Cannot Link examples

Help please!
Cannot Link any example (such as Helloworld, Bmpmanip) on Visual C++ 6.0
It looks like:
NMAKE : fatal error U1077: 'dumpbin' : return code '0x1'
Stop.
if exist "\Symbian\6.1\Series60\EPOC32\BUILD\SYMBIAN\6.1\SERIES60\SERIES60EX\BMPMANIP\GROUP\BMPMANIP\WINS\UDEB\BMPMANIP.exp" del "\Symbian\6.1\Series60\EPOC32\BUILD\SYMBIAN\6.1\SERIES60\SERIES60EX\BMPMANIP\GROUP\BMPMANIP\WINS\UDEB\BMPMANIP.exp"
Stopped the build by removing the export object,
if present, because the pre-link stage failed
