Dreamcast emulator "Demul" refuses to run without uninstalling CIS

1: CIS version:
2: OS version:
Windows 7 Ultimate x64 SP1
3: What you did:
Download and run demul.exe in the website below, latest and older versions.
4: What you actually saw:
Error message “Can’t reserve 512 Mbytes of memory for the memBase”.
Disabling individual components in CIS can’t solve the problem, CIS must be completely uninstalled in order to make demul.exe run.
5: What you expected to happen or see:
The program runs fine with Avira and Kaspersky installed.
6: If possible attach a screenshot illustrating the GUI problem

I have no issue opening application on CIS can you check with this version? Also do you have enhanced protection mode enabled or disabled under HIPS settings? If issue still occurs with the newer CIS version please provide a diagnostic report thanks.

Installed and solved. Thanks!
