CCleaner crashing newly installed XP sp2

I just installed XPpro (sp2) on a laptop that is new to me (Toshiba A75).

Everything is running fine, including Avast AV.

CC installed fine (latest version and 5.06.5219, I tried both) .

When I attempt to open CC (both manually AND with box checked immediately after install),

I immediately get the blue screen of death and this error message:

c000021a Fatal System Error

(0x7c9106c3 0x0052ec24)

I have been using the Cleaner for at least 15 years and NEVER had a problem.

I rely on the Cleaner and cant stand the thought of not cleaning up my new laptop!

HELP?!

Thanks in advance!

It doesn't really support XP SP2 without issues unless you install a fix from Microsoft, see here:

I installed the Hotfix and no longer get the BSOD, my computer now reboots when I attempt to open CC (latest version).

Is there any particular version that works well with sp2?

Maybe I will try V 4?

Version 4.0 works great!

Thanks!
