How to install 64-bit version on 64-bit OS

[TruthOf42]

I am trying to install Labview 2011 SP1 Evaluation on Windows 7 64-bit OS. When I go to choose the isntallation directory it automaticaly points me to the 32-bit compaibility folder "Program Files (x86)". I believe this isntall the 32-bit version of Labview. I want to install the 64-bit version. How can I do this?

The evaluation version is 32bit and is fully compatible with 64bit windows. I am not sure if you can download the 64 bit version as evaluation. You can download the 64bit version if you click the [+] next to "Additional OS and Language DOwnloads of LabVIEW".

The 64bit version is 1.1GB.

For typical use, LabVIEW 32bit is recommended because it has wider driver, module, and toolkit support.

Why do you think you need LabVIEW 64bit?

You can easily install both if you are not sure. 😉

I need to install for 64-bit bit to replicate an issue that was seen with a 64-bit version of an SDK. Normally I would just use the 32-bit version.

Thanks

I had a 64 bit and a 32 bit version installed after the first version because there were some tools that I wanted to install that would not install on the 64 bit version.  There seem to be 2 different program file directories now: Program Files and Program Files (x86) so I'm assuming that they are for the two different versions of LabVIEW.  In the Program Files / National Instruments / LabVIEW 2011 directory there is a LabVIEW.exe file, but in the similar (x86) directory there is no LabVIEW.exe file.  It seems like there is no 64 bit LabVIEW version still installed in this computer. When I downloaded the CAN device drivers and installed the package, the sub VIs did not show up in the tool bar when I ran LabVIEW. However, when I look in the (x86) version files I see the CAN folder installed in the 64 bit program files directory!  Should I uninstall the current version and reinstall the 64 bit verson to fix this CAN problem, or is there another way to fix this.

This seems to be exactly the same as this question. Are you the same person?

You got it mixed up here. Microsoft decided that Program Files is always meant to mean the native version, which means that for Windows 64 bit, any 64 Bit applications get installed there. Program Files (x86) is for 32 Bit applications that will run inside the Win32 subsystem in Win64. Most NI Toolkit and driver installers only install into 32 Bit. So if you use LabVIEW 64 Bit you will usually have to copy the files from the Program Files (x86) directory into the according Program Files directory, making sure you maintain the same hierarchy.
