The installation for FF 3.6.9 update keeps saying "Your computer must be restarted to complete a previous upgrade of FF" EVEN after I restarted it, it still said the samething.

When I click on the FF setup icon on my desktop, I only get as far as being able to select "Standard" or "Cutsom" Setup then a box pops up saying "Your computer must be restarted" and everything.
I've Have tried restarting my computer SERVERAL times, Reinstalling the setup, and looking in Task Manager for "firefox.exe"... nothing was there.
I also tried to uninstall the setup but I got that same message, so I can't uninstall it either.
Any suggestions at all??
I'm running Windows Vista if that helps any.
Thank You

It should not be necessary to reboot the computer to complete an update.<br />
If a reboot is needed then that usually means that some (security) software is blocking files or you need elevated (UAC) permissions to make changes to files or registry keys.<br />
Run the Firefox program once as Administrator (right-click: Run as Administrator).<br />
If that doesn't solve the problem then remove the Firefox program folder to do a clean reinstall.<br />

  • After downloading an update, firefox says "your computer must be restarted to complete a previous upgrade of firefox. do you want to reboot now" and will not start.

    Firefox will not start, or allow windows xp to uninstall the program. When I attempt to start the program, firefox says "your computer must be restarted to complete a previous upgrade of firefox. do you want to reboot now? It gives the same message after rebooting, and will not start, or uninstall. I also downloaded it again, same thing.

    It is probably because you are not properly closing Firefox. Restarting your system would make sure that Firefox had terminated, but you do not have to do that.
    To properly close Firefox on Windows systems, use
    :File > Exit or "Firefox:" button > Exit
    When you get the message "Firefox is already running" it is too late, and you must force termination of Firefox through the Windows Task Manager before restarting Firefox. Windows 7 has a keyboard shortcut to save you a step "Ctrl+Shift+Esc" then on "Processes" tab, select "firefox.exe" and use the "End Process" button. More thorough would be to right-click on the "firefox.exec" and choose "End Process Tree".
    You would find firefox.exe in a Mozilla folder in your program files, but y0u would not want to delete it there, you would need to use the Control Panel which you have already identified and do it from there -- but generally you would not need to do that, and there is nothing in what you have posted to indicate that you should. But if you did do that, then don't let the install start Firefox for you as you would want to use you existing desktop icon or method of starting Firefox, and should decline having Firefox install start Firefox for you. When the install starts then invoke Firefox in your normal manner. This should eliminate problems of creating a new profile rather than using your old profile.

  • I cant install an update to Firefox and cant remove the old version because a "Setup" pop up window "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?" appears, reboots change nothing. What should I do?

    A friend said she downloaded an update to Firefox (a version of 6, I believe) but didn't install the update, but the desktop icon was gone. The only way to launch Firefox was from the Programs folder. When clicking on the Firefox file, a "Setup" pop up window appeared stating "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?" Clicking "No" does not launch Firefox and clicking "Yes" reboots the computer, but nothing changes after restart and the same series of events keeps re-occurring. When clicking on the safe mode file, Firefox was launched. I went to "Add/Remove Programs" and found Mozilla Firefox 3.6.3. When attempting to remove the program, the same reboot "Setup" pop up appears, and the same non-results as previously described, persisted. I deleted all Firefox files and deleted the update set up .exe files. I again tried to remove the Firefox 3.6.3 program, with the same outcome as the previous attempt(s). I went to the Firefox website and downloaded the updated Firefox 7.0.1 set up .exe file, saved and ran it. When I reached the Setup Wizard page that prompts a "Standard" or "Custom" installation, I clicked on Standard and the same reboot pop up window appeared, again with no change after the reboot. So I have a Program installed (Firefox 3.6.3) with no files, and which can not be removed, an executed update/download .exe for Firefox 7.0.1 that can not be completely installed due to the failure to update by reboot problem. I'm out of ideas on how to try to resolve these problems. Any help would be greatly appreciated! Thank you

    Try a clean reinstall.
    * Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 7.0.x: http://www.mozilla.com/en-US/firefox/all.html
    * Uninstall your current Firefox version.
    * Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
    * Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    * It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

  • I tried to upgrade to Firefox 4.0. I keep getting error message"Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now." I check yes and it reboots, but keeps giving the same error message.

    I tried to sync Firefox mobile to my PC. Then I tried to upgrade to Firefox 4.0, which was a mistake, because I already had 4.0. I checked yes to install it again. Then I tried to uninstall and reinstall 4.0. That is when I started getting the error message.

    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer)
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
             3. MacBook Pro (Mid/Late 2007 or newer)
             4. MacBook Air (Late 2008 or newer)
             5. Mac mini (Early 2009 or newer)
             6. Mac Pro (Early 2008 or newer)
             7. Xserve (Early 2009)
         Are my applications compatible?
             See App Compatibility Table - RoaringApps.
         Am I eligible for the free upgrade?
             See Apple - Free OS X Mountain Lion upgrade Program.

  • Does the most recent OS X v10.6 update slow down your computer?

    When I first upgraded to Snow Leopard, it felt like Christmas: I got disk space back and my Mac seemed faster and more responsive.
    But after I installed the latest updates (I believe it was OS X v10.6.2 and a firmware upgrade), things have not been so rosy:
    - there is a noticeable delay when I modify the volume via keyboard keys, this used to instantaneous, now it's like a 1 second lag
    - switching applications takes longer, balking at the animation of switching between spaces
    - apps in Fusion jam up much more frequently
    As far as I can tell, my usage patterns haven't changed at all, and I really did start noticing it from my first use of new updates.
    Is anyone else experiencing something similar? I'm not too sure how to diagnose and fix this. It's too bad, because I was really enjoying the performance improvements from Snow Leopard, and now the responsiveness benefit seems gone.

    Here are some fixes for general slowness that have worked for others. Ignore any you already have tried and any you don't want to try. Try the possible fixes in the order you prefer.
    1. If you are running iAntivirus, then uninstall it.
    2. Try [resetting your PRAM/NVRAM|http://support.apple.com/kb/HT1379?viewlocale=en_US]. If everything isn't fixed, then follow the [steps here including resetting your SMC if necessary|http://support.apple.com/kb/HT1543].
    3. Look in User > Library > StartupItems and in System > Library > StartupItems. Move whatever you find in them to the desktop to see if your problem is resolved. You can move whatever you want back one at a time to test which, if any, is your problem.
    4. Use [Preferential Treatment|http://www.versiontracker.com/dyn/moreinfo/macosx/22790] to repair your user preferences.
    5.
    a. Create a new user
    b. Test apps to see that they work with no crashing.
    c. Drag your data and other needed things (e.g., mail) (not your whole home folder) into their proper places in your new user home folder. Use [this guide|http://discussions.apple.com/message.jspa?messageID=6185507] to know what to drag.
    d. Re-enter your app preferences if you are going to keep using the new user.
    e. If you want to use the old user name, then delete the old account; recreate it; and move everything back to the original locations.
    f. You will need to fix the permissions, app settings, etc.
    6. Go back to 10.6. You can do so simply by reinstalling Snow over Snow as in doing an upgrade install.
    7. Reinstall .6.1 and .6.2 using [only the combo updater|http://support.apple.com/kb/DL959].

  • OBIEE10g: Even after changing NQSConfig.INI it still loads the old rpd.

    New rpd name has been updated in NQSConfig.INI file and the services have been restarted manually. Still in the presentation services, i get the old RPD.
    The log file of both the NQServer.log and <NewRPD>.rpd.Log says that new rpd has been loaded.
    Is there anything that I am missing? Is there any way to save the new RPD directly as Online mode?
    I am using OBIEE 10g as a standalone on Windows xp.
    Thanks,

    The rpd doesnt come up in the list of available Online rpd's.
    I did check the log file again (changing the rpd name), it shows as loaded and also the subject area under it.
    Still stuck with this issue.

  • If i update my iphone to os 5 when it comes out will it lock my phone even after i have had it unlocked by the network?, If i update my iphone to os 5 when it comes out will it lock my phone even after i have had it unlocked by the network?

    Hi
    I have an iphone 3gs. It was locked to Vodafone but have got them to unlock thru itunes so i can use my 3 sim card
    I have heard that if you update the iphone software it can lock it back to the network.
    Can you let me know if its just if you jailbreak your iphone or for even if my unlock was autherized.
    As i want to get the new os5 update when it comes out.
    Thanks in advanced
    Jon

    I know I answered you before on this but can't find the thread. Guess you didn't like my answer. Your phone was illegally hacked to unlock it and when you updated the phone it relocked it back to the original carrier. This made the sim you had in the phone useless and therefore it cannot activate the phone. Nothing can be done in these forums to help you fix your problem as it is against the TOS to discuss illegal unlocking or jailbreaking the phone.
