Program can't start because WLDCore.dll missing.
There are a number of files used by more than one of the Windows Live programs and services, so they're stored together in shared folders. If one of the programs can't find one of the common files, it's often because there's a problem with the PATH system variable, which should contain the paths to the shared folders. On a 64-bit system, that would be:
| C:\Program Files\Common Files\Microsoft Shared\Windows Live;<br><br><br>C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;<br><br><br>C:\Program Files (x86)\Windows Live\Shared; |
|---|
To check the PATH, press Windows key + R, type
cmd and press Enter to open a command window. Type path into the window and press Enter, then look for the entries shown in the box above.
