I-Firefox Isithangami Sokwesekwa

Hi, I was trying to install MYSQL but unfortunately its failed because I am using XAMPP. SO I cancelled the installations and removed all the SQL installed file which were installed in that mean time when installing SQL. After I restart my windows and try to open firefox and showing exactly same error popup and then I uninstall firefox and trying to resinstall it but I cannot. There showing that error notice. I also tried to renamed "prefs.js" but its not solved. Would kindly give me any suggestion or do you kindly solve it remotely please. I love the browser and using it since 2012. Thanks in advance

I don't know, suddenly it showed me VCRUNTIME140_1.dll missing and reinstall the browser. i tried it, nothing happened, then i refreshed the browser, nothing happened. tell me what to do.

Firefox worked fine for me until last week. I tried to install a new copy and I get the following message -

THE CODE EXECUTION CANNOT PROCEED BECAUSE VCRUNTIME140_1.DLL WAS NOT FOUND. REINSTALLING THE PROGRAM MAY FIX THE PROBLEM.

No matter what I do, I cannot get this to install.

It appears to install but when I open Firefox and try to navigate to a website it is dead in the water. Will not connect to internet!

Please help!

Hello,

when I updated the Windows 10 to it's latest version, all websites stopped showing in the Firefox browser. When I try to type a url and press enter, nothing is showing up (https://imgur.com/13i6kNc). Extensions are also not showing up (https://imgur.com/gfVqWap). Not even Firefox settings (https://imgur.com/xO0D2cJ). Other browsers are working normally (I tried Internet Explorer 11, Google Chrome 84 and Opera 70).

Thank you for taking your time to read this.

my browser has suddenly stopped loading anything whatsoever. unable to even go to options, as nothing happens when i try to press it. clicking on bookmarks lead to nothing happening.

i am connected and can use chrome all fine.

tried using safe mode/refreshing, made no difference

heres a YT video showing what happens (essentially nothing when i use firefox), and how chrome performs

never had this issue before

thanks

So my Firefox became completely unusable this morning I tried to refresh then reinstall I've had Firefox on this system for 2 years up until today I had as my default for 6 months at this point. I even installed a nightly build to see if that would work no luck if anyone could help me that would be greatly appreciated I really dont wanna go to a chromium browser I have Windows 10 20H2 for my os if anyone wants to know I also use manjaro Linux and Firefox works fine in that os.

I have a customer who is unable to browse to any websites after version 81.0.2 was installed. They are also unable to open Options and other Menu items. Only Toolbar Menu item that worked was Help > About. I have tried using Firefox in Safe Mode, I have refreshed Firefox, and I have renamed the AppData > Roaming > Mozilla folder forcing it to create a brand new user profile. The only security programs running are Windows Defender. Chrome and Edge work fine, so customer will use one of those until Firefox is fixed.

I was cleaning out my hard drive and deleting old installs of Microsoft Visual Studio Redistributable packages, and I almost certainly deleted the one that Firefox relies on.

I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."

I uninstalled, following the clean install directions, and deleting the "Program Files/Mozilla Firefox/" directory.

Then, I ran the Firefox Installer, newly downloaded, and when running it, it gives the same error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." Selecting "Restore Defaults" has no effect either way. The installer then appears to complete in the background, and the Firefox directory is created, along with the executable.

When I run Firefox.exe, it seems to load the program, but any address I type in fails to begin loading. This includes websites (www.google.com) and help/utility pages (about:config). I'm therefore unable to change any settings within Firefox.

I then tried re-installing the "Visual C++ 2008" and "Visual C++ 2015-2019" packages in an attempt to restore that DLL, but that had no effect after repeating the same steps above (clean uninstall, re-install). Which VC++ Redist Package should I be re-installing? Ideally, I should be able to just get a copy of VCRUNTIME140_1.dll and place it where Firefox is looking for it.

I tried to install the Snapchat filters after watching "Cat Lawyer" - and I got a VC++ Runtime error. Firefox stopped loading too with the same error.

I removed the Snapchat filters app; repaired the VC++ Runtime error in add/remove programs - and now I see the symptoms as follows:

1. Launch Firefox from FF Icon.

    a) Bookmark clicks do nothing.  
    b) Type in a URL and nothing happens.

2. Launch Firefox from a ZOOM meeting link (and presumably other links) works - the page loads. And , once I have done that , the firefox browser works normally.

I can probably just uninstall/reinstall - but if anyone knows how to solve this I'd rather not lose all my saved pwd and history.

Running: MS Surface, Windows 10.

I am trying to re-install Firefox but seems never to complete the installation. It does not open any websites and does not appear to connect to the internet. Also, I receive a message that the file VCRUNTIME_1.dll is missing; however, when attempting to download the file, it tells me the file is already installed.

I uninstalled Libre Office and it apparently uninstalled the VCRUNTIME140_1.dll file s part of its uninstall process. From this point Firefox would open but would not connect to the Internet, either by clicking one of the links in the toolbar or typing the address directly. I have tried all the solutions I can find on the support pages, ranging from attempting to copy the file from another location to re-installing Visual C++ from the Microsoft website, both the 64 bit and the x86 versions. Having found and installed the latest version of Visual C++ I now get the error message "The procedure entry point _CxxFramehandler4 could not be located in the dynamic link library C\WINDOWS\SYSTEM32\MSVCP140.dll" at the edn of the installation process, and of course Firefox has not installed. Any suggestions for a way forward?

When opening Firefox, a window opens with menus and toolbars visible, but nothing loads or opens up when navigating the application. No websites are loading, no menus are opening such as options or add-ons, and not even the mozilla landing page is loading. I have tried doing a "Refresh". I have tried doing a clean reinstall. I have run virus scans to see if malware was preventing it from opening websites. I am having no issues with other browsers, just Mozilla Firefox. I am unsure what to do if even a Firefox reinstall is not working. The application wont even let me enable/disable add ons to see if that may be causing the problem.

web pages don't display but address is shown at tabs, can't see options but other menu options seem to be okay. I uninstalled and erased all related data (I could find) multiple times and reinstalled multiple times but problem remains. I tried refresh, safe mode, etc. At installation I get error VCRUNTIME140_1.dll not found, a susequent installation finishes without errors. I am sending this from another system because I can't use the problem unit for this post. The problem system is similar to this one. I am puzzled and seek help.

How do I fix this? Firefox won't start (it did a few days ago).

Version 87 running on Windows 10.

Error Msg: The code execution cannot proceed because VCRUNTIME140_1.dll was not found.

There is a file: VCRUNTIME140.dll in the C:\Program Files\Mozilla Firefox folder.

I reinstalled Firefox but that didn't help.

I have very much came to depend on Firefox. I've tried everything mentioned to users with same problem. Even Passwords and Settings have white windows (no text or anything else showing. When I reinstall Firefox I get vcruntime140_1.dll error. How can I fix it? I have the latest update.

While writing this I went back to double check the vcruntime140_1.dll install. I found it wasn't on the main Mozilla Directory - so I copied it. And now Firefox works! The file came from https://www.dll-files.com/. I don't need any further assistance.

Just leaving this as a record for others who may be having a hard time.

Thanks Mozilla for all you do!

I am unable to open my Firefox on my computer because I receive a message saying that my computer cannot find the following file: vcruntime140_1.dll. I have tried uninstalling Firefox, and the reinstalling Firefox. This did not solve the missing file problem. I have tried re-installing Firefox. This did not solve the problem. The file is still missing. When I click on my Firefox App, all I get is a blank screen. I am unable to use Firefox. This computer uses Windows 10 with a 64 bit. I have several other computers, with Firefox installed, and I do not have this problem on any other computers using either Windows 10, Windows XP, or with a recent version of Linux. What procedure can I follow to restore this missing file to this computer? Your help would be greatly appreciated. I have some knowledge of computers, but I lack technical knowledge. Any help you can give will be deeply appreciated. Thank you

I tried Mozilla VPN but it would never connect. So I uninstalled and cancelled. Then I got a persistent vcruntime140.dll not found error. I uninstalled iTunes and legacy Microsoft Visual Suite apps. Now nothing will load. Not about pages. Not password pages. Not websites. Nothing. Have uninstalled and refreshed Firefox multiple times. Have restarted PC multiple times. Have turned off firewall and virus protection. Nothing works. nothing loads. Thanks for your thoughts!

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

Installation in German language under W10 Home 64bit. VCRUNTIME140_1.dll not found, installation interrupted. Firefox seems to be installed, but totally unresponsive (no files, no websites, not even parameters). Any known measures? Thanks!
