 | I am in the process of rehosting my National Instruments software from a 20=
0MHz PC using Windows 2000 to a 866MHz PC using Windows 2000. The original=
computer was setup to use the PCI-6071E DAQ Board and the NI 5911 Scope Bo=
ard and I had no problems running VirtualBench-Scope. The NI 5911 came wit=
h NI-Scope Software Version 1.1 (500783B-00) which included Version 2.5 of =
VirtualBench-Scope. After installing NI-Scope 1.1 to the new computer, I r=
ecieved this error message:
"A subVI is not executable. The full de=
velopment version of LabVIEW is required to fix the errors."
Upon re=
ceiving this error, I went on line and searched the KnowledgeBase and found=
suggested solutions under "I Cannot Run My VirtualBench Instrument Because=
a SubVI is Not Executable". I investigated and tried all suggested soluti=
ons and still have the same error when I try to run the VirtualBench-Scope =
application.
Before I transfered the NI 5911 and the PCI-6071E to th=
e new computer, I ran the application Belarc Advisor to get a listing of th=
e programs and applications that were installed on the old computer. Below=
is a list of the National Instruments related programs:
NI-DAQ =
6.9.3
NI IVI Engine 1.83
NI Measurement & Automation Explorer 2.2.0r>GPIB Analyzer Demo
Add GPIB Hardware Version 1,0,0,1

Where do I find a corrected version of the SubVI that cou=
ld be causing this error? Is there another program or application I need t=
o install to restore VirtualBench-Scope to its original functionality?
<=
br>A solution to this would be greatly appreciated.
Thanks,

| Hi Richard M. Purser,
If you get this error, it is because VirtualBe=
nch cannot find a required DLL. Since VirtualBench is written in LabVIEW, t=
he LabVIEW engine reports the error about a VI not being executable and the=
full version being required to fix it. All versions of VirtualBench requir=
e NI-DAQ, VirtualBench 2.5 and higher also require NI-VISA and NI-IVI, be i=
nstalled. If these drivers are not properly installed then their DLLs will =
not be found and you will get this error. In your case, it seems like the n=
iscope_32.dll or iviscope.dll is not being found.
You may get this m=
essage if:
1. You don't have niscope_32.dll
2. You have multiple=
copies of the .dll's and they are different versions
3. You don't have =
iviscope.dll
4. You have multiple copies of the .dll's and they are diff=
erent versions
5. Any of the above dlls are not installed in the correct=
directory.
6. If your \vxipnp\win**\bin directory is not in your PATH =
environment variable, your PATH has spaces/invalid characters in it, or you=
r PATH is too long.
If you don't have niscope_32.dll or iviscope.dl=
l on your computer (Check by doing a find files) install the appropriate dr=
iver (NI-IVI, NI-FGEN, NI-SCOPE, etc). If you have multiple copies of one o=
f the dlls delete the older ones as well as any duplicates. If you have the=
dlls make sure that they are in a directory that is part of you PATH envir=
onment variable (go to a DOS prompt and type 'path'). If they are not add t=
he directory to your Control Panel > System > Environment Variables(NT/2000=
). If the directory is there make sure it doesn't have any spaces in it or =
anywhere before it or invalid characters. (All entries in the path must be =
in the DOS filename format of 8.3 characters.) Also there is maximum number=
of characters (127) that your path can contain, so if you remove any dupli=
cate entries and any directories that are not necessary, this can help as w=
ell.
Typically the problem is with VISA or IVI. The problem is the =
installer puts in the wrong entry for the path. Just adding a slash so the =
path is corrected should fix the problem but I have seen strange behavior a=
fter doing that. There is some documentation that states "to be sure of a f=
ix modify the LabVIEW installation to remove visa and either install it wit=
h VirtualBench or run the VISA 2.01 installer."
For you personally, =
I would first try to uninstall/reinstall NI-Scope 1.1 or install NI-Scope 1=
5. Let me know if the reinstall is successful!
