This time it become worse even more .dll issues...
boost_system-vc120-mt-1_55.dll
libxml2.dll
libcurl.dll
& libeay.dll
there is no more issues with the previous 2 dlls for some reason...
If anyone has the same issue, i found a solution!
I do not know why or how, but compiling the projects after the new installation/upgrade works for me.
