This article specifically covers the error code of 0x8007000d



Cause:  
500.19 - 0x8007000d is usually thrown when there is a problem with .NET (Core) or a .NET Module
Each version of IdP has a requirement for .NET Core, or .NET in later versions, to be installed on the IdP Servers, without it installed, there will be problems seen with IdP

The 0x8007000d error has been caused in the past by .NET (Core) not being installed but the much more common reason this error is seen is due to an earlier version of .NET (Core) being uninstalled after a newer version has been installed.

When uninstalling a version of .NET (Core), it can uninstall parts of .NET (Core) which other versions being left on the Server require to run correctly.
This can leave the the Server in a state which looks as though it is setup correctly but actually has problems in the background.


Resolution:  
See the following for the compatible versions of .NET (Core) for each version of IdP - https://docs.secureauth.com/2404/en/secureauth-compatibility-guide.html#required--net-versions

If a compatible version of .NET (Core) is already installed on the system, the first recommendation is to run a 'Repair' against each part of that version via 'Add/Remove Programs'



Run a repair against each .NET (Core) module and once complete, test Identity Platform again to see if it has rectified the error(s)

If an incompatible version of .NET (Core) is installed, it is recommended to uninstall all parts of that version of .NET (Core), then install a compatible version after
It is important to install the compatible version AFTER uninstalling the incompatible version
