Peter,

I tried to upgrade from 5.3.8 to 6.0.1 and it failed. I rolled back from the latest backup. Here are a few lines where the install failed:

Info Loading Uninstall.SqlDataProvider
Info File Uninstall.SqlDataProvider read successfully
Info Loading Version History.Txt
Info File Version History.Txt read successfully
EndJob Reading files done.

Failure ExceptionSystem.Exception: Dnn load failed, aborting at DotNetNuke.Modules.Admin.ResourceInstaller.PaDnnLoaderFactory.GetDnnAdapter() at DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.Install()

Should have mentioned that I am running 4.9.5. I am planning on upgrading the DNN instance in the near future but it will be quite an undertaking as I use it for an intranet.

Hi Brian,

DMX 6 won't run on DNN 4. The installer should reject it. The dependency is now 5.2.3. But we recommend you try to go to DNN 6.

Peter
