Install LabVIEW 32-bit and 64-bit on same computer - doesn't seem to work

[wildcatherder]

I have the LabVIEW 2011 Development System.  The FAQ at http://digital.ni.com/public.nsf/websearch/71E9408E6DEAD76C8625760B006B6F98?opendocument&Submitted&&...  says that the 32-bit version and 64-bit version can be installed on the same machine.  I would like to do this because some of the targets for executables are 64-bit and others are 32-bit.  I have tried this on two different computers and wind up with two non-working versions of LabVIEW.  The license refuses to activate until I do a complete uninstall of both versions and pick one to reinstall.

Is there some trick to this or is the FAQ just wrong?

I have 2010 SP1 32bit and 64bit installed on one PC. So I cannot confirm your problem.

Never tried it out with 2011 which I use until now only 32bit.

Is there a good reason that the FAQ does not mention 2011?

I never had problems installing both. Do you use the default locations or are you possibly selecting the same location for both?

Is it a 64-bit computer?

Yes.  default directories

Yes.  64-bit computers.

You mention that the license wont activate the product until you uninstall and reinstall just one version. Are you installing the software for both versions and then trying to activate them at the same time? If this is the case, I would recommend starting with an install of 32 bit and activating the product, then install 64 bit and try to activate it. Also check the default directories and verify that the 32 bit version is installing under the x86 program files directory.

No, I installed them indivdually with activation after each install.  I did it with 64-bit version first and 32-bit second.  I'll try it the other way when I have half a day to spare.  They did install to the proper folders.

Install 32 first and then 64 . But either way both should be installed in the same directory and not in two diff places. 64 uses some shared files from 32.
