Reserve Memory error: Can't reserve 512 Mbytes of memory for the memBase

Hi folks,

I'm trying to use 0.57 on a Win7 home premium x64 system with 8GB ram, Intel i7-2600, Nvidia GT 545. The program does not start and shows the above error message. I tried to run it as administrator and using all the compatibiliy options without success.

Is that because 0.57 is only available for x86 systems? Any suggestions how to make it work on a x64 system? Or where does this error come from?

Strange enough I tried the 0.55 x64 version as well and it terminates with a page fault.

Any help would be greatly appreciated! Thanks in advance,
Sven

The x86 version of Demul should work just fine on 64-bit Windows 7.

0.57 works here on win7 x64

Well, thanks for the info but that doesn't help me much....
I've tried many things, like starting from scratch on different machines. The error stays the same. What does this error mean, where does it come from? Do I need any special DLLs or anything?
Thanks again,
Sven

I got similar error (but with 384MB instead of 512) because of, belive it or not, Commodo Antivirus. As soon as I installed Kaspersky Internet Security, demul started to work.

Ok, thanks for the hint. For me it was Checkpoint Zone Alarm (free version). After de-installing this firewall software and using the Win7 internal firewall, Demul started again. Pheww!
Thanks again friends
