August Release - Data Driven Subscription - Failed to load expression host assembly

[bulone84]

Hi,

I randomly get the following error while running a data driven subscription:

Error: Failed to load expression host assembly. Details: Could not load file or assembly 'Microsoft.ReportingServices.ProcessingObjectModel, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's

Sometimes the subscription works fine, on other occasions it will throw this error, without changing anything to the configurations.
