LabVIEW 32-bit and Vista 64 registry read

Hi all

Having a problem with the reading of the registry to a 64-bit Vista with a LabVIEW 8.X EXE 32-bit machine.

I read a little on the issues.  Can anyone tell me is there a work around with LabVIEW 8.X?

I understand that Vista 64 divides the 32-bit registry and a 64-bit version.  Is it not possible to access (read/write) the 32-bit version of the registry by using a 32-bit application?

See you soon,.

Battler.

I have reproduced the whole of the hierarchy, but in this ZIp file is .vi ACI - WinAPI - open registry key (WOW64 support) (in the WinAPI\Registry folder).  It's almost a drop in replacement for the standard NI Open Registry Key VI (8.6).

It has a new option - access register.  You can select Native, 32-bit or 64-bit.  Native is somewhat level your application runs.  So 32-bit LabVIEW must Access the 32-bit registry on a 64 bit OS.  32-bit and 64-bit access to specific records.

If you try to run on a 32-bit operating system, the VI will force you in native mode.  The VI checks WOW64 support or 64-bit operating system (note that a 32-bit application will not indicate that it is running on a 64-bit operating system, that's why we need check the WOW64 support).  Based on the access register and the operating system, the code ORs bits suitable for security access.

You can find more information via Google and MSDN.

I have partitions installed correctly then they arnt the problem. If I try to boot from the recovery partition to install Vista 64 bit on a separate partition, to upgreade can leave, he simply don't say so, it doesn't allow the recovery or replacement of my existing Vista installation.

  • browsers (IE8, Firefox, Google Chrome and Opera) 32-bit and Vista 64-bit

    Hello

    I have a HP Pavilion dv2842se. I've had a little more than a year. IE 7 was originally installed with a version 32-bit and 64-bit. Not long after that I got it, the 32-bit version stops working. More specifically, as soon as I open the program it would be closed and completely unusable. I couldn't understand the question, so I installed Mozilla Firefox 32 bit and just used that. When the update of IE 8 came out, I downloaded and still had the same problem, so I continued to use Firefox.

    With the help of Mozilla has worked for me until about two weeks ago, when Mozilla started to become more and more reliable and now completely unusable. Assuming that it was a specific problem of Mozilla, I downloaded the 32-bit versions of Chrome and Opera and finished with all versions of four 32-bit navigation programs are the same.

    I realize that I can simply use the 64 bit version of IE8, as I did since I have no choice. However, there is a big problem with this. IE8 does not support Adobe Flash Player, which is required to run virtually all Web sites - including on the main site I use for my college classes. As the main reason that I bought this computer was for College, my computer as a whole is pretty useless to me without a functional browser that supports Adobe Flash Player.

    By the statement of HP, I tried to disable all add-ons, reset all internet settings and uninstall then reinstall Adobe Flash Player. I even on my own I've tried a system restore and scanned for viruses, spyware and software malware. Nothing has worked.

    Please, please, please if there is absolutely everything I can do to restore my browsers 32 bit in a usable state, please help me. I really do not have the money to buy a new computer, and 64-bit operating systems are almost now - standard, so there is no saying that if I bought a new computer for the same thing does not happen everywhere.

    Thanks for any help you can provide! It is much appreciated!

  • Sharing a Kodak printer between win 7 64 bit and vista 32 bit

    I have a kodak esp 3 printer connected to a vista 32 bit desktop pc. I share this printer on a wireless network in my house. I try to print from a laptop 64-bit windows 7, but failed to add this network printer to the computer windows 7. I think all I need are the x 64 drivers and add them via the systems vista printer properties.

    We now print by saving the document in the "Shared Documents" folder of mobile access and then print from the vista machine.

    After three long chat, phone and e-mail conversations with the technical support of kodak, what they say is this printer can't print wireless.

    They do not understand, it is a shared network printer, and I'm not trying to print directly to the printer via wi - fi, because I know that that does not support this printer.

    Any help, advice or where I could get a kodak 64 bit print driver would thank you very much


    Hi, I had not checked on this for a while, I couldn't get anywhere with x 64 drivers for Kodak for us would simply send documents on the Vista desktop, and then print them. So finally last night I upgraded the Office to Win 7, the upgrade price on Amazon is great-now $89, all problems are solved, put in place a homegroup print, share files and listen to music and video. Big difference in the performance of old desktop of 3 years. I should have done this 6 months he is a. sorry I have no solution to the original problem. Thanks - Matt

  • 995c driver required for windows 7 64-bit and vista 64-bit

    Need help, can't find drivers for my printer.

    Vidya says:

    You can try to install the Windows 7 printer drivers and use your printer's printing features. These drivers are available through Windows Update.

    Click Start, devices and printers, add printer > add a local printer > USB001 > choose the make and model > Windows Update > select HP, HP Deskjet 930c/932C / 935C, click Next and follow the on-screen instructions.

    Drivers Deskjet 990c would probably be a better game.  If your printer is connected through the use of network printer Add connection, add local printers, create a new Port, the Standard TCP/IP Port, the Next and then give the IP address of the printer.

    It seems that if the CD is read correctly, but if I interpret your message right, you have problems to install the software.  And if the facts are that it is a product of 16 - bit and Vista is a 64-bit operating system, you won't be able to install it.  Support for older, 16-bit software was removed from Vista and Windows 7.  You would need to consider using a product such as Microsoft's Virtual PC or VirtualBox from Sun Microsystems virtualization to run - and if it were a game, same virtualization may not work.

  • Question about Satellite L40 and Vista 32 bit

    Hey all, I have the following problem.
    I have Satellite L40 series 2 PC and tried to install vista ultimate 32 bit, and they freeze only on the process of "complete installation."
    I read in some other forums and found it is not only my problem. I tried with 64 bit ultimate, it's all OK. It may be, the main problem is that it is not possible to install VISTA 32 bit.
    I only ultimate now, so my question is if anyone knows or installed to another type of Vista 32 bit on these series?

    Thanks before

    As far as I know that all new models of Toshiba laptops come with Vista 32 bit. Satellite L40 is offered in three different models, and each one also comes with 32-bit operating system. If you have the recovery DVDs with your laptop is Vista 32 - bit OS. I assume it must be the Home Premium version.

    I don't have a model L, but my model works well on Vista Ultimate.

  • I am running vista ultimate 32-bit and 64-bit so the disk and to install 64-bit on a new PC.

    Salvation as above I am currently running Vista Ultimate 32 bit and have just bought a new computer that is running a 64-bit system, I have a product OPS windows genuine containing both 32 & 64-bit disc. How can I disable the 32-bit to install a clean 64-bit on a new HARD drive. I intend to use a drive to kill to wipe the HARD drive on my old computer but have read that others have had the problem, reinstall the 64-bit version as windows will not activate the license, any help or advice on this would be really appreciated.

    Thank you

    Hello

    I think your laptop could support 4 GB of RAM.
    If you are unsure, consult your user manual. It should there have mentioned what memory modules are compatible.

    But note; that can of OS 64-bit Vista uses the full 4 GB of RAM. The other 32 bit OS can see only 3.2 GB.

    If you want to use 4 GB of RAM, you must make sure that the Chipset, BIOS and operating system offers support for 4 GB.

  • Satellite A350 - Question about RAM and Vista 32 bit - 64 bit

    I bought a Satellite A350 Tiger Direct. He moved with Windows Vista 32 bit.
    It is capable in my view up to 8 GB of Ram. Vista 32 bit does support 3.

    All reviews on this laptop online say that it came with 64-bit and 400 GB of memory.
    Mine came with only 230 GB of memory and 32 bit vista. I ran Belarc advisor, and he tells me that my computer is 64-bit ready.

    Is this true? Why is - this me came not with Vista 64 bit?
    I want to upgrade my ram but with 32 bits, which is not possible and according to Microsoft you cannot update 32-bit to 64-bit.
    So should I buy Vista 64-bit upgrade? (for around 300 euros!). Is this in any way about this?

    What are my options? I want 4 GB of Ram or more really bad...

    What Satellite A350 do you have exactly?

    AFAIK the most recent series of Toshiba laptop pre-installed a dual operating system;
    In this case, you can choose between Vista 32-bit or 64-bit.

    To obtain the 64-bit, you will need to restart the laptop and have to press F8.
    Here you must choose the option to fix my computer. Then select Toshiba HDD recovery and finally, you should see the option which would be you can toggle between the 32 and 64 bit.

    Usually the Vista 32 bit supports 3.2 GB RAM.
    Only the 64-bit Vista will be able to recognize 4 GB and more.
