what disk path is really being checked when grid installation fails with PRVF-9802?

  • Remove VMware completely when the installer fails - HOW?

    I had VMware Workstation 8 works fine on a 64-Bit machine of Windows 7.

    I bought 9 Workstation and tried to install it, and he says that he should uninstall version 8.

    Well, it failed.  Now, I can not install ANY version, version 7, 8 or 9, all versions.

    The installer is apparently unable to deal with an error to uninstall an earlier version. Why?

    [at this point, Monday, December 17, 2012, it is all fixed with VMware technical phone support. It involves several

    steps and a key was to use the utility Fixit from microsoft from here: http://support.Microsoft.com/kb/2438651/en-us

    and 1308 VMware knowledge base article http://KB.VMware.com/kb/1308 .

    Microsoft fixit scanner not found VMware, but she showed 'unknown' (or other?) and VMware

    technical support took the key to the article above of 1308

    {0D94F75A-0EA6-4951-B3AF-B145FA9E05C6} HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

    Paste in the registry key when asked by the fixit utility

    {0D94F75A-0EA6-4951-B3AF-B145FA9E05C6}

    Who noted a mistake and fixed it.

    My options are:

    1 reinstall the Windows operating system and start from scratch (which will take a few days to catch up with installed programs).

    NOTE: DON'T DO THIS WITH THE SUPPORT OF VMWARE

    2. remove all vestiges of the previous installations of VMware so I can install without being told that the installer has found another version.

    NOTE: THIS WAS DONE BY THE TECHNOLOGY WITH THE HELP OF THEIR CONTROL PROGRAM REMOTE

    ------------------------------------------------------------------------------

    They have the option "/ clean" on the installer, which does not work, but it must do what he pretended to do so, remove all previous keys and elements.

    What a VMware solution that fixed what well Setup obviously cannot fix. It should prepare my computer so it will NOT report versions of VMware if I can install two versions 7, 8, or 9.

    -------------------------------------------------------------------------------------------

    With the help of VMware support, they were able to completely remove VMware and install VMware 9. I'm going to

    to try to writeup that they did, but the solution took about 30 minutes and many find and remove the

    Directories of VMware.

    I now have version 9 installed and it works fine.

    Post edited by: jeff92677 - TO EXPLAIN THAT THE PROBLEM IS SOLVED, AND THANKS to VMWARE for THE SOLUTION

    This feature was introduced in WS 7.
    Since then WS installers often think that older versions is present - and this happens even on systems that has never ever been before WS.

    On the issue of the port... This is normal. Most of the time it does not configure the port correctly during a first installation.
    You have installed Skype? -Make sure that remove you it temporarily.
    Then stop vmware - pass manually - change the
    C:\Documents and Settings\All Users\Application Data\VMware\hostd\proxy.xml
    -use an equivalent path for win7 of course - so that it uses the port you want.

    445

    Then restart vmware - pass and it works hopefully

  • What happens if the network goes down when the broker DataGurad (with fast failover) is configured?

    Hello Experts,

    We have configured Dataguard in our environment, now anxious as the broker. But we have some queries.

    1. what happens if primary fails (failover or passage)?

    2-if failover occurs, go back manually when the primary is available?

    3-if Eve falls down, how would react broker?

    4 - If the network goes down (for any reason) for some time, observer cant find primary and standby, how would he react then?

    Please help me with your advice.

    Thank you and best regards,

    Vignacourt zerwali.

    Hi David,

    Let me put in a way if I understand your question. So, you have broker + observer configured in your environment. FSFO occurred which means your watch becomes primary and is running. Then after some main real-time is alive and what will be the observer will do here. ? right. ?,...

    If my interpretation is correct, here is the answer,

    (i) when the old primary remains alive, just bring up the State. The observer resets automatically (if its market) the database, bounce the old primary and synchronize with the new primary (i.e. your old database pending). But remember that your old primary will undergo sleep role yet...

    After the process described above,

    (II) If you want that your old primary again, we have to do a manual failover to get your old configuration.

    Hope he would have deleted you. !!

    Kind regards

  • Installation fails when wake update 10.1.2 in 10.1.0 - Package MSI

    Hello.

    I need help.

    After "slipstreaming" in the 10.1.0 10.1.2 update Player Package MSI - installer fails with the message:

    [quote] Error 1334. Cannot install the file 'adobearmhelper.exe' because the file is not found in the file 'Data1.cab '. This may indicate a network error, an error reading from the CD-ROM, or a problem with this package. [/ quote]

    The system is W7 SP1 with the latest updates. Without anti-virus running. Working under the account administrator (SYSTEM and console).

    Reader 10.1.0 I joined the 10.1.2 update as follows:

    [quote] msiexec /a AdbeRdr1010_en_US.msi /p AdbeRdrUpd1012.msp [/quote]

    Update runs successfully.

    Extract the Data1.cab of the new integrated package shows: 'adobearmhelper.exe' is missing.

    Extract AdbeRdrUpd1012.msp shows: adobearmhelper.exe is here.

    The 1 - Mio.-$-Question is: why the wake not working / integrate all the correct files?

    Very funny: when I download the AdbeRdr1012_en_US.exe of ftp://ftp.adobe.com/pub/adobe/reader/win/10.x/10.1.2/en_US/, extract the .exe and take a look in the Data1.cab-> adobearmhelper.exe is missing. Check the 'AcroRead.msi' with shows of Orca MSI Editor: no input files for adobearmhelper.exe table.

    Install the AdbeRdr1012_en_US.exe giving the version 10.1.0.

    What's wrong?

    I downloaded the MSI package for reader 10.1.0 of:

    FTP://FTP.Adobe.com/pub/Adobe/Reader/win/10.x/10.1.0/en_US/

    and 10.1.2 update of:

    FTP://FTP.Adobe.com/pub/Adobe/Reader/win/10.x/10.1.2/Misc/

    Integrate and install 10.1.1 in 10.1.0 works fine without errors.

    Unfortunately, an update of 10.1.1 10.1.2 stops with an error and does not work.

    Is anyone know about problems with 10.1.2?

    Thanks for your help.

    Concerning

    Johannes

    Please use the correct way to create the AIP as described below. The agreement in principle for the full drive (i.e. AdbeRdr1010_en_US.msi) must be created as a transaction separate, followed by the update of the AIP created with the last update patch (i.e. AdbeRdrUpd1012.msp).

    Please visit kb2.adobe.com/cps/837/cpsid_83709/attachments/Acrobat_Enterprise_Administration.pdf for more information on the same.

    1. msiexec /a AdbeRdr1010_en_US.msi

    (When you are prompted to enter an installation location a location appropriate disk space. say C:\AIP)

    2 msiexec /a C:\AIP\AdbeRdr1010_en_US.msi /p AdbeRdrUpd1012.msp

    This will ensure that all new files added as part of a new update will be automatically incorporated in the AIP created.

    Hope this will solve your problem and save you the trouble of having to remove the entry from Orca explicitly.

  • What settings can I change my captivate program so that when a user does the program into an LMS they are marked as being completed when they hit a specific slide (not a number of slides) or the percentage of slides

    What settings can I change my captivate program so that when a user does the program into an LMS they are marked as being completed when they hit a specific slide (not a number of slides) or the percentage of slides

    I have duplicate slides that the user can jump. When they do the program is marked as progress when really, they have seen everything but technically not each slide.

    I wish that the LMS to makr as complete when they consult the last slide so that they are marked as being completed independently to know if they jumped the previous slides.

    Thank you. In fact, I managed to find a solution that does not require the user to press the button! You can add an action to a slide itself using Javascript execution on success. In the Script window, you add that scorm_setcompleted() and that tell of the SGA to mark the complete project on enter on this slide. So that's what to do if someone reads this

  • Disk utility says Everything is Fine, when it's not

    I am trying to understand what the point of disk utility. I checked (several times) my boot drive (SSD) and a second internal HARD disk, disk utility says it all goes well and nothing in need of repair. Meanwhile, I can say drives are certainly * not * ok since I get poor system performance, and the HARD disk is sprayed randomly when I access/copy some files.

    I went and got the SMART utility and Disk Warrior, SMART utility written my boot drive is FAILING and my HARD drive has FAILED.

    I am now under DW on it, but I'm pretty annoyed that utility disk is essentially useless to see if there are problems with the discs...

    Disk utility and disk warrior can only repair the files in the directory, they are unable to repair a disk that is physically / mechanically failing.

    But I can advise you that your eMachine is capable of running Windows 2000 and Windows XP.

    http://www.eMachines.com/EC/en/us/content/drivers.html

    Put your model number in the link above > then search under operating system, provided drivers

    @@@@@@@@@@@@@@@@@@@@@@

    Depends on hardware configuration required on later operating systems, and also find out if the manufacturer of the laptop computer is supported and provides drivers for operating systems later as to whether it is possible or feasible to upgrade or not.

    There is no update free from XP to Vista, 7, 8.1, or 10.

    Forget Vista as support extended for Vista SP2 will end April 2017.

    Follow these steps before you buy Windows 7; Windows 7 SP1 to support extended to January 14, 2020.

    Microsoft sells more than 7; Try Amazon.com.

    Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.

    If this is not available, Windows 7 will not properly work for you.

    Run the "Windows 7 Upgrade Advisor.

    Check if your specifications are compatible for Windows 7:

    Follow these steps before buying and upgrading (new installation) of Windows 8.1; extended support ends on January 10, 2023.

    If this is not available, Windows 8.1 not install and work properly for you.

    There is a lot of information in this first link from Microsoft:

    Download and run the Windows Upgrade Assistant 8.1 of to see if your machine is compatible Windows 8.1 and read the update for Windows 8.1: FAQ here

    So Don t worry, there s nothing unusual.

    Check the boot settings Configuration option / Quiet Boot-> disabled or something like that.
