LNK 1181 error

[ixid via Digitalmars-d-ide]

I've suddenly started having this error, even after reinstalling 
DMD, Visual D and repairing Visual Studio 2013:

"Debug\euler169.obj,Debug\euler169.exe,Debug\euler169.map,user32.lib+"
kernel32.lib/NOMAP/CO/NOI/DELEXE
LINK : fatal error LNK1181: cannot open input file 
'Debug\euler169.obj,Debug\euler169.exe,Debug\euler169.map,user32.lib+'
Building Debug\euler169.exe failed!

Any idea how to fix this?
