If you want to run MLwiN you will have to run it under Windows, either through virtualisation software which is available commercially (for example
www.vmware.com/products/fusion/ or
www.parallels.com) or for free as open source software (for example Sun's VirtualBox), or by dual booting using Apple's Boot Camp. All of these require a legal copy of Windows to use on your Mac.

Is MLwiN compatible with Microsoft Vista or 64-bit systems?

Yes, MLwiN 2.1 is compatible with Vista. It hasn't been tested on 64-bit systems, but please let us know if you have any problems with this. For further info about compatability -

We are currently re-designing our network, which means that our MLwiN users will have to access the data MLwiN uses through a Citrix-"window" and they will not be allowed to put the data onto their local hard disk. This means that MLwiN cannot run on their computers but must reside in the secure network, and either be processed on the Citrix-server/Citrix-desktop, or running on a dedicated application-server.

We do not have a Citrix system here aty CMM to test MLwiN on, so cannot give a definitive answer, however we have had reports of people using MLwiN successfully on this and similar systems. MLwiN 2.1 should have more success that previous versions as it no longer attempts to write files temporarily to its program directory.
One thing to note is that MLwiN loads the whole data set being analysed into memory, so if your users are running models on large data sets on the same machine you may run into memory issues. Running more complex models can also be quite CPU intensive. Whether this is an issue for you will depend on the number of processors in your server machine and the number of simultaneous MLwiN users. Each instance of MLwiN can only make use of a single processor, so as long as the number of copies running a model is less than or equal to the number of processors in the machine there should be no slowdown compared with running it on the user's machine.
