LibreOffice on Windows 7 with Office 2016 installed

Sorry if this has been covered but I am a new to LibreOffice and this site was installing on Windows 7 that has Office 2016 installed . My question has to do with getting some information about what existing Windows files LibreOffice replaces - can someone provide a link to where that could be found?

As an example, while installing LibreOffice there was a prompt stating that "some files that need to be updated are currently in use" and named windows explorer, vnc and displayfusion as apps. Why would LibreOffice need to update files from these apps?

I'm asking because I'd like to know what the application is installing that may be affected by Windows patches that are regularly installed here -

Thank you

LibreOffice includes only one "Windows" component: MSVCRT (C runtime libraries). It also installs some fonts (which is what multiple applications might be using, and having older versions of which might give the warning in case some fonts are in use). It installs some shell extensions. But the magic behind the MSI deciding which components are blocked by which running programs is a mystery. At least at some point in history, it used window titles to detect "programs blocking installations".

Hi Mike Thank you for the information. I ran process explorer to see which exe's this dll loaded for and I got 68 different apps listed. I also went on a test machine and removed the msvcrt.dll and Windows7 wouldn't boot afterwards. I am not aware of what this dll does but it seems to be a core dll. Is there a link where I can find out why this dll is needed by LibreOffice and what changes to the original exist...Thanks again for your answer

It is needed because we build LibreOffice for Windows using MS Visual Studio linking to the MSVCRT dynamically. The "what changes to the original exist" is a question to MS, which maintains the libraries.
