Installation Problem : Fatal Error!!Required NIPathsDir Property LV80DIR is unspecified

[cambridgeguy]

Hi,

I have problem installing Lab View Student Edition 8.0 on my laptop running on Windows XP Pro (with service pack 2).
It says:

Fatal Error!!Required NIPathsDir Property LV80DIR is unspecified.

I seem to be able to install on my desktop running the same operating system, but i really need it on my laptop.
Help?

Thanks.

Hi cambridgeguy,

I have heard of similar problems which resulted from a corruption in the operating system (not good news unfortunately).  A good debugging step would be to try installing something else to see if the trouble is constant through all MSI installers.  Perhaps you could try installing our DAQ drivers and see if you get a similar error.

Let us know!

Thanks Megan for your reply! : )

You are right, the error was due to corrupted windows registry.
Part of the windows's registry was referring to drives that doesn't exist, causing installation problems.

I found the link helpful in fixing this registry problem.
