• HPPIW. EXE does not solve the problem with the installation of the complete software for 8500 A909g

  Waterboy71 - sorry for a new position, but the forum is read-only (?) so I can't respond to your response to my problem with the installation of the driver/software 8500 A909g.  By your answer on 5/19, I downloaded HPPIW. EXE and it ran.  It detects my wireless printer, but it tells me that "the selected printer is not supported by this wizard."  Is there another thing I can do to install the software so that I can scan and fax from my Windows laptop 8.1?

  Hello
  If please try following the steps below and check if this can solve the problem:

  1 open the Mcafee Virus and Spyware Protection software you are interested in, click on calendar and perform analyses. Click analysis in real time, and then click stop. Select until I restart the PC and confirm by clicking the button turn off.
  2. open the dialog box run by clicking on the Windows key and the R key on your keyboard. Type %windir%, and then click OK.
  3. type hpoins*.dat in the search bar at top, if there is that no result rename the extention in old instead of dat. (e.g. hpoins1.old)
  4. type hpwins*.dat in the search bar at top, if there is that no result rename the extention in old instead of dat. (e.g. hpwins1.old)
  5. start the Run dialog box by clicking the Windows key and the R key on your keyboard. Type MSIEXEC /Unregister. in the Run dialog box and click OK.
  6. launch the Run dialog box by clicking the Windows key and the R key on your keyboard. Type MSIEXEC/REGSERVER in the Run dialog box and click OK.
  7. run the installation file and check all difference.

• Could not find the problem with the sound and speakers

  Hi, I have a Pavilion dv7 with windows 7 and there is the sound of the computer, commissioning, but if I try to watch a video or listen to music online there is no sound. Also if I open Itunes, and I press play on a song of the song does not play. I tried using media player but it says it can not play either.

  Hello

  Try the following.

  Download IDT Audio Installer on the link below and save it in your downloads folder.

  http://ftp.HP.com/pub/SoftPaq/sp58001-58500/sp58226.exe

  One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.

  When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

  Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

  Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  'Speakers and headphones' left click once to highlight, and then click the Set Default button - check if you now audio.

• Why can't I make a new tab in Firefox 3.6.16 manually? I have Windows 7 and did not have the problem with other versions of Firefox.

  My question says it all. I click on the new tab button and nothing opens. By clicking on the links will open a new tab, if necessary, or using "Open in new tab" seems to work very well.

  Uninstall the toolbar Ask and it should work again. There is a compatibility issue with the Ask and Firefox toolbar that prevents the opening of new tabs.

  There are a few places to check for the Ask toolbar:

  • Check the control panel Windows for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
  • Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

  I don't have time right now to study exhaustively, but for me his vomit ORA-00942 table or view does not exist on this line:

      SELECT sql_id, child_number into tmp_sql_id, tmp_child_number
           from v$sql where sql_text like sql_statement||'%' and sql_text not like '%v$sql%';
  

  I am able to select from v$ sql in normal SQL as user I am compiling as, so don't know why it's complaing.

  Anyone know if there are certain restrictions on access to the views v$ through PL/SQL?

  EDIT: http://www.dbasupport.com/forums/showthread.php?t=22299

  Access to the views of $ v seems to be through a role - try giving explicit access to it.

  As SYS, you must grant select permissions on V_$ SQL (V$ SQL is synonymous with V_$ SQL) to your owner of the procedure. Just tested on my system and it allows him to compile.

• Since the last update of Firefox, I don't see a security lock when I connect to my two web sites to secure Bank so am forced to use IE and the two banks said the problem with Firefox, not their systems.

  Since the last update of Firefox (Version 4.0.1) I do not see a security lock when I connect my two web sites to secure Bank so am forced to use Internet Explorer for internet banking. I contacted the St George Bank and the ANZ Bank and both say that the problem with Firefox, not their systems. They advise also strongly me to not perform Internet banking unless the security padlock closed is visible in the window secure. The padlock is not visible when I connect secure site of PayPal. Before the upgrade, this problem did not exist and there is no when I use IE. Firefox is my favorite browser.

• the problem with the wi - fi does not work on windows 8.1

  Hello dear forum users (sorry for the English, use a translator)

  I have a laptop HP Pavilion dv6-7055er, 8.1 Windows 64-bit

  Card Broadcom WiFi 802.11b/g/n 1 x 1 4313GN worked on windows 7, but fails on windows 8.1. Tried to find the driver on the broadcom , but not found. Device Manager indicates that the problem with a PCI device. Specifies no problems with the Wi - Fi adapter.

  What could be the cause and how to fix it? Thank you!

  It seems that your WIFI adapter is not supported by Windows 8.1

  There are a few options available.

  The first and simplest is to purchase a USB wifi adapter to plug into one of the USB ports on the laptop. I have a dual ASUS USB-AC56 band that meets the 802.11ac specification.

  The second option will be to take a look at the installed optional wifi adapters to see if they have Windows 8.1 supports, buy one to replace the Broadcom card installed with.

  Ok. The two following adapters are compatible with your laptop and Windows 8.1. They have a BIOS support.

• The problem with Windows update - automatic updates service won't start not (error 126)

  original title: the problem with Windows update

  Please help me to get Windows Update operational return.

  XP Media Center Edition, Version 2002, SP3

  Had a problem with "Generic host process for Win32 has encountered a problem and needs to close."  Follow-up of the instructions on this link:
  http://support.Microsoft.com/kb/931852

  Seems to have cleared the error message.  So far so good.

  However, now a Windows Update does not work.  Security Center Windows were told to go to control panel > system and use the Automatic Updates tab.  But, if I go to control panel > system, the Automatic Updates tab does not appear.

  I also went to the control panel > Services.  Tried to start the automatic updates service.  Received this error message: could not start the service automatic updates on Local computer.  Error 126: The specified module could not be found

  I already followed several instructions on this subject:

  In the thread above, I was following the post on 30 August.  According to Option A, I completed step 5 for the uninstallation of McAfee Security.  At this time, my network card has stopped working.  On the recommendation of the officer, I posted to the Malwarebytes forum.  The officer determined Malwarebytes that I don't have a malicious software.  I ended up posting on forum McAfee to get my network card works again.  Then I reinstalled McAfee and start to run Windows Update.

  I started with Option A, step 8 to reset Internet Explorer using http://support.microsoft.com/kb/923737.  The difficulty it has worked very well.

  Then Option A, step 9 says reset Windows Update using http://support.microsoft.com/kb/971058.  When I ran the difficulty in default or aggressive mode, I got an error message saying: he cannot start wuauserv.  The message asks me to verify that the user has privileges to take this step.  Well, I checked through user accounts who am the only one user set up on this PC and I have administrator privileges.  Help me please run this difficulty or recommend another way to get Windows Update works again.

  [1]... looks like you are saying that my system is so wet that a clean install is the (only?) way to go.

  [2] if I do a clean install, not only what I need to reinstall Windows and all my applications, I also have to reinstall the drivers... Etc. ?

  [3] I think I have the disks supplied with the PC system. Is it better to use than to use the recovery partitiion?

  [4A]... is there a possibility that some of [my data are] infected?

  [4] preventing me from simply infect the whole PC again?

  A1. Yes, and it was my recommendation in August, too.

  A2. Yes.

  A3. Only not really well using the restore Partition hidden to make the "destructive recovery" will include all drivers, etc., that have been installed at the factory.

  A4a. Yes, a real possibility.

  A4b. You run at least three 3 tests on the backup data before restoring one (1) with your installed & updated up-to-date anti-virus application (for example, Microsoft Security Essentials) and two 2 with good reputation, free online scans (e.g., ESET;) Bit Defender; Kaspersky; HouseCall; (F - Secure).

  If you have saved your data on CD/DVD, the disc scanner. If you have backed up your data to a flash drive, SD card, or another external drive AND KB971029 is installed, analyze the drive.
