v3 to v4 data upgrade - Hostpolicy.dll missing

[BelloWeather]

Hi all

Trying to upgrade from v3 to v4 on Windows. Have upgraded dotnet to 8 as requested. Trying to run the migration tool to upgrade data from v3 to v4 and getting this response:
A fatal error was encountered. The library 'hostpolicy.dll' was not found in c://program files/dotnet
The program failed to run as a self contained app

It them goes on to say that it ran as a self contained app as a json file was missing, but then failed because the hostpolicy was missing.

Computer restarted, updated...tried everything but can't get beyond this part of the upgrade. Am I the only one? Did a search here and couldn't see the same problem for anyone else. Advice appreciated

In the MXDiags folder there should be a file that starts Migratexxxxxxxxxxxxx.txt could you post that as it might give a clue as to what is going on.

In a command window what does "dotnet --info" give you?

I've got this problem too. Here's the error I'm seeing:

Code: Select all

A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in 'C:\Program Files\dotnet\'.
Failed to run as a self-contained app.
  - The application was run as a self-contained app because 'C:\CumulusMX\MigrateData3to4.runtimeconfig.json' was not found.
  - If this should be a framework-dependent app, add the 'C:\CumulusMX\MigrateData3to4.runtimeconfig.json' file and specify the appropriate framework.

There's no Migratexxxxxxxx.txt file in my MXdiags folder.

dotnet --info says I'm on version 8.0.11

Code: Select all

Host:
  Version:      8.0.11
  Architecture: x64
  Commit:       9cb3b725e3

.NET SDKs installed:

.NET runtimes installed:
  Microsoft.NETCore.App 8.0.11 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

Any help with this would be great - thanks heaps

Is the runtimeconfig.json file mentioned in the error message present?

[nickb]

No, I can't see MigrateData3to4.runtimeconfig.json which is in the error.

The only runtimeconfig.json file is called CumulusMX.runtimeconfig.json.

I am exactly the same as you, I wanted to install the new version 4 from version 3, but when I run MigrateData I don't get any response, not even what error I have.

[HansR]

@Mark: should MigrateData3to4 have been recompiled (like the other auxiliary programs) with version 4.3?

[mcrossley]

I don't think so, but I'll check. The missing JSON doesn't sound right though

[mcrossley]

Please add the attached files to your Cumulus MX folder and try again.

[Juan Maria Vilaro]

Good afternoon, files downloaded, and I have finally been able to migrate CumulusMX-V4, everything seems to be working.
Yesterday I was on the forum all day, even with Mr.Hans, and I didn't notice until this morning that some files were missing.
Solved by me for now.
Thanks

[HansR]

OK. Great teamwork

[nickb]

Brilliant, yes confirmed all working for me now. Thanks for everyone's help and quick replies on this

[BelloWeather]

A late reply to say many thanks to everyone for their work on this - going through the process of updating now using the new files
