How to resolve
This issue can be related to an update to InSight online Historian performed by AVEVA on Dec December 9, 2019. To fix this, a registry change is required on the Dream Report machine.
You should run this registry update file on your Dream Report machines (64-bit operating systems). Since this will make a change to the Windows registry, we recommend they first make a backup of the registry. The file is available on our DropBox site:

This is the registry change contained in the update file:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
