I was having a similiar issue to some of what has been posted..
Every time you install something from NI, all the dependent/related
software pieces that come with the program you are trying to install
get updated also. For example, when I installed LabVIEW 8 Real
Time on my machine, it quietly updated the Datasockets installation
that was previously installed during the LabVIEW 8 base package
installation. Now the app builder requires me to put in the Real
Time disk in my drive whenever I build the installer. And it
requires the "December 2005" drivers disk, and the NI-RIO disk,
and the LabVIEW 8 disk. Grrr....
I used the following procedure to fix the problem. It involves
editing the registry. If you don't like doing that, then stop
reading now. I thought it was pretty simple, but your mileage may
vary .... proceed at your own risk ....
So I copied the entire LabVIEW 8 CD to "c:\CD\LabVIEW800" (I
decided to make the directory name the same as the CD's volume label
for my own clairity, you can name it whatever you want).
Then I ran regedit and went to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\Common\Installer\Distributions\
Under this key you will see a list of Class ID's (one for every NI CD
you ever put in your computer and ran an installation from).
Manually search through this list (you don't need to expand the ClassID
treelevel, just look at the top level of the classID) looking at the
key values on the right named "Title" until you find the one titled "NI
LabVIEW 8.0". Next to the key value named "Title" you will find a
key named "DistRoot" whose value will probably be "D:\". I then
edited the key's value and changed it to my directory on C drive that I
just copied the LabVIEW CD to.
You have to restart LabVIEW for it to recognize the new values ... and
remember you can always change the values back to D:\ if you need to
for some reason in the future.
I then repeated the above procedure for each of the CD's that my
application wanted. Now it builds applications without asking for
those dang CD's and it only cost me 1.8 GB of hard drive space and
about 45 minutes of time.... life is good again ... it's miller time.
Ps: Grrrr about LabVIEW 8 being sneaky and updating the LabVIEW
7.1 runtime engine to 7.1.1 (to a newer version of 7.1.1 than the one
available on the website no less), so when I had to reinstall 7.1 ...
my applications wouldn't run anymore claiming the runtime engine was
the wrong version even though I downloaded and ran the 7.1.1
updater. It wouldn't work again until I ran the LabVIEW 7.1.1
updated that is include on the LabvIEW 8 disk, Grrrr....
