Cure for missing msvcr70.dll and mscoree.dll
By Charles L. Smart

Many users who install the current build of the Microsoft.Net SDK complain that the C# compiler does not work and C# executables will not run. Error messages note that msvcr70.dll and mscoree.dll, respectively, are missing from their system directories.

Here is the cure. Uninstall the samples and the sdk. Then restart the computer in safe mode. These are several ways to do this. The old way still works: hold down the F8 key during startup until the computer starts beeping. You will be presented with a list, select 3 - Safe Mode. If instead you see the desktop, you waited too long, try again.

Browse to the big Setup.exe file that contains the sdk. Reinstall the Microsoft.Net SDK.

The files msvcr70.dll and mscoree.dll are now in your system folder.

Restart the computer in Normal mode. The csc.exe compiler will work, and c# exe's will run.
