    Only the DLL replacement works which means we still aren't fully updated on prem - we now have a sales plugin from 2018 we have to use instead of one from 2020 - not sure what that means we are missing out on. I had to disable the org in deployment manager to replace the DLL too because it was 'in use' and stopping services didn't help. Bit awkward, but there we go - at least in the about it says 9.0.24.8. @Microsoft please fix or provide a workaround that isn't replacing with old DLL! 0.14 has not sorted the issue.

    We had the same issue after installing 0.21 update and db update didn't help us.

    Copied 9.0.0.0 dll from crm server installation media to CRM server \Program Files\Dynamics 365\Server\bin\assembly resolved the issue. And ofcourse renaming the exising one and reseting iis afterwords.

    MS apparently resolved this issue in update 0.14 as described here.

    Resolved:
    Cause of issue: Old org DB backup from previous CRM Version is restored. Now CRM DB is in old version and CRM itself is in new version and conflict happens.
    Fix: Restore DB and remove and  RE-Import Org.

    Sorry for the delay. What a crazy week.  I just copied the Microsoft.Dynamics.Sales.Plugins.dll from the original Dynamics 365 V9 media that I used to originally install the server.  I renamed the file in C:\Program Files\Dynamics 365\Server\bin\assembly to Microsoft.Dynamics.Sales.Plugins.dll.bak just in case.

    Thanks for the tip of restoring the previous v9.0.0.0 of that Microsoft.Dynamics.Sales.Plugins.dll.  That gets me past the error preventing Opportunity forms from opening for now.  Hopefully, Microsoft will chime in with a better fix.  This happened to me this weekend after updating to 9.0.17.8

    Hi, 

    Is there an update on this? I updated the organization, did an IIS reset but I still get the same error. Can someone help me out?

    Kind regards,

    This does not solve the problem in my case. All imported 8.2 Organizations in my 9.0.15.9 Environment are updated in deployment manager (Version 9.0.15.9, Update: not available) and having all the same issue as described here. Only newly created Organizations don't have this issue. In PluginAssemblyBase Table all Organizations, the working ones and the ones having the issue, have the same records.
