I tried 9.2b on my XP Service Pack 3 machine and found that I could not used the wire in schematic.
I downloaded Microsoft Visual C++ 32 bit which gave me vc_redist.x86.exe
After I ran that 9.3b worked fine.
This is the 2nd machine I have loaded fritzing onto the other has Win 10 and it gave me all sorts of grief before I could load that as well.
I agree with the previous posters that there are still heaps of people using XP, I know in my case this is what I used for my hobby as the family won't touch it because it is old.
