When using a 32-bit (x86) Studio Instrument in a Standard User Account on Windows x64, it will be required that you run your host application with elevated privileges.

This is due to 32-bit programs having limited access to critical parts of a 64-bit operating system.

In Windows Vista, to run the program with elevated privileges, right-click on the Studio Instruments' (or the host application's) icon and select "Run as Administrator".
