Windows 10: Error Message when booting Firefox.

When ever I Boot Firefox, I get the following error: cannot find WindowsApps\Microsoft549981.C3F5F10_2.2010.7621.0_x64.

What is this error and how do I dix it.

Error Message when updating from Win-7 to Won-10

Bree
I followed your suggestions (2nd Aug 19) for installing Win-10. Made the bootable flash drive successfully through the media creation tool. But when I attempted to upgrade and activate to Win-10 (64 bit) from within Win-7 (Pro-32 bit), I got the following error message:

Error # OxC1900101-Ox20017. " The installation failed in the SAFE_OS phase with an error during BOOT operation"

I read the diagnostics under this error number and carried out the proposed fixes, i.e. update Win-7, uninstall Malwarebyte antivirus, disconnect all external hardware, e.g. printer, scanner, external hard drives. I then tried to repeat the steps to do the upgrade through the Win-10 bootable flash drive as before. Got the same error message.
Appreciate any further comments and suggestions as to (a) what does a failure in the SAFE_OS during boot operation mean, (b) what can I do to solve it. Is this anything to do with the hardware in my computer? I listed these in my first posting above.
Thanks for any help

 

FireFox


Hi:

In addition to the great advice already offered....

...Most problems with Firefox originate in the user's profile, not in the program itself.

A specific suggestion for the issue you report:

Firefox - Profile in Use

Then, there is a logical sequence for Firefox diagnostics, which (as already suggested) generally starts with Mozilla Safe Mode (not to be confused with Windows Safe Mode):

Firefox - Standard Diagnostic
or
Fix slowness, crashing, error messages and other problems

Resetting Firefox (as already suggested) is certainly a reasonable option, but there are other, less "destructive" steps one might consider first.
There are also more drastic steps, such as creating a new profile. This is sometimes the best way to get back up and running, if the existing profile is highly corrupted.

Please let us know if you need more help.

Thanks,
MM

 

Windows Update Error Message 0x80070543


Ya Ya Ya, there's over a hundred threads like this, ...

Anyway, started getting this error message a few days ago, and done a lot of searching on this error message, apparently it's not, uncommon.

In particular, the (currently) 4 updates that are being affected are:

• Update for Windows 10 Version 1511 (KB3173428) - Error 0x80070543
• Security Update for Windows 10 Version 1511 (KB3172729) - Error 0x80070543
• Security Update for Adobe Flash Player for Windows 10 Version 1511 (KB3174060) - Error 0x80070543
• Cumulative Update for Windows 10 Version 1511 (KB3176493) - Error 0x80070543

The actions I've taken to date are:

1. Uninstalled firewall program (comodo)
2. Uninstalled anti-virus (Avast)
3. Reset the windows update catalog on local machine.

So the above errors are with the above done.

What other steps should I be taking to resolve the issue?

Below is notations for when I actually add to this thread.

1. Attempted to use the troubleshooter, no dice.
