could not load front panel

[dmorris]

I was given an application by a hardware vendor (a test program for their device) that was built via Labview (I have only the .exe).  When I try to start it, I get a bunch of "could not load front panel" errors, all of the form:

LabVIEW: Resource not found.

An error occurred loading VI '[x].vi'.  LabVIEW load error code 3: Could not load front panel.

[x] is the only difference among the four errors I get, where [x] is:

* NI_AAL_Pro.lvlib:Unwrap Phase.vi

* NI_AAL_Pro.lvlib:Real FFT.vi

* NI_AAL_Pro.lvlib:Scaled Time Domain Window (DBL).vi

* NI_AAL_Base.lvlib:Mean.vi

Basically every post I can find on ni.com about "could not load front panel" suggests that this is a build-time problem, i.e. that the developer forgot to check a box that would force the missing components to be included, which doesn't help unfortunately... but here's the twist: when I move this to another machine, it works fine.  I don't have LabView installed on either machine.  Both are Win8.1 x64.  I believe the application was built with LabView 2010.

The only relevant difference between the machines that I can think of is that on the machine where the application *doesn't* work, I use many National Instruments device and have installed DAQmx.  You'd think that if anything, that would install missing components and make this *less* likely to happen.  

Since encountering this problem, I've tried to install every Labview 2010 runtime SP/patch I could find, but unless I'm missing something, there's not really a definitive place I can do to make sure I have all the patches or get a single cumulative rollup.

Any ideas?  I don't have access to LabView or the source .vi, but the fact that it works on a second machine suggests there's hope.  I really want it to run on my primary machine, where all the relevant hardware is.

Thanks!

You are most likely missing lvanlys.dll.  It should have come with the installer that the exe distrubuted on.  You "Should be able to add a copy of it to the exe's support directory.

Is it possible that one machine only has the minimum run time engine (~42MB) installed? You need the full standard version (~180MB).

I don't know how to check whether I have the "minimum" or "full" runtime installed, but when I try to install the runtime version you linked to (2010SP1f5), I get an error that says:

Cannot install
NI Variable Engine (higher version already installed)
DataSocket (higher version already installed)
USI (higher version already installed)

...and I'm prevented from clicking "next".

I don't know whether this is good or bad news... presumably it means I already have 2010SP1f5 installed.

That is good news.  did you look to see if the dll was in the support folder?

For all of my deep fussing with DLLs, it turned out all I needed to do was run it in Win7 compatibility mode.

Problem solved!
