 | Sayaf,
I just ran the same IIOA installer that is available for dow=
nload on a clean Win 2K machine, and it all seemed to install correctly. A=
s I mentioned in my last post, there are several components missing from yo=
ur MAX directory - I will list them here so you will know what to look for:=
1) VISA - if VISA is properly installed, you will see visa32.dll in=
your C:\Windows\System32 or C:\WINNT\System32 directory. You should also =
see a file named niVISAui.mxx in your \National Instruments\MAX\UI Provider=
s\ directory. This is how we can tell VISA is not installed on your machin=
e by looking at your MAX directory.
2) The Assistant Framework - thi=
s component is what the I/O Assistant is built on. If it is not present, t=
hen IIOA will not work. You can tell that it is installed because there wi=
ll be a mxwTask.dll in your \National Instruments\MAX\ directory, and that =
is not there on your machine, either.
So something strange is happen=
ing here - Let's take a look at what the installer is doing:
When yo=
u run your IIOA installer, you should come to a tree that lists the differe=
nt products that will be installed. You will see under "Instrument Control=
" - VISA, NI 488.2, and Instrument I/O Assistant. Then you will also see a=
"NI Measurement and Automation Explorer 3.0.2". You can tell if the insta=
ller "thinks" these different components are already installed or need to b=
e installed by selecting the item in the tree and reading the text to the r=
ight of the tree - it will say something like "This feature will remain on =
your local drive" if it is already installed, or "This product will be inst=
alled" if it is going to install it. When you start over after uninstallin=
g everything, what text is shown when you select VISA? Does the installer =
think it is already installed? Or does it say it is going to install it?r>
Another helpful way for us to tell what the installer is doing is for=
you to log what happens during the installation - you can do this by runni=
ng the installer from the command line with the following syntax:
"=
C:\National Instruments Downloads\IIOA\1.0.1\setup.exe" \l*v c:\log.txt
=
This is assuming you downloaded the installer to C:\National Instrument=
s Downloads\IIOA\1.0.1\. After doing that, attach the log.txt created duri=
ng the installation and we can try to see why the installer is failing.
=
-Tommy
