PPSSPP x64 build on Windows 7 64bit

[KabooZ18]

my xinput9_1_0 (64bit) was corrupt I think didn't work when I copied it to the ppsspp folder tried to delete it but the owner changed to trusted installer??
and after I killed it with fire and tried to install it with DX runtime june 2010 (standalone) it just didn't so I manually extracted it and voilá that worked (still needed to copy it to the ppsspp folder though since it tried to use the 32bit ver -.-)

I guess there's something very wrong in my system but I'm not entirely sure where...
if someone has some ideas please share^^ (I think that should be still in the scope of this thread, though I'm not sure)
