Dr.Web Security Space 8 installer causes BSOD NTOSKRNL.EXE

When starting the installer, after ~2-3 seconds, the system crashes to BSOD.

There are two assertions in debug.log which can probably indicate a problem:
in fastfat:

(drivers/filesystems/fastfat/finfo.c:1443) IRP_MJ_QUERY_INFORMATION without FCB!

and directly in ntoskrnl:

(ntoskrnl/ex/resource.c:145) EX: resource: APCs still enabled before resource B4ADE53C acquire/release !!!

I already entered "bt" after crash.
