To get wxWidgets to install with Visual C++ 2005 Express, I needed to change the linker options to set Incremental=No.
Otherwise, I was getting this Linker Error
CVTRES : fatal error CVT1100: duplicate resource. type:MANIFEST, name:1, language:0x0409
LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
