Alain,

It looks like VS cannot find the regex library.
You must tell VS where to find it.
Project -> Properties -> Linker -> General and additional libraries
directories
Also you must add the regex library
Project -> Properties -> Linker -> Input.

Last but not least, make sure that your lib is 64 bits.
Cheers
