msvcr80.dll missing

This is Windows 10 Pro with Office 2007.

Suddenly Excel won't run.  msvcr80.dll is missing.

Since this is a remote workstation, I'd like to fix it without having to insert a DVD to reinstall Office.
Is there another way?

I've run DISM and sfc with no change.

1. Do you just installed any third party add-ins?
2. Tried to run excel in safe mode, and then try to open these files using the ‘Open’ option

If this works then you will need to disable the third party com or get the update.
James GarlandIT Technician/ConsultantCommented:
Another option could be to locate the specific msvcr80.dll from a computer with Office 2007 installed, and copy it to the remote workstation.

If you can get someone to insert the DVD at the other end, it should take no more than 10 minutes to reinstall Office 2007 to correct the problem. That is what I would do.

You can always upload the DVD of Office as an iso and mount it using something like WinCDEmu

Good idea. Windows 10 can mount ISOs natively

I didn't noticed it was Windows 10...i thought it was Win7

Thanks for the replies.

OK.  I do have an Office 2007 Ultimate DVD here at the office.  I looked into it and didn't see the needed file.
I could transfer the file from here if I could find it.

As before, I don't want to use local help.  Part of the reason for that is to be better at remote things in general.  
In this case, dealing with DVD file contents would be one of those.

I probably can find another computer with the necessary file as well.
I looked on another computer with Office 2007 and didn't find the file there in Windows\system32.
But, by searching the entire drive I found a number of copies inside HP printer setups.
This is very puzzling....

Convert the DVD to ISO and copy to remote computer and do a repair install of Office
Fred MarshallPrincipalAuthor Commented:
It did not work to use one of the msvcr80.dll files copied into Windows\system32.
The error generated was different though.
This time it said that a program tried to open the C++ (something) inappropriately.
So, I got rid of that and am doing an extra virus scan.

In the mean time, I'm creating an .ISO

(*&(_^*)%!!  I wrote a comment and then closed the question.  My comment was dropped.  Sorry.

I can't confirm that the mounted .ISO would have worked under different circumstances.  It did not.  Even when i went on site it failed as if being mounted were an issue.  In the end I used a bare DVD.

Still, the answers I received were along the lines of discovery that I set out to do.

Thanks all!
