I solved this by installing PERL 32bit and changing the "setup-stratagems" for a "Weidu 32bit .exe". Install the PERL, go to the SCS .ini and set the "use_perl_natively=0" to "use_perl_natively=1" . Here goes a way that worked for me:
1 - Install Perl 32 bits and then restart your computer (don't know if i can post links here, but i recommend the Padre Perl)
2 - Go to the stratagems.ini and change the line "use_perl_natively=0" to "use_perl_natively=1"
3 - Download the most recent version of the Weidu and get the 86x .exe
4 - Rename the 32bit Weidu with "setup-stratagems.exe" and put it where the 64bit .exe was before you delete it
5- Install it and have fun!
I hope it works for you, my dude!
