Couldn't load assembly reference

Anonymous — Wed, 21 Aug 2019 20:39:00 GMT

Hi All,

I am getting the below error while executing the code stage,

Internal : Could not execute code stage because exception thrown by code stage: Could not load file or assembly 'Google.Apis.Auth, Version=1.21.0.0, Culture=neutral, PublicKeyToken=a7d26565bac4d604' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

However, I referred the same dll version in the initialize page.

CAUSE: Google.Apis.Gax.Grpc.dll has a dependancy with Google.Apis.Auth, Version >= 1.35.1.0 and Grpc.Auth has a dependancy with Google.Apis.Auth, Version >= 1.21.1.0... I placed the Google.Apis.Auth, Version >= 1.35.1.0 in the program file folder and referred it in the initialize page. Having said that I guess Grpc.Auth cannot load the latest version and it requires 1.21.0.0

How to resolve this issue? Please help me.

Try moving the dll to BP folder in Program files and then reference it.

Does the DLL have other DLL dependencies? If so, have you tried including those dependencies when trying to move it into the Blue Prism installation directory?

It does have the dependency. Based on the dependencies error in BP I am adding the dll(version specific). But still it is throwing the error again and again for certain dlls alone! I keep downgrading the dll version for few components based on the BP exception but still no luck.
