Serial will not connect unless MAX has been started

Hello All,
I am using Labview 7.0 , MAX 4.6.0f1, NI-VISA 3.0, Windows XP. A Microchip PIC USB device is attached to the Labview PC, the PIC embedded code registers as a Virtual Serial port and behaves as expected, I use Labview to read and writes simple fames of text.
I found I can communicate ok with the device and need to create a distributable Application, this is where I have found problems. I installed the application on a different machine but I don't see any serial COM x text in the serial drop down list. I was expecting similar function to the device manager which enumerates serial ports on the fly (including the PIC i am using)
Having read a few posts  it looks like I need VISA runtime. I thought I was including this in my application as I selected, Tools > Build Application>Installer Settings> Create Installer X > Advanced > Serial Port Support. The only thing that seems to make the application pick up the serial ports is to run MAX first. I would prefer not to force users (15 to  20) to install MAX and then have the Labview automate a MAX startup when the program is started. This seems a bit clunky.
Advice appreciated
Thanks Chris

Hello Jamie,
Thankyou for the responce, I have tried ( and tried ) to get this to work without success so far.  I downloaded NI visa301full.exe and followed the instructions regarding the batch.bat file however when I finally got the visa install popup to appear it progresses to the progress bar window, the progress bar fills to about 30% for 1 of 16 then removes the progress, waits a few seconds then part fill the progress bar again, and repeats over and over till I cancel. After some reading I noticed the batch file is only needed for multiple exe install so I removed the batch file and have been trying to call the visa301full.exe directly to make things simpler.
I tried manually installing the visa301full.exe and this worked fine, so at least I can see my application and visa301full.exe working together when they are installed. Ive attached my build file as hopefully Ive done something daft there. I think its probably nearly there, I appreciate your help and advice.
Regards Chris

  • I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to.

    I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to. I can't find anywhere in the utility or network preferences that will allow me to choose this router as the default. How do I fix this? BTW I'm using Lion.

    Are there any previous networks that you have used that have the same password as Molly?  YES
    Using System Preferences > Network > AirPort Advanced again, you need to remove any listings of previous networks that used the same password as Molly. Click the name of the network and click the - (minus) button at the bottom of the list of connections.
    Also delete any other networks (except Molly at the top of the list) that might have used the same name...Molly in the past.
    Delete any other networks that you no longer need so that your Mac will search for networks more quickly
    Click OK, then click Apply
    Open KeyChain Access and look for a listing of any old networks that you no longer need. Click to highlight the name of the network, then click the Delete Key on your computer.
    Then look for any old networks that might have used the name Molly in the past and do the same for them.
    Then look for any old networks that might have used the same password as the password for your "new" Molly network and delete them in the same way
    Click the KeyChain Access menu just next to the Apple icon in the upper left corner of the computer screen
    and then click KeyChain First Aid
    Enter the main administrator password for the Mac you are using and highlight the Repair button. Then click Start. You will see a message that repairs have been completed
    Quit Keychain Access
    Power down the entire network...all devices...order is not important
    Power up the modem first, then your main router, the other devices one at a time
    Log on to Molly and see if the Mac remembers it after a few tries. If not, I'm afraid that you will need to change the name of the wireless network and password on your router due to corruption issues on the Mac. You have done everything possible without re-installing the complete operating system.

    I get as far as what appears to be restoring my phone then when the software has downloaded, iTunes insists on my phone accepting it's access. I had carried out this action two weeks ago when I had the same issue on my phone and managed to restore it successfully, but it isn't happening now. I have updated iTunes to the latest version since the last time, and also my iPhone to the latest version.  I have had endless trouble with this phone so having gone through all the steps suggested in various forums it is clear that it is an issue with the phone, not helped by the recent iOS and iTunes updates with stricter security.

    Try resetting up the AirPort base station to see if it resolves the connectivity issue. Also make sure you are using the recommended settings to connect to the internet.

    I searched other posts and someone suggested that I go to setup on the front of the printer and then tools. I did a cleaning twice and now it makes copies again. The first time I did the cleaning it still did not work, the second cleaning did it. I would strongly suggest to HP that they address this issue in their troubleshooting docs. They don't even mention not making a copy, they only talk about printing, two diiferent issues. 

  • Songs purchased through iTunes on iPhone 4 get download error and will not load.  Account has been charged for the purchase.

    I purchased an album through iTunes on my iPhone 4, and my PayPal account has been charged for the entire album.  However, all but 2 songs would download to my phone.  The other 2 have a download error.  Any suggestions on how to fix the error, or to get a refund for the songs that I can't get?

    katrina posted this. i did everything, but what worked was the misconfig. thanks again katrina.
    top fixes for a new iTunes install/upgrade are
    - turning off security software such as Norton before the install as Apple suggests
    - installing QuickTime standalone, not regular
    http://www.apple.com/quicktime/download/standalone.html
    - setting up Norton to allow iTunes
    - scanning for malware with ewido (Free at www.ewido.net/en/)
    - last but not least, using MSCONFIG to find Windows conflicts

  • The error, "Restart Required. Lightroom has encountered a problem with its menus. Some menu commands will not work until Lightroom has been restarted" appears in Lightroom.

    I updated to 5.7 a few days ago and I just now encountered this problem while importing some photos. Is this a common problem?

    Hey Guy's, Thank you for the recommendations to fix his problem and I did restart my browser, etc.. and all was corrected. But, I have been with Lightroom for a while, starting with LR3. I can not remember having one problem, except for my errors, until I started with LR5 and I have some kind of problem hourly! I do not have many presets or plug-ins so I don't think that was really a problem. It crashes constantly, I can edit 4-6 photos and then it starts slowing down and I have to do a restart. It does, on occasion, jump around from the develop controls and even changes modes, crashes and sometimes I just wait it out and it will open in the print mode or slideshow! I find photos all over my computer that it sent on its own. I did download and check for malware and other viruses and none were found so I am still troubleshooting everything from my fairly new computer and everything else but I always think when they come out with a newer version to download, it will correct my problems but they only get worse.

  • V3i unlocked phone will not connect with itunes. has anyone figured dis out

    i got a v3i itunes phone i plugged it into my mac. and it work for a min.
    now it's not being recognized at all, i tried reformatting the storage chip
    i reset master phone settings. i got this phone for the itunes foremost,
    now i'm bout to use it to level my washer machine. a use my old phone.
    can anyone give my some help?

    I have a V3i, and suffered the same issues. Here's how I got it to work.
    1. Reformat memory card
    2. Reset phone.
    3. Repaired permissions on my main volume. Repaired disk [it was ok]
    4. Restart computer without phone plugged in.
    5. Select USB Port on computer [e.g. not a monitor or keyboard USB]
    6. Once computer is running, do not open iTunes.
    7. Plug in phone to USB port referenced above.
    8. Place your hands in the air, and resist the temptation to touch anything. USB1.1 is sllllloooooowwwww. Allow up to 5 minutes to do nothing before you give up on this step. Look at the system clock to make sure you don't wait too short or two long.
    9. iTunes will auto-open.
    10. iTunes will throw up a pop up box. It lists the name of your phone, and gives two options: AutoFill and Use as a Disk. Slow down, and take a deep breath. You really don't want either of these options. However, you want to Autofill more than you want to use memory card as a disk.
    11. Allow 15 -20 minutes for iTunes to load songs. You'll be able to watch it work, so you'll have comfort everything is going to plan.
    12. After the first autofill you can move songs around as you please.
    Good luck

  • HT1695 Wi Fi on ipad 3 will not connect to internet - had been working until yesterday

    My wi-fi was working fine two days ago and yesterday morning.  It stopped working and cannot connect to internet. I have tried all that is recommended except downgrading to next level iso.  Please help - I took to another location to see if it was my network, but not so.  I have two other computers connected and the whole house DVR system.  These items are working fine.

    What does, "tried all that is recommended mean"? What have you tried?

  • Mac shutdown will not complete if Firefox has been opened since boot

    Shutdown command clears my desktop, but the spinning bars appear ad infinitum, and my G5 has to be powered off. I was using only three applications: iTunes, Safari, and Firefox. Through testing, I have determined that the problem doesn't occur after I have opened Safari by itself, or iTunes by itself. Shutdown hangs only after I have opened Firefox.
    == This happened ==
    Every time Firefox opened
    == Every time I tried to shutdown my G5 in the past three days.

    First, try upgrading Firefox to the latest version, 3.6.3. See [[Installing Firefox on Mac]] for details.
    If it still happens, see if quitting Firefox before shutting down fixes it. Go to the Firefox menu and choose Quit.
    If it still happens after updating to 3.6.3 and after quitting, check the Activity Monitor after quitting Firefox to see if "firefox" or "firefox-bin" is still listed. The activity monitor is located in /Applications/Utilities. In this case, let me know if it's still there after quitting.
