QOCIDriver: unable to create environment

I’m trying to move my application to 64 bits. That’s why I build qt4.7.3 with the VS2010 ×64-compiler. I’ve used -qt-sql-oci in the configuration because I need a connection to an Oracle DB. As includes, I took the oci.lib and oci.h from the same instant client sdk where I get the oci.dll from.
When I look at QSqlDatabase::drivers() it says “QSQLITE QOCI8 QOCI” so I guess, QSqlDriver did compile with oci.
But the moment I run QSqlDatabase::add(“QOCI”) there is an error:
Warning: QOCIDriver: unable to create environment
and lastError() says: Unable to initialize.
isValid() returns true, though.
I’ve already checked QApplication::getLibraryPath and made sure, the oci.dll is in the correct Folder but no success.
I added the path of the original location of oci.dll to PATH – nothing.
I’m going crazy. In 32-bits version everything went smooth, but in 64 bits…
Any help is greatly appreciated.
