#37 64bit dll

[Anonymous]

Am looking for 64 bit library (.lib) for my Visual studio 2010 solution. We have a linker error while referencing the 32 bit library,
error LNK2019: unresolved external symbol Wiz_SingleEntryUnzip referenced in function "int __cdecl ExtractZipFile(struct HINSTANCE__ * const,struct HWND__ * const,wchar_t *,int,char *)" (?ExtractZipFile@@YAHQEAUHINSTANCE__@@QEAUHWND__@@PEA_WHPEAD@Z)

i presume we cannot use this library, i need to know the steps to build or obtain a 64 bit version of the same
