Do a clean reinstall and remove the Firefox program before (re) install a new copy of the current version of Firefox.

If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

  • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

Remove the Firefox program before installation newly downloaded copy of the Firefox installer.

  • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.

  • At the start of what Firefox says "could not load XPCOM.

    My desktop is running Windows 8, which recently crashed. Since then, whenever I start, 17.1 Firefox (which is in the folder startuo) does not load, but shows an error window saying (unable to load XPCOM). Rejecting the window then allows me to start Firefox myself. I uninstalled Firefox (but not personal stuff), downloaded a new copy of Firefox 17.1 and re-installed... same thing happens.

    Just to clarify... This only happens only once, after the initial start of the desktop computer. I close the error window and everything is fine after that.

    Bright ideas please?

    What makes XPCOM reference? A missing dll file? can I find this file elsewhere and move it to the correct location?

    Many ways.

    Thanks again for all the responses.
    I now put Firefox in my 8 and restarted Windows startup folder.
    All right, Firefox (or Thunderbird) starts as it is supposed to and there is no sign of an XPCOM related error message!
    So... I have to assume that the problem was (somehow) caused by crash my Windows 8 and that (somehow), remove the Win 8 of Firefox startup folder, restart, then put Firefox in the startup folder, and then restart, has put things back where they used to be. A little strange, but I hope that the above may be useful to someone else with a similar problem in the future.
    Well cordially to all.

  • Canon MP620 install launches the error message "Could not load any file of resource".

    I reinstalled Windows XP on a fresh partition a few days previously.  I applied SP3 and all updates of windows until no updates are available.  I applied the motherboard and video drivers & s/w.  Windows updates applied an update to the CPU driver, if I'm not mistaken.  I didn't have many other things still installed at this point beyond Panda, office and a few utilities simple, affluent (Notepad ++, Total Commander, etc - things without installs pretty simple).

    When I try to install the printer driver Canon MP620 (md8l-victory-mp620-1_04 - ea24a.exe, for use on local network), after the one the switch over and half dozen clicks later software is about to install but then get the following error:

    INSTALLATION PROGRAM. EXE

    Unable to load a resource file.

    I contacted Canon support.  Not surprisingly, they said it wasn't their problem and that my system was to blame.  To be honest, I was able to run the same configuration file, without getting that error, on another machine.

    ... Any other relevant details of the _potentially_...

    I already had a problem with es.dll (do not have the details on me).  I got an error message (twice) which suggests that it might be corrupted, so I ran sfc/scannow.  After clicking on several attempts on my original Windows XP disc in the analysis, it finally finished without reporting problems or corrective action.  Never seen the error once again since.

    ... then...

    I can't find all the other tracks on the internet that take me somewhere.  I used to be quite a geek, but I think that I'm not dumber as I get older.  Without a solution, I can't use this printer.  I need to use it as both a printer and a scanner, so I would use Canon software provided.  Can anyone suggest it please what else I should try?

    Other details which may be relevant:

    -Windows XP Professional Service Pack 3 (build 2600); the system is up to date with windows updates

    -You try to run md8l-victory-mp620-1_04 - ea24a.exe (network for printer Canon MP620 multifunction driver) downloaded fromhttp://www.canon.ca/inetCA/serviceDetail?m=load&id=5&sid=27&mid=0002200452&type=D&opt=1

    -I have not found a driver for Canon in the 'Add printer' wizard standard who recognized the printer.

    Hello

    ·        What version of the XP operating system do you use? 32-bit or 64-bit?

    I suggest trying to install the printer using the wizard for adding and deleting printer and check if you are able to install the printer on the system or not.

    What Add Printer Wizard does not complete the installation of your printer

    http://support.Microsoft.com/kb/823447

    It could be that an application is in conflict with the installer. I suggest to perform a clean boot on the system, then try to load the drivers from the printer and check if the problem is resolved.

    I then restored by day sauvegardΘ installed upgrading again every day would not restart with the same message
    I tried again on Saturday you have the same problem
    I'm now ignoring the update message that is very annoying because he wants me to update daily

    The bug in question should be solved with a daily update of today. However, I agree with the recommendation to go with 31.0 once it comes out next Tuesday, or at least to use the beta versions (once per cycle) as a compromise between stability and get the latest features and updates to the platform.

  • Error. Could ' t Load XPCOM. Can't Uninstal from Windows C/P

    (a) running Mozilla Fireforx 23.0.1.4974 on a Dell laptop Studio XPS 1640 with the 64-bit of Windows Vista. I had to do a restore of the system back and since then my Mozilla Firefox is not running. I get the following:
    Part 1. "Error. Could not load XPCOM. Tried the solutions of this forum to UNINSTALL before you perform a new installation of the latest version.
    Part 2. In the Windows Vista Control Panel, Uninstal does not at all. Just a blank nothing.
    Before deleting the content & directory: C:\Program Files (x 86) \Mozilla Firefox, I noticed another directory C:\Program Files (x 86) \Firefox (99) that was created when I did a reset a few weeks ago. There is a folder on my desktop called 'Old data Firefox' which I assume icon contains my favorites, add-ins etc reset, I did it on August 18, 2013.
    Part 3. I tried the suggested search for %APPDATA%\Mozilla\Firefox\Profiles\ so that I could find, backup on a USB and a restoration after a new installation, but it returns no results. Is there an actual path I can use to locate these data? I want to retain my lastest bookmarks, modules etc. for installation of the latest charges.

    Hey Tom,

    This is probably because your project is configured to target AnyCPU and not x 86 (Measurement Studio assembled currently only support the x 86 platform).  See the help topic using Measurement Studio on 64-bit operating systems for more information.

    My e-mail program no longer works as now produces the message "could not load plugin".

    The support group at Cox Cable, my e-mail service providers, was not able to solve the problem

    Any suggestions or solutions would be greatly appreciated.

  • Flash CS5 could not load stage in memory. Your document may be damaged.

    Hi all!

    Just bought the new Flash CS5 and was eager to start my first paper. I opened a new document registered on start and then configure my basic page with only an imported graphic. Click on save and received an error message: could not load stage in memory. Your document may be damaged. When I closed and reopened the document this same error appears twice in my menu "output".

    I noticed people with many of the simular issues and don't know where to start find an answer. Any help is greatly appreciated.

    Thanks in advance,

    It's just import a graphic into your file and save the file? Since you have not done much with the file, I just would say about this one, delete it and start over. But, is - this happen every time? Try different things before you save the file, as instead of importing a graphic, draw shapes of basic with the drawing tools, and save the file.

    If the problem persists, rather strange, it's either a problem installing, or your computer may not be responding the minimum requirements to run Flash.
