How to install the VISA 64-bit runtime library?

[andreas.eckstein]

Hi! I'm trying to install NI VISA 5.2 (from visa52full.exe) on Windows 7 Pro 64bit, and I'd like to use 64bit libraries to control my instruments (I'm using Java/JNA, and can only interface 64bit libs with 64bit java, and only 32bit libs with 32bit java). However, after installation I cannot find visa64.dll, and in the installer I can't find an option to force installing the 64bit libraries. Can someone point me in the right direction here? Thanks in advance.

Actually, consider my question answered. I just realized that Dell sold us a computer with Win7 32bit pre-installed, instead of the 64bit version we ordered.
