Using a U6 on Windows 10 I successfully installed the Feb2016 beta version.  LJControlPanel informs me that a firmware upgrade for the U6 is available.  I exit that program and launch the LJAutoUpgrade program.  When I run that the fun begins.  I go to the download page, which appears to be a custom web browser interface, and it shows me three files.  Which one do I need?  Or perhaps all of them?  I don't know.  So I pick one (the hex option).  Where did it put that file?  I don't know.  The AutoUpgrade program tells you that the file must be in a specific directory, but the download program didn't put the file there.  In fact that directory does not exist.  Could you please find a way to make this simple process more difficult?

There is no custom web browser interface in LJSelfUpgrade. The link opens the default web browser on your computer and goes to the firmware section of our site. On this page, there are links to the firmware pages for specific LabJacks. On the U6 Firmware page, there is currently only one firmware file, U6firmware_143_04222015.hex, and underneath that are links to beta and old firmware pages. Perhaps you are confusing the beta and old firmware links as files.

Download the firmware file, which for the U6 is a .hex file, to somewhere on your computer. Where this file downloads is based on your web browser's settings but likely its in your user's Downloads folder. In most browsers you can right-mouse click the file link, and select "Save Link As" to specify the location. In LJSelfUpgrade click the browse button, browse to the hex file on your computer and select it. Then press the program button.

I will agree the "Download any desired upgrades and save them in the \LJSelfUpgrade\upgradefiles\ folder" is outdated and confusing as we no longer create that folder. It should say something like "Download the upgrade file and save it to a folder on your computer. Click Browse, navigate to the file and select it. To download the latest firmware upgrade file ...". I'll look into having this text updated in LJSelfUpgrade.

Thanks for your input on the firmware upgrade process, and let us know if you need further assistance.

Also, there is a LJSelfUpgrade page for the U6, and it looks like it needs some updating regarding the "\LabJack\LJSelfUpgrade\upgradefiles\" folder.:

When setting up U3 installation package the process downloading required files does not complete.  What should I do

Submitted by DRichmond on Thu, 11/16/2017 - 02:54
drichmond@videalert.com's picture

I am looking at using the U3 on a Windows 64 bit platform.

I have downloaded the basic installer, as I want to purely put the DLLs on the target system. There is a X64 directory but it only contains LIB files and the root directory contains a single DLL. It is most unusual that the same DLL supports 32 and 64 bit, so is there a DLL missing from the basic installer package?

Thanks, Dave

LJUDDotNet.dll, which I believe you are referring to, is a .NET assembly that is both 32 and 64-bit compatible.

The main driver, LabJackUD.dll, and its USB support driver, LabJackWUSB.dll, have a 32 and 64-bit version like you expect in the in the following folders:

32-bit: C:\Windows\SysWOW64\
64-bit: C:\Windows\System32\

The .lib files link to LabJackUD.dll when building your C/C++ application.

I am NOT installing the full package, just the basic installer. I am NOT using .Net.

Below is the full directory tree post install of the Basic Installer.

There is no LabJackUD.dll or LabJackWUSB.dll. Are they missing, or is there a further install step to be done?

 I have not plugged in any device yet.

 

Thanks, Dave

.dll files are installed to C:\Windows\SysWOW64\ or C:\Windows\System32\. Please check those directories.

32-bit: C:\Windows\SysWOW64\
64-bit: C:\Windows\System32\

My apologies, have found them.

Why do you not distribute an SDK with separate headers, lib and DLLs files for 32 and 64 bit?

We want to put the labjack DLLs with our executables outside of the Windows system32/syswow directories. Will this be possible, or do the DLLs need to be visible to Windows at boot time?

This is for a very tightly controlled Windows Embedded system.

Thanks, Dave

The header file is bitness independent. (The same .h file is used to compile on both 32-bit and 64-bit.)

The .dlls are installed by bitness:

32-bit: C:\Windows\SysWOW64\
64-bit: C:\Windows\System32\

The .libs are installed by bitness:

32-bit: C:\Program Files (x86)\LabJack\Drivers\
64-bit: C:\Program Files (x86)\LabJack\Drivers\64bit

You should be able to put the .dlls wherever, as long as your application can find them when it tries to load them.
