The nature of the error your seeing has to do with licensing. I've found one article over a year old that would indicate that a license file name is too long which is then confusing FLEXlm, a license manager. However I'm not sure I buy that one because I have license files that are over 30 characters long and my system seems to work. Your license files should be located at C:\Program Files\National Instruments\Shared\License Manager\Licenses.
I also found a article describing conflicts between different FLEXlm applications. That article can be found at

A couple of other things. Do you have administrative rights when logged on? Are you using the NI Volume License Manager (VLM)? Is the installation you are trying to preform from a network installation? Have you ever had LabVIEW work on this machine before? If so, what changed?
