    Thanks for the post. In our case, we received prerequisite errors because we did not run the install as administrator.

  2. Michael Rose says:

    prvf-3029 I keep getting this install error, and don’t know how to fix it. Using windows 7 Ultimate. 64 bit machine.

    Hi Michael
    Please try one of the solutions on this article. You can also uncheck some Oracle Installer (OUI) prerequisite checks:
    “Checking operating system requirements” … and “Checking service pack requirements” … to bypass OS prerequisite checks.

    I am using Windows 7 with elevated permissions but not admin. Is that a problem? I tried your steps but am still unable to install.


  6. Kirill Loifman says:

    Admin rights are required.

  7. SteveP says:

    PRVF-7531- can’t see node

    try: NET USE \\computername\C$

    will setup C$ for use. similar to sharing issue encountered by others.

    Hi Krill, i have tried all your solutions and it still showed the failed prerequisites. Was surprised it still failed after using the last ‘Setup.exe -ignoreSysPrereqs’ solution. Pls what else can i try.

    Specifics; Windows 7, oracle 11g 32bit.

  11. Kirill Loifman says:

    Thanks Steven for a tip.
    I’m not sure if this will work the same on Windows though.

  12. Kirill Loifman says:

    Unfortunatelly with WIndows it can be anything 🙂
    Can you please provide more details about the errors you get

  13. Wojtek says:

    In my case server service disabled
    thx !

  14. Tracy says:

    Look for a check-box options to ignore the prereq checks on right top of error dialog box , check it to tell it ignore them continue to the installation.

  15. Hector says:

    Thank you! The “run as administrator” fixed it for me.

  16. Helen Goussarova says:

    may be my post will help some poor soul

    I attempted to install 11g 32 bit client on Win XP Home edition (please do not laugh), and got the same error messages – nothing could be verified.

    I installed 10g instead, with no problem.
