Hi there,

I am having difficulties today. I was downloading a surveying software program and it appears to have made changes to my computer, such that it destroyed my ability to use Firefox. I have uninstalled it and tried installing it several times . . . and I get the same error coming up (see attached screen save).

Can you assist me in being able to install Firefox again.

Thank you.

So I was cleaning out my SSD of a bunch of junk files and I think I might have deleted a file Firefox needs as when I open Firefox it seems to just blank with the search bar and when I try to go to say YouTube nothing loads. So I tried to do a fresh redownload of Firefox and the installer just this error saying "The code execution cannot proceed because vcruntime140_1.dll was not found" can someone help me get Firefox working properly again?

I am having issues with activation of an existing O365 subscription. After hours working with Microsoft Office support the issue is still not resolved.

That is seemingly unrelated to Firefox, yet when trying to resolve the issue I uninstalled O365 twice, I could not open Firefox. I received the error "VCRUNTIME140_1.dll was not found". After reinstalling O365, I was able to access Firefox but all of my bookmark folders are gone.

How do I recover those bookmark folders (with hundreds of bookmarks--if they're permanently gone, it will be a significant loss). AND why would uninstalling O365 affect Firefox?

Tried to download and install the Firefox browser, 64 bit. While processing, said "cannot continue, cannot find VCRUNTIME140_1.dll. I know that I did remove the Visual C re-distributable file or from the windows system but have been trying to re-install. Downloaded and executed visual c, to no effect, did not re-install the driver or whatever Firefox is looking for during the install. At a total loss on how to re-instate the VCRUNTIME140_1.DLL so that I can use Firefox, HELP!!! P.S. the help provided on-line tells one how to re-install the driver but so "poluted" with other programs wanting you to download their programs that impossible to find the correct tools to use. Anyway, your help will be appreciated. I do like Firefox and have been enticed to use Microsoft Ecge but do not want to if I can help!

when i try to reinstall firefox 88.xx i get error that vcruntime140_.dll is running or something, and install will not finish.l HELP

About a month ago, Firefox stopped loading web pages on my Windows 10 Lenovo Flex 14-IWL computer. The UI loads without any issues. However, no pages can be loaded, including Firefox's own pages like "about:preferences" or "about:performance." I completely removed all traces of Firefox from the computer twice (using Revo Uninstaller's advanced mode), but the problem remained after each reinstallation attempt. On the second of those reinstall attempts, I checked the Console after trying to load one of those control pages and found the error messages shown in the attached screenshot. What is happening, and how can I get Firefox working again?

(Note: Since I have completely uninstalled Firefox again since taking this screenshot, there is no troubleshooting data to send.)
