How Does the Licensing Work?
The commercial installation package is the same you might have used for trial purposes, and is publicly available on our Web. When you make a purchase, we will send you a license file by e-mail. You then run the License Manager utility on your computer, install the license by pointing to the license file received, and you are done.
We normally send the license file during a few hours after your order. In general, however, it can take up to one business day.
Happy New Year!

i think most of my applications are compiled with x86 option. Made some tests today: worked well.
Next week i will test by our customer. Maybe we purchase ist shortly, can we install the download version and use a key to unlock after the tests ?

thank you for pointing out this problem. I have attempted to reproduce it using QuickOPC.NET 5.03.446.1 (same as you), on Windows 7 Enterprise (x64, English). And, when I tried to run the Demo Application (.NET 2.0), I got following (after expansion):

This appears to be the same problem as you are seeing. My initial investigation suggests that that the demo application is compiled with "Any CPU" as target, causing 64-bit Windows to start it in 64-bit mode. However the QuickOPC.NET assemblies it is trying to load are targeting "x86" only, and are thus rejected.
What we need is to make the system to start the application in 32-bit (x86) mode instead. This can probably be done using the CORFLAGS utility from the .NET SDK, however that is more a workaround rather than good solution. Better solution would be to have the executable (demo application) compiled for "x86" (not "Any CPU") as well. I will check if this works well, and if so, we will post an updated build. I think this also explains why your own application may work - if you have the target set in that way.
I will post follow-up information here when it becomes available.
Note: Native 64-bit product is in development.

tried it from the scratch in a bigger application which runs on 64bit Windows. IT WORKS. So why does the sample not run.

i have installed the QuickOPC.NET Version on a 32bit System an everything seems to be ok. But the target system is a Server 2008 64bit and also Windows7 64bit. I tried it on both systems and it does not run, even the demo does not start.
The OPCLabs.KitServer runs and i can see all tags are alive. So what can i do to make the QuickOPC.NET run on that systems.
It is essential for the most projects, because i can not decide which (windows) operation system is underlying my applikation.
I tried it in VS2010 VB Compiler and get a (German) Error, see Attchment.
Happy New Year to all people reading this.
