In an extra environment I had installed version 2.1.70 of the Center of Excellence Starter Kit Core Components. Today I though about installing the current version. So I went to https://docs.microsoft.com/en-us/power-platform/guidance/coe/setup-core-components and called the aka.ms/CeoStarterKitDownload Link. Extracting the downloaded zip I got multiple files and inside the file CenterofExcellenceCoreComponents_3_19_managed.zip as current Core Components package. As described in the web, I had only to import the new package into my environment and thats it. OK, I´ll give this a try. I went to make.powerapps.com – selected the right environment – imported the package – and bum, error!
The error code is 80040216 – the corresponding help page was not a good help (https://support.microsoft.com/en-us/topic/unexpected-error-80040216-when-importing-solution-in-dynamics-365-2c9537d8-7da1-186e-dc1e-c273e3f5b104). I search for the named connection reference and it exists in the environmelt.
I now startet my research and this were the good links helping me to find the solution:
First I found I should try to install version 3.13 but I got the same error. Than it was mentioned to install version 2.77, but to use the classic solution view, to click Import and to choose „Overwrite customization (not recommended) – see https://github.com/microsoft/coe-starter-kit/issues/1005#issuecomment-904704682
This installed the version 2.77 AND uninstalled 2.1.70:
As 2.77 was installed, I could install 3.19 directly:
I was asked to update 4 connections:
And after that the import of the new version 3.19 of the Center of Excellence – Core Components was successful.
I hope I could help someone with writing this down! Cheers!
