Virtual XP under Windows 7 ?
#1
I run Windows 7, 64 bit. MS gutted the 16 bit part of the OS for 64 bit versions while retaining the 32 bit backward compatibility.

I have some old programs written in FORTRAN and compiled with a 16 bit compiler. All worked fine on my former XP 32 bit machine.

Can I setup a 32 bit virtual XP OS on my windows 7, 64 bit machine.
I have a virgin copy of 32 bit XP Pro.

(Not a dual boot -- just a virtual machine inside the Win7 OS shell.)

I never got around to trying it but here is a link to a description of the feature:

http://windows.microsoft.com/en-us/windo...-windows-7

This Google search should get you a lot of references: [ "windows 7" running | mode "Windows XP" ]

(The quotes are part of the actual search, the brackets are just to set it apart and should not be included.)

Sweet Dreams,

Hi Mongo,
If your Windows 7 is the "Professional" version, there is a free tool for it called "XP Mode". This tool sets up a Virtual Machine, and installs a copy of 32-bit Windows XP in it. XP Mode does not come preinstalled or even on the installation media, you must download it yourself, but there is no additional licensing charge for it, or for the virtualized copy of XP. You can then install applications to the XP as you wish. If you have an application installed in XP Mode that you use frequently, you can place an icon for it on the Win7 Desktop that will automatically start the VM, and then launch the application when you activate the icon.

As an alternative, you can install VMware Workstation from the VMware folks, and load any OS into it you wish, including DOS. VMware Workstation is not free, but I think you can find it fairly inexpensively, especially if you watch for specials. At my company, we have long experience with VMware products, and find them exceptionally stable, predictable, and perform well.

As another option, VMware distributes VMware Player for free. It can run VMware VMs, but not create them. If you can come up with a way to create a VM, then you can use VMware Player to run it similarly to VMware Workstation. If you are interested in this avenue, PM me and I'll be happy to discuss it.

Hope this helps.

you can also run virtualbox which is a free (for personal use) d/l, has more options (like multi-cpu threads, etc.) than Win7 XP mode and does not require 'professional' to run.
Now owned by Oracle, but it's open source at it's heart..

Thanks -- yes, it's Win 7, 64 bit Pro.
HerbM -- good to hear from you. Glad you are doing OK post surgery.

While we're on the topic, another solution would be a good open source FORTRAN compiler.
I've seen some; but, have not tried them. Since I am a dinosaur from the age of the Cold War, I'm still more proficient in FORTRAN than any other language. I'm not paying an arm and a leg for the Leahy compiler; nor the Intel compiler, since my coding these days is not for income generation.

Suggestions for an Open Source, 32 or 64 bit FORTRAN compiler/linker for windows?
GUI interface would be nice; but not essential.
