We have a LabVIEW application, which has a LabVIEW-based Installer. This LabVIEW installer is called from within another Inno installer (since our main Inno installer pulls together multiple components, most of them not LabVIEW). Whenever this Inno installer ends, it always asks the user to restart their PC, even if the LabVIEW installer was cancelled.
I narrowed it down, and it's reproducible with only the LabVIEW installer, so it's definitely LabVIEW installer's fault. According to Inno's help documentation, "if a program executed in the [Run] section queues files to be replaced on the next reboot (by calling MoveFileEx or by modifying wininit.ini), Setup will detect this and prompt the user to restart the computer at the end of installation." However, as stated above, this dialog is triggered even if the LabVIEW installer was cancelled and wrote no files.
Now, the above linked documentation refers to a flag I can put in my installer script to ignore this restart dialog, but it's a global flag, and I would like my other installers to still make use of this handy restart dialog if necessary. Unfortunately it seems LabVIEW installers trigger this even if not actually necessary.
Has anyone seen this before? Any ideas how to make my LabVIEW installer NOT muck around with the MoveFileEx or wininit.ini stuff if/when it's not actually needed? Attached is a LabVIEW project and Inno Installer script which easily reproduces the problem. To reproduce:
Extract the attached .zip Open test.iss in Inno Setup and click the "Run" button Alternately, just run the built installer under "\Output\test_inno_installer_188.8.131.52.exe" Click Next on 'Select Components' dialog Click Install on 'Ready to Install' dialog When LabVIEW installer pops up click Cancel, then yes (you're sure) See the Restart dialog Thanks!
Reposting this here in an effort to gain some traction because it's absolutely killing me.
I'm trying to build a standalone .exe with a VI that contains a Scilab script using the Scilab gateway. On the actual program I created I get an error message stating that the front panel cannot be loaded on the SubVI that contains the Scilab script node. If I delete the node the program runs fine.
I decided to create a very basic VI containing a Scilab script to troubleshoot, and I get the following error: "This VI is not executable, The full development version of Labview is required to fix the errors". I don't understand this at all, since I do have the full development version of labview. Also, the code runs fine as a native VI, and this error is occuring on my development machine, so all required files should already be in the correct locations. Additionally, I've added "ScriptScilab.dll" as an always included source file and it's in the correct folder for the runtime engine. In fact, I've tried it in multiple different locations (app data directory, app root directory, LV2017 root directory, etc...) and still nothing.
What am I missing here? .Zip of may sample application attached.

I'm finally implementing a long-delayed transition from our homebrew LabView build system to Jenkins.
The best build-step option (for Jenkins under Windows) seems to be "Execute Windows batch command". My batch command looks like this:
pushd "directory-containing-lvproj" echo "Running LabVIEW build process..." start "bogustitle" /wait "C:\Program Files\National Instruments\LabVIEW 2017\LabVIEW.exe" "Build.lvproj" "BuildJenkinsProject.vi" echo "complete, errorlevel %ERRORLEVEL%" popd where BuildJenkinsProject.vi is set to run when opened. BuildJenkinsProject.vi reads some environment variables set by Jenkins, sets up the builds (multiple EXEs and installers defined in a different lvproj) builds away.
But my builds take a while, and I'd like to see the output from my logging system inside Jenkins while the build is in progress. Some Googling turned up these posts re: sending output to stdout from LabVIEW:
I'm running LV 2017 64-bit, and none of the existing examples were handling 64-bit HANDLEs correctly, so I wrote a new version. This version uses only WinAPI calls (vs WinAPI + .NET), fixes some bugs, and it stateless, so you can call it anywhere in your code. Even when flushing the buffer after every write (which some on the Internet claim is necessary to get real-time log output; I am skeptical) it is plenty fast, around 10,000 lines per second. Since jdunham had previous written a fancy object-oriented logging system, I subclassed our logging system to write to stdout as well as the regular log. When I build from cmd.exe using the above batch file, it all works as intended.
My problem: when Jenkins runs my batch file, I get something rather less exciting: nothing!
E:\Jenkins\workspace>labview\Build\BuildJenkinsProject.bat E:\Jenkins\workspace>pushd "labview\Source\Build\" E:\Jenkins\workspace\labview\Source\Build>echo "Running LabVIEW build process..." "Running LabVIEW build process..." E:\Jenkins\workspace\labview\Source\Build>start "bogustitle" /wait "C:\Program Files\National Instruments\LabVIEW 2017\LabVIEW.exe" "Build.lvproj" "BuildJenkinsProject.vi" E:\Jenkins\workspace\labview\Source\Build>echo "complete, errorlevel 0" "complete, errorlevel 0" Not a big deal since I have my regular log files, but having gotten this far it would be nice for Jenkins to show work-in-progress. Any ideas? In the meantime, here is a stdout writer. (Released under MIT License, copy away.)

I use Labview 2015 32-bit on a 64-bit Win& pro computer. My application connects to Hardware using NI-VISA and NI-DAQmx only (Two RS232 communications via a VCOM port and one NI DIO card using DAQmx).
Until today, I was building an executable which I was copying through the network on another win7 pro machine in the lab next to the hardware. It was working fine with Labview Runtime 2015 installed on this machine along with NI-VISA and NI-DAQmx. I never used an installer, I installed those 3 components seperatly.
Yesterday I added some features to the application and the EXE won't start. I have an error msg saying "The VI is not executable. The full version of Labview is needed to fix errors". The machine in the lab can't run the EXE but the EXE won't even start on my development machine.
My previous EXE from last week still works fine. The code works fine with all new features if I run the main VI from the development environment. I've double check all of my licences status. If I open another project and compile the EXE, I am able to run this EXE (I use a complex app containing almost all the same software components) If I build an EXE with a different UI source file part of the same project, that EXE works fine. If I build the EXE from my previous version again, it works fine too. I tried removing all the new features I had added in the project and build the EXE again and I still get the error. I tried creating a new project file and import the same librairies to try building an EXE from a fresh project file and I still get the error. I tried installing Labview 2015 on another computer and try to build an exe from a fresh labview install on this computer and I get the same error. The development machine can't execute the compiled EXE) It has to be related to the code but, I can't roll-back and get functionality of the EXE again unless I totally replace all of my files from a backup made last month. The most recent posts I read from a similar error are from 2013 and later. And the problem described is always that the EXE does not work on the deployment machine but works fine on the development machine. I must be at version 25 of this application to which I add improvements on a regular basis since almost 1 year. I am really puzzled. Is there a way to analyse or get more info about the broken EXE error? All the new features I added are using components that were already present in the project and in the main VI. The new features are important, I'd really like to use this working code with the hardware as soon as possible but I don't really want to install labview on the development machine.
Any ideas? I don't know what to try next. What would be the best information to provide / look for for the next step?
Thanks to all in advance
