Yawcam 0.7.0 won't start on Windows XP

Ok, I know Windows XP is not - cough cough - supported anymore. :D
(I noticed I opened a similar thread some years ago, too :o )

However, I have a very old notebook with Windows XP and Yawcam 0.6.2 still works, but Yawcam 0.7.0 stays frozen on the splash screen.

Running debug_start.bat I get:

0.7.0 == 0.7.0 -> 0

I've followed the procedure here: ... 528#p12472
but it doesn't work.
The problem seems to be with file dsj.dll. The last Java version to install on Windows XP is 8 Update 152.
I'd just like to know if Yawcam 0.7.0 simply doesn't work on Windows XP.
