hey,
I'm having troubles downloading LabVIEW 2019 on my computer - windows 10.
I installed it once and then removed it from my computer, and now when I'm trying to download again I get this error message -
Anybody knows how to fix it?
Thank you.

Labview FPGA Auto Populate fields at compile time
Hello,
I am trying to do a unique version control and verification. Is there any way for certain fields/clusters to like auto-populate at compile time based on the compile? I want to have it so that based on whatever version is compiling it will fill out a cluster of UInt32s with certain data like timestamp (of version, not current timestamp) and version.
Thanks

Error during run of 2017 labview installer
I am trying to create a LabVIEW 2017 installer and i'm seeing several errors. When I first attempted the install (on a PC without any NI products), I was getting an error saying "you must install LabVIEW 2017 32-bit on the system before you can run this setup". I verified that I have unchecked the checkbox on the installer (in the 'Advanced' tab) saying "Require the LabVIEW 2017 32-bit development system", so I am not sure why I was seeing this error. I then installed LabVIEW 2019 and planned to mass compile everything and create another installer (due to co-worker's success on a different program), but when I did, I saw an error showing that I was missing a driver toolkit, "daqmx.rc" (see attached png). Given that I hadn't seen this with 2017 installer, I reverted back to the original installer and tried again, and now I see a different error when I run the installer (see attached png). This new, current, message says "Missing Key: [nimioi64.msi] Path … correct the ini file and try again". I'm hoping someone can give me a clue on what to do, as I have no clear direction at this point.

Using one button to start and stop
Hello
I am not a seasoned LabVIEWer so please forgive me for any mistakes.
I am trying to control data acquisition using one button to start and the same button to stop.
I would like there to be a start button because I want the program to be running to allow other functions to work before the front panel items are stored and data is acquired. (ie. allowing the user to change front panel items whilst the program is technically running).
I have attached a VI which successfully uses the start button to start the acquisition but requires a separate stop button to finish it. Any help in how to eliminate the stop button and any improvements on the current methods used would be much appreciated.
Kind regards

simulate temperature
Hello everyone
I have just created a VI which acquires a temperature from a simulated USB 9221 card.
I attach a pic of the code.
It works fine but I would like to see the temperature which changes from time to time (it's more realistic). Now it remains constant.
Is it possible to do that in Labview? Thanks

Test Random
Hello to all
I would like a vi that opens the source file, in txt format for the moment, and generates a number of random copies.
Entering the number of questions and the number of answers I divided the questions and now I would like to assign them a random position in a array but the result isn't I want.
Do you have any advice?

Does the Build.vi from the App Builder API work on Installer Builds?
I have been working with the app builder API to do some build automation experiments. When I use the Build.vi on an installer build in my project, it hangs. I have left it overnight and it didn't complete. The application builds work fine.
Does the build.vi work with installer build specs?

LabVIEW Indicator appearance and functionality
Hello,
I am new to LabVIEW and am required to support an existing application due to the retirement of a coworker.
I am attempting to insert a file path indicator to receive an element from an index array. The array is populated from a csv file that contains some application information. This particular item is a file path to a label format location. There is already a file path in the csv file that is being pulled in. I would like to just duplicate that functionality (i.e. use that as an example).
When I wire from the array element terminal, I am able to create a string to path object. After that, the existing item has what looks to be an object linked to an indicator. The context help for the indicator states that it is a file path indicator. I can't tell what style palette the indicator is from (Modern, Silver or Classic). When I go to create a new element in the index array, I can get to the point where I have the string to path object. However when I go to create the file path indicator, the symbol in the block diagram looks much different than the existing symbols used. In addition, the indicator on the front panel looks different and seems to have some different functionality. I have a fresh install of LabVIEW on my VM. When I go to the coworkers old computer, I am able to create the indicator and have the object in the block diagram look the same as the preexisting objects. However, there still seems to be something different in the front panel indicator. I suspect I am doing something different/wrong when creating this. I'm just not sure what.
Any thoughts or ideas on what I may be doing wrong would be appreciated. I apologize for the drawn out description. I'm not entirely sure I have the correct terminology.
Thanks!

Adding 1D arrays to a FIFO of fixed length
Hi.
I have a 1D image sensor producing samples, currently at 2Hz. The samples shall be added to a FIFO buffer to generate a moving average of each pixel.
Since the hardware currently is unavailable I'm trying to generate a small VI to simulate this, without success unfortunately.
FIFO1 gives an idea on what I'm trying to do but this adds every new array at the bottom of "appended array".
I would rather wire as in FIFO2, adding every new sample at the top of the FIFO but why is not this working?

Library error
The following errors have come up in a program I am working on. They both seem that the respective library can't find the VI but I've checked the program files and the files are included in the library so I'm not sure what the error is.

NI MAX crashing
Hello,
I've been having problems with launching NI MAX. Right after launching MAX, I see the splash window with the description "Initializing...". Shortly after this, another window comes up with the following message
NI MAX has detected an unexpected internal warning. Visit ni.com/info and enter the info code MAXKnownException for more information.
In the details section of the window, I see the following:
The CniDMFuiProvider::Initialize plug-in caused an exception in the CmxExecutionThreadPool::DoWorkNonUI function in the MAX process.
See this file for details:
C:\ProgramData\National Instruments\MAX\Logs\MAX\cfa87bbc-9467-4a1e-8425-a0f989b583d2\c97ebd86-9085-4d7e-8a21-c959fb281b93.dmp
I have restarted computer to see if behavior persists. Also I went into control panel and tried to do a repair on NI MAX.The problem is that when I open the program and right after the error message the program freezes and you can't go to different tabs to check the configuration. There is not a recent change e.g. upgrading the version or unexpected shut down, ...
I have attached a screenshot of the program error.
Any ideas on what my next step should be?

Updating Intensity Plot Live
This VI generates confocal images by iterating voltage values through the points a 2D raster waveform, and collecting fluorescence data at each point using the DAQ counter. The problem I'm having now is that the array of data plots only after it is entirely collected. I would like to be able to see it update live. I have seen some posts about using control references, but I'm not sure how to implement.
Attached are the VIs I'm referring to. GPScanTEST.vi is the main program.
Thank you for any feedback on this matter.

Error- 1073807360 occurred at Property Node
I am trying to create a VI which reads high or low with each loop in order to trigger a camera (https://www.adafruit.com/product/3202) to take a picture. After using the MakerHub>>LINX>>LINX Firmware Wizard for Arduino Uno and correct COM port, it indicates everything is connected properly. However, when I run the VI, it indicates Error- 1073807360 occurred at property note. I conclude that the Serial port is not initializing.
I have NI VISA installed and from there installed VIPM. From VIPM I installed LINX which is what I am using in this VI so LabVIEW can communicate with the Arduino.
On another post I saw a possible solution about explicitly opening all VISA references, but I am a bit confused as to what that does as I have gotten it to work without that function (VISA Open Function) before.

Continuous data acquisition in actor helper loop
Hi,
So, I'm trying to run a simple DAQ device (simulated) using a helper loop in the actor framework. Normally, the data read method is executed in a loop, so the only way I could think to avoid a loop inside of a loop was to place this function in the timeout event of the helper loop for this actor. This works but it causes other problems. For instance, if I add a stop event to pause the device and close all references, there is a lengthy delay between when I initiate the stop event and when the device actually receives the stop command. The delay is strongly dependent on the number of samples being read by the DAQmx Read.vi. Any ideas?

PWM on cRIO-9082 and NI 9401 Module
I am trying to display digital outputs on an oscilloscope using NI 9401 Module on cRIO-9082 but there is nothing.
I can display analog signals using NI 9263 Module on the same cRIO.
I do not know what I am doing wrong but I just cannot see the digital signals. If anyone has any idea please troubleshoot me.
Kind regards.
