Cireson Self Service portal not working after hotfix 5.0.5

After upgrading a Cireson Self Service portal to hotfix 5.0.5 the site did not start as expected. So I logged in on the server and opened the the site to review the error there.

It said

Could not load file or assembly 'LicenseManagement.Client, Version=1.0.5882.21425, Culture=neutral, PublicKeyToken=98ba2176e2a9efbc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Turns out that the changes to the Cireson licensing has made some changes that requires a newer version of the LicenseManagement.Client.dll different from the version I had (1.0.0.8). This file is located under C:\inetpub\CiresonPortal\bin\LicenseManagement.Client.dll

I contacted Cireson support and they came with the solution quickly enough.

Download the updated installer from https://support.cireson.com/software/#/ reinstall and apply the hotfix again.

Seems there still is an issue with some NavigationNodes disappearing when you do a new install. So be sure to insert those again after your have re-installed to 5.0.1. and applying hotfix 5.0.5

My upgrade path before this hotfix was 5.0.0 > 5.0.2  > 5.0.5.
I think the dll was updated in 5.0.1, since that was the version it reported after a reinstall.
