I am tryin to install the App "Any Record Hierarchy" (https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000G12hNUAR) from AppExchange on my Sandbox, but i get an error: Problem:
- Unexpected Error The package installation failed. Please provide the following information to the publisher:
Organization Name: .... Organization ID: .... Package: AnyRecordHierarchyv2 Version: 3.0 Error Message: The post install script failed.
What could go wrong? I installed this app yesterday on my dev org and it was working fine.
