Issues running large executables (v3.0.13 X32 XP)

I have a P4 HT, My system internet browser is Firefox, OS: XP sp2 32bit, AV: None Security Apps: Comodo Firewall Pro 3.013, Comodo Memory Guardian 1.0.16b

3DMark06_v110_installer.exe is an over 500MB setup file.
It takes a long time to get any V3 interactive alert.

The origina installed had a small corruption. Launching with D+ disabled is fine and run instantly. With D+ enabled It cannot be launched and an invalid w32 dialog popup is displayed before you get an execution alerts after 30 secods or more.

A correct 3DMark06_v110_installer.exe doesn’t trigger any invalid 32 bit app popup but the run executable alert takes a long time to display.
