I need the latest version of LabView and my package manager is too old so I have to upgrade it but I can't because the UPGRADER NEEDS TO BE UPGRADED.
but how am I supposed to upgrade an upgrader?
i would be sooo thankful if someone could help me.

Access Violation (0xC0000005) at EIP=0x778903EA
Hey all,
I get this error when trying to save an Excel report through LabVIEW and it then crashes my LabVIEW application. This only happens when I'm trying to save the Excel report; other than that the program runs normally on the target computer. It doesn't seem to be the LV code because the executable works fine on my development computer. I tried searching the forums but nothing matched this particular code of EIP=0x778903EA
Maybe it's to do with the different OS versions or Excel versions (2016 vs 2010)? (Win 10-development computer vs Win 7-target computer).
Any ideas? Thanks

Higher sample rate
Hi,
I was wondering if I could take samples up to around 5000Hz. Which adjustments do I have to make? Now it is going very slowly.
Thnx Simon

Transfer old code to new LV version
We have a lot of cRIO real time applications developed in LV 2011 and Windows 7.
Customer plan to replace old computers with new ones using Windows 10.
We definitely need new LV version.
Can we just copy old code to new LV version?
Thanks

Dual Channel Timer
Dear Labview Community
This is my very first Labview project, since Uni many years ago! I have tried to get my head around designing a four channel timing system, but can't seem to work it out. Please could anyone offer an help or advice...or general criticism to what I'm doing stupidly!
I want all four timers to start at the same time, this will eventually be from a physical switch connected to a DAQ, however for simulation purposes I'm using a Start button for now. I want each of the timers to stop independently of each other, again I want to use four stop buttons to simulate this, as I will eventually add beam break sensors or something similar. I have modified a vi I found online that I think might work, however I cannot seem to separate the stat/stop button.
I have only added two timers for now, as I thought it would be easy enough to add more once I had the logic figured out.
Any help or advice would be greatly appreciated
Thanks

Acquisition of analog signal with PCI-9820
Hi,
I have a PCI-9820 card and i've to do a continuous acquisition but after that i have to apply a 60MHZ frequency double internal and also do a kind of trigger so i can in a waveform chart a capture of this .
My questions are how i can apply the frequency to my signal ,and also how can i do the triggering ?
Thank you for any informations

Call Library Node Error 1097 with struct-by-value
Hi everyone,
I have the following struct definition and function prototype:
typedef struct TF_Output {
TF_Operation* oper;
int index; // The index of the output within oper.
} TF_Output;
TF_DataType TF_OperationOutputType(TF_Output oper_out);TF_DataType is an enum, I assume its size is four bytes but that might not be true. I need to pass the TF_Output struct by value, so I set up the call library node with this interface:
uint32_t TF_OperationOutputType_lv(uintptr_t TF_Operation, int32_t index);
Apparently, that is not correct and I get error 1097. The oper parameter is retrieved from another library function and should be valid. I tried different sizes for the enum and index but that did not help.
Am I missing something obvious? I would like to avoid building a wrapper dll, because there is no lib file and the tensorflow build process on windows is a rather involved endeavour..

How to Make a New Excel Tab After Every Loop Using a Write to Measurement File Function
I am new labview (I didn't write this code. but acquired it from a colleague). I have data I am collecting from a manometer. I am taking the readings in steps, moving parts with a linear actuator then taking readings again. At each step I am collecting data and taking a running average. For each step I want the data to be put in a separate tap so I can differentiate from each step and have the data processing to be easier. Thank you for the help.
I have attached a screenshot of my code below.

Horizontal reference line on waveform chart
I have a waveform chart which i'd like to add a reference line for setpoint and deadband. I can't seem to find any property nodes for markers which can easily set reference markers due to requiring a cluster for the waveform data.
How would I go about adding a reference line?

NI USB 7845R SPI protocol
Hi,
This is my first post, so please excuse my ignorance on any NI products and forum rules. I'm a university student and for my thesis project I want to use the NI USB 7845R with Kintex FPGA (http://www.ni.com/en-ca/support/model.usb-7845.html) in the lab to serve as an SPI master and send the baseband signal data I generated in MATLAB to my mixed-signal chip.
My chip has a Serial-In Parallel-Out (SIPO) register and an FSM that serves as a SPI controller. The SPI logic has been synthesized and tested using Verilog testbenches after place&route. In my testbench there, I wrote Verilog code that acted as an SPI master to verify correct data transmission. Now that I want to perform real-time chip characterization, I have to use the NI USB 7845R along with LabView to communicate with my chip. Thus, I was wondering, if NI provides some add-on for LabView that can implement the SPI protocol and configure the device accordingly.
Thank you in advance.

Report Generation Tool Kit doesn't work when built into executable.
Hello,
I am using the Report Generation Tool Kit to generate a Word document in a sub vi. The vi will initially prompt the user for some information and then it populates the report, ask the user to save, then closes MS Word. The code works perfectly in development, but when I build it into an executable, it does not launch MS Word, nor will it populate the data. I also do not see any error messages unlike other people who have encounter this issue.
From my research, I gathered that "NI_Word.lvclass" needs to be included in the project for it to work. However, the instructions on how to do that does not match what I see in the menus. Specifically, "NI_Word.lvclass" is not listed under the "Source files" tab in build dialog (see attached screenshot). Any help will be appreciated. Thanks.
Software versions:
LabVIEW 2017
Word 2013

BUG: Graphs automatically resizes when scale min\max is changed
When the Y scale of a small graph\chart is changed (just setting it doesn't work), the graph\chart is resized to some value...
Often this happens the first time, but in the examples I put a loop around it to make sure the demo shows the problem.
This was no problem in LV2013, but it is in 17 and 18. Haven't tried 14, 15, or 16.

Re: cRIO 9075
Hi guys,
I am currently working on a project which i use cRIO 9064 as my PMU. Also, i am using op4510(opal RT) simulator to simulate my power system model. My simulator provides +-16V output voltage, and 15 mA(max) output current. Since I don't want to use current/voltage amplifier which is needed to use NI 9225 and NI 9227 analog voltage and current inputs respectively, i would like to use another analog input modules except both of these modules(NI 9225, NI 9227) for smaller measurement range. I would appreciate if you could give me some suggestions.
Thanks in advance.

Blinking LED even without a property node
So I wanted to try this Blinking LED. Used the property node to get it blinking. Din't like it so removed the property node. Yet, the LED still functions with blinks. Attached is a GIF that shows it in action.
How so? The code is not super fancy but here it is

Installer build error
During build an installer, I got error saying "Cannot Cache Products", see attached error message. I searched online and NI provided suggestions
https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kJP2SAM&l=en-US
I tried the new directory, it still has the error. I cannot open LabVIEW as administrator.
The process kept going after clicking OK, I tried the built installer and cannot see anything wrong (I haven't tested every detail yet). Anyone can tell is it okay without the cache file?
