Licensing
Protection Types
InduSoft Web Studio and CEView support the following protection types:
Hardkey
An encapsulated chip that must be physically connected to the computer's parallel port (LPT1)
or USB interface.
The software license resides in the hardkey, and you cannot share this license simultaneously
with more than one other copy of software in the network. If you connect the hardkey to another
computer, then you effectively transfer the license to that computer.
Using the parallel port hardkey does not prevent you from connecting another device — such
as a printer — to the port. The hardkey should be electronically transparent to other devices
connected to the parallel port. You simply connect the hardkey to the computer and then
connect the printer cable to the hardkey. However, you may encounter problems if you install
more than one hardkey (for different products) on the same parallel port.
On the other hand, while using the USB hardkey, the USB port cannot be shared with any other
device.
Caution: Be careful when installing or removing a hardkey from the computer's
parallel port. We strongly recommend that you turn off the computer and
disconnect it from the power supply before installing or removing a hardkey.
Softkey
When you install InduSoft Web Studio or CEView, the program generates a unique code called a
Site Code. You can send this site code to your software vendor, who will then generate a license
code called a Site Key to match your site code. The site key installs the InduSoft Web Studio or
CEView license on your computer or Windows Embedded device.
Note: When you use a softkey, IWS records the license in the computer's (or
Windows Embedded device's) non-volatile memory. If this device is damaged, you
will lose the license.
