First HP Calculator virtual missing mfc120u.dll error since upgrading to version 1.21.8151.102

The first HP Virtual calculator will not start since the last update (version 1.21.8151.102). A windows system error window appears when you attempt to start the calc virt, saying: "the program can't start because mfc120u.dll is missing on your computer. Try reinstalling the program to fix this problem. »

Needless to say that "resettlement" has not fixed the problem. It is clear from research that the specified DLL is associated with related debug versions if you wonder if the last version was poorly built? Does anyone else have this problem? Any solution of HP? I had to go back to my "shipped" version that is less than optimal. It has been no problem so far with my device real first HP since the last update of the firmware so phew... but the virtual calc is very convenient when working on the PC with the code.

I am running windows 7 64 bit - all the latest updates applied to MS etc had no problem until this version of the vCalc

A possible scenario:

  • During installation, the 64-bit OS is recognized and installed the 64-bit version of the redistributable.
  • The emulator is probably a 32-bit version (compatibility, 32-bit programs usually work on 64-bit systems, but not vice versa).
  • There looking for the 32-bit version of the redistributable is not installed.

Note, this is one of the many possibilities in the world of software. However, the fact that 32-bit programs require the redistributable 32-bit and 64-bit programs require 64-bit redistributable is why I suggested to install both versions. It is not only useful for the HP emulators, but many other programs (this is why I have so many people already installed).

Best regards.

  • Satellite M500 - Missing TosHdpAPI.dll error message

    I recently installed Quicken 2011 and after installation, an error message appeared when the laptop starts:
    Cannot start the application... Missing ToshdpAPI.dll.

    I'm running Windows 7 Pro on a Satellite M500

    I have here a way to get a new copy of this dll?

    Hello

    I searched a bit using Google and it seems that TosHdpAPI.dll belongs to Toshiba Bluetooth software stack but he s strange why it is important for your Quicken program

    In your case I would try to reinstall the Bluetooth software which can be downloaded here:
    http://APS2.toshiba-tro.de/Bluetooth/

    If it doesn t help you should contact the manufacture of the Quicken program. Usually, they should know how you can get rid of this error message. They probably have a patch (update) for this problem.

  • error message trying to reinstall Java. tells me that the windows installer is missing a DLL error #1723

    My Java file must have been corrupted, but all of a sudden I can't play.  I have uninstall and when I try to reinstall I get afficherapres message "#1723 that there is a problem with the Windows Installer package. A DLL required for this install to complete could not be run.  Contact your provider staff or the support package!

    I also received his message - Launch4j - makes registry reference to a nonexistent Java Runtime Environment installation or the runtime is corrupted.  The system cannot find the path specified

    Help!  I tried to download the version of Windows Installer 4.5, but the website tells me that I don't need. I thought that the download would overwrite what is installed on my computer and load the missing file!

    Not sure if it is a Java problem, a problem Windows or Firefox...

    Help again!

    I've corrected the Launch4J message by changing the values of JavaSoft registry keys:

    Start RegEdit
    Open this key HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit
    Expand void keys and change all values your current value of JAVA_HOME JavaHome.

    If you have installed the Java SDK in C:\Program Files\Oracle\6 then use this value "C:\Program Files\Oracle\6".
    If you have installed Java Runtime Environment in the C:\Program JRE, then use the value "C:\Program JRE.

    You might be able to open a DOS command window and run this command to find the current path of Java:

  • Why am I messages DNS error since upgrading to El Capitan?

    Since I upgraded my OS to El Capitan I was making (Yahoo Search page) DNS error pages when I use an Internet link to leave my email to another site. Its pretty boring and I have to use Safari where it happens. I like FireFox, but if I can't solve this problem I will be forced to stop using it. Help, please. Thank you, Michael.

    You might have installed something more. On Mac, this problem is associated with some extensions Spigot, especially one named Searchme.

    Open the page modules using either:

    • CMD + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then on the side right, remove or disable Searchme - and anything else that you don't need, like all the other Spigot/MyBrowserBar extensions. Keep in mind that all extensions are optional and none is included with Firefox when you get it first.

    Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Is that what helps you regain control?

    This could be the tip of an iceberg of malware. When you install free software, you often get the options grouped under silence. I don't know the best way to 'clean up' a Mac of these elements, but you may want to consider the issue.

  • lsapiw32.dll problem since upgrade 9.3.3

    Hello

    Acrobat Pro Extended on Windows 7 Professional running.

    Installed the latest updated 9.3.3 today, and immediately after the restart, every time I start Acrobat, it complains that it cannot start because lsapiw32.dll is missing on my computer. I click OK and Acrobat makes the same complaint. I click OK, the second time and the program works, and as far as I tested it works.

    Anyone else seeing this?

    Thank you

    Gary

    So, to summarize, this problem seems to be limited to users with the TerraGo toolbar third (map2pdf) plugin.  There are two solutions - a workaround and the real:

    Quick and dirty: make an extra copy of the lsapiw32.dll file located in C:\Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins\map2pdf and place the extra copy in C:\Program Files\Adobe\Acrobat 9.0\Acrobat\.  With this method, there are now two copies of the file on your machine.  Total time: 1 minute potential for other problems: unknown

    A true: uninstall the TerraGo toolbar in your add/remove programs list.  Download and install the TerraGo toolbar updated to http://www.terragotech.com/products/terrago-toolbar .   Total time: 15 minutes.  Potential for other problems: still unknown, but if all goes well less than with the quick and dirty solution.

  • Script errors since upgrading Firefox

    Firefox is basically useless for the moment. I can't lose another day of work because of this problem. I am on Windows 7 and just updated to Firefox 37.0.2 two days ago. Since the update, scripts have been slow to almost zero the page loading. I have not loaded something again to my browser over the last two weeks. I'm not going to sit around test a bunch of crap then please don't even suggest it. Either someone has a fix for this issue or it please tell how to return to the previous version of Firefox. If I don't have this problem to be solved before the end of the day, I'm done with Firefox.

    Hello

    Refresh (called "Reset" in older versions of Firefox) can solve a lot of problems in restaurant Firefox as his default factory while saving your bookmarks, history, passwords, cookies, and other essential information.

    Note: When you use this feature, you will lose all the extensions, toolbar customizations, and certain preferences. See article Firefox Refresh - reset modules and parameters for more information.

    Refresh for Firefox:

    1. Open the troubleshooting information page using one of the following methods:

      • Click the menu button

        click Help

        and select troubleshooting information. Should open a new tab containing your troubleshooting information.

      • If you are unable to access the Help menu, type Subject: support in your address bar to bring up the troubleshooting information page.
    2. At the top right of the page, you should see a button that says 'Refresh Firefox' ('reset Firefox' in older versions of Firefox). Click on it.
    3. Firefox closes. Once the update process is complete, Firefox will display a window with the imported information.
    4. Click Finish and reopen Firefox.

    This corrects the problem? Please report to us!

  • Mfc120u.dll reports of Windows is missing

    I get an error message indicating that mfc120u.dll is missing. I have a laptop HP running windows 7, I ran a scan of the system with no result. How can I reload the missing file?

    [Edit Moderator: changed the title of "Bob Morton", 'mfc120u.dll reports of Windows is missing']

    It's that all the message says: "mfc120u.dll is missing" or is there more to the message than that?

    When you searched your system for the file missing is you find it?

    If the system is working properly, what do you think happened to him since the last time, that he did not work properly?

    Have you installed/uninstalled/updated of new programs or applications lately?

    These files that mfc name being part of Microsoft Visual Studio and there could be a number on your system then here is what mine looks like after searching that specific file:

    When you browse to your system that you see (or not)?

    I suggest two things:

    First of all, would you please change the subject of your column of "Bob Morton" more evocative of the question as:

  • Windows Update, error of missing mscorjit.dll!

    Hello world

    Yesterday, I turned off my PC, installed Windows Update 18 updated.  Restarts in Windows, I had several identical mistakes, informing me that several of my startup programs (i.e., programs that load at startup) were: "could not load the compiler (mscorjit.dll) Jit: it may be missing or damaged."

    Well, I spent all day yesterday uninstallation and reinstallation of these programs, as well as .net Framework 4.5.1.  But I have nothing has been able to restore the missing dll file.

    Finally, today, I have restored my entire PC from a backup disk, and everything worked perfectly again - no error about a missing dll.  BUT THEN... Windows Update has installed the same 18 updates and here!, I get the same exact errors on a missing mscorjit.dll!

    Among the 18 updates, I find these on .NET Framework, although I have no idea if these specific edits are the problem:

    A security update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x 64 systems (KB2911501)

    Update of security for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x 64 (KB2898855)

    A security update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x 64 systems (KB2898857)

    A security update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x 64 systems (KB2901112)

    Update of security for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x 64 (KB2901110)

    And in a subsequent update, after the first 18 and after the dll mscorjit disappears:

    Microsoft .NET Framework 4.5.1 for Windows 7 x 64-based Systems (KB2858725

    Help!  Why Windows Update would steal my dear old mscorjit?  And what do I do from here?
