I'm guessing you have a processor that supports DEP. My guess would be an AMD processor as there more common to have conflicts. I'm guessing DEP is getting confused do to your Virtual Machine software and is shutting down legitimate processes.
DEP = http://en.wikipedia.org/wiki/Data_Execution_Prevention Basically, when a virus tries to inject a dll or something into a program or modify the memory of a program, DEP can pick up on it and deny it. Running 64bit Windows Xp/Vista there have been known to be conflicts with some 32bit software(SC and Mods sometimes have a conflict). There have also been problems with older software. Basically DEP is a form of hardware virus-protecter. To turn off: http://www.mydigitallife.info/2007/01/15/disable-and-turn-off-or-enable-or-turn-on-data-execution-prevention-dep-in-windows-vista/ Also, why use the 64bit version? No programs really take advantage of 64bit, and then theres driver issues.... ![]() ![]() ![]() ![]() ![]() ![]() |

If you have more than 2 GB of RAM (yes 2, not 4, but the exact number may depend on some complicated issues I don't want to explain), then a 64-bit version of Windows may be needed to have access to all of it. As for DEP, it is for helping close some types of security holes in programs that could potentially allow code to execute (without DEP); however, it will not prevent you from installing a virus yourself by installing something that contains it. It does this by preventing code from executing in any area not marked as containing program code.People shouldn't be so quick to blame Microsoft for the problems with third-party applications. Everything Microsoft is advocating software vendors to do with their programs in Windows Vista could have (and SHOULD have) been done ever since Windows 95, basically 12 years ago. Here I will list each thing that programs need to do in Vista, that could have already been done in Windows 95 but was optional, along with the name of the Vista feature related to it that makes it now required.
Those are the main features in Vista affecting program compatibility, as far as I know. Basically it is the makers of the incompatible third-party programs who are to blame for their lack of compatibility with those two Vista features. Not abiding by those practices has also caused compatibility issues to some extent for people running them on Windows 2000 or XP - particularly for system administrators trying to get programs to run for the non-administrative users. This has been quite a problem with various third-party programs for years and many people have been very frustrated by it. For quite a long time, system administrators have had to make a compromise to run such programs if the program is a necessary program - giving users of the system administrative access on their user accounts, which compromises security. UAC is partly Microsoft's attempt to force developers to make their programs store their data and settings where they should have been storing them all along.

Hmmmm.....
I think there could be a possible problem when downgrading from Vista to XP. Vista and XP both have cryptography control on them, preventing installation of USB devices that are not 'digitally signed' or manufactured by Microsoft. When downgrading (my friend did this), the cryptography database corrupts, preventing installation of any unsigned USB devices in XP. (Microsoft actually acknowledged this , but I can't find thier link yet!).This also occurs in VMWare Machines AND when downgrading, on certain models, from Vista to XP As for DEP, it is for helping close some types of security holes in programs that could potentially allow code to execute (without DEP); however, it will not prevent you from installing a virus yourself by installing something that contains it. It does this by preventing code from executing in any area not marked as containing program code. I only give my VMWare Machines 2GB each, that means that I can install 25 VMWare Machines on one hard drive. My Vista PC curently has 30GB, 6.50GB used. |
