I'm currently running Windows XP, but am evaluating Windows Vista on a virtual machine (on the same PC). I'm a registered DOpus user for a few years now, and plan to upgrade to 9 as soon as it's available. I'd like to run DOpus 9 in XP but also run it in my virtual machine to try out its Vista features. I know I could just put a 30-day evaluation copy of DOpus on the virtual machine, but I don't know if I'll be ready to give up XP by then, so I may keep the virtual machine around longer than that. Is it considered acceptable to use the same license on a machine and simultaneously on a virtual machine running on the same physical machine? I know software companies have some varying rules on virtual machines, so I thought I'd just ask.
I have often wondered the same thing myself as I used to do a similar thing with Dopus 8 when moving from 2000 Pro to XP but it wasn't a virtual machine I was running just a dual boot, so there was only ever one physical installation of the software.
I myself am looking forward to getting the USB flash drive licence as ther is nothing worse then going to someones elses PC and not finding DOpus. You could consider that as an option if the licence doesnt cover your Virtual Vista Machine...

This is in the licence section of the new reference manual
On a machine for which you have a license, you may install the software on multiple operating systems or virtual machines for use by one user at the same time.[/b]

You might be better asking GPSoft directly about this kind of thing.
They're probably too busy finalising the Opus 9 release to keep a good eye on the forums so things that only they can answer might slip through unless sent to them directly.

Excellent, thanks. Now I feel stupid for sending them an e-mail, but it's good to know 
Just in case anyone is curious, I did ask in my e-mail if the 64-bit version would be a separate product, and the answer was that no, it will not be. So if you get a license now, you will be able to use the 64-bit version when it comes out without having to buy another license.
I have to say I really like DOpus's licensing provisions. For my upgrade cost I can run DOpus on my own system, a laptop (if I can ever afford one) plus any multiple operating systems or virtual machines on either of those systems, PLUS a "roaming" copy on a thumbdrive for an extra $10.
I have great respect for a company that is willing to treat me like a person and not introduce stupid licensing restrictions or try to tie a license to a particular device or system rather than to a person (like new motherboard = new computer = need a new license -- what Microsoft has been doing). This probably isn't something that software developers are used to be complimented on, but kudos to GPSoft for having a sensible licensing scheme and a fair, sensible EULA. For a change I actually feel like I'm getting more than my money's worth out of a software license.
Would you believe that many people complain about the: "high cost of an Opus license"?
I don't really know what the value of an Australian dollar is, but $85 comes out to somewhere around $69 US. That's a bit steep, but not terribly out of line with the other software I use.
You really only have a high up front cost anyway. GPSoft seems to be pretty good about offering discounts to upgrading customers. The 8 -> 9 upgrade was only $48 US for me, with one USB license. That's much more in line with what I expect to pay for software.
I can understand the complaints, but I don't think their prices are unreasonable.
