I did exactly as written here: How to fix the "Internal server error: Could not load... / ActiveDBSoft (activequerybuilder.com)

Still cannot deploy my application though. I works fine on my development computer, but on my deployment server it keeps on stumbling over this message:

Could not load file or assembly Oracle.ManagedDataAccess, Version=4.122.19.1, Culture=neutral, PublicKeyToken=89b483f429c47342 or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).

It's generated at setting a connection to the metadataprovider:

TryCast(metadataProvider, OracleNativeMetadataProvider).Connection = con

I really hope you have a working solution for this...
