MSvcr90.dll

I recently upgraded from Win 7 to 10 and have one problem after another. The specific one I am writing about is the fact that I cannot now get into my excel spreadsheets. Keeps coming back that I am missing MSvcr90.dll. However, how is it that I can open windows without a problem. Also I could not open Power Point. What a mess. Please help me out with this. I need to get to excel soon.. I am running microsoft office home & business 2010 x64 on a dell Optiplex 790 (old timer).
Thanks

Try "repair" installing Office from your install DVD or Media. That's worked for me when this has happened in the past.

You need to use an installer that it the exact same version you used, and I don't know if this will work for those versions that mount a virtual disk, like the "1-click" Office Versions. But the installer resides on a mounted virtual drive, so I don't see what would prevent anyone from running the repair from that.

Just find the "setup.exe" file for whatever version you have, right click on it and you will see a "repair" option, choose that, and all of your missing files should be replaced.

The only other thing you can try is google the DLL file and see if you can find a version of it that will work for your system, but I doubt if the DLL sites have many Windows 10 file versions yet.

Might check this page:

Ah, there is a security update for Excel that seem to be causing this, try removing that first.

I deleted every update specific to excel but it did not work. What now?

MSVCR90.DLL is part of Visual C++ redistributable. Normally when you install a program the correct version should be installed along with it automatically. You could uninstall and re-install Office and that should fix it.

Alternatively you could check you have the same installed as me (as I have Office 2010 and not much else). You should have these 4 (although perhaps one is due to me installing something else). If you are missing any you can download them from MS. They are small and note, not cumulative so 2012 version does not include 2010.

For me Excel 2010 works fine with all latest updates.

halasz beat me to the punch, you need to install (or reinstall) the redistributables. Personally I make it a habit to reinstall all of them each time I reload windows. You can find download links for all 2005-2013 redistributables here:

And if you so happen to end up needing the 2015 redistributable just google it and grab it from the microsoft download page
