Basically, No.


The EULA (End User License Agreement) does say that you may install the software on more than one computer at a time, and the number of computers depends on which "Series" you own:

  • If you own a Series B license (your serial number starts with a B) then you may install Vectorworks on multiple computers.
  • If you own a Series E license (your serial number starts with an E) then you may install Vectorworks on two computers, that is (a) a primary desktop computer and (b) either a laptop or a home computer.


With regards to how many of those Vectorworks applications may be in use at a time, the answer is one.


So, if you own a Series B license, you may use Vectorworks on any one of the computers you have installed it on, and the computer on which Vectorworks is being used must have the Vectorworks hardware key connected.


If you own a Series E license, you may use Vectorworks on one (but not more than one) computer at a time.


The current Professional License Agreement is attached below for your reference.


Note that each Vectorworks license ends in 6 characters that remain the same from one version to the next. Hence, trying to run the current version of a licence on one computer and a previous version of that same license at the same time on another computer is contrary to the License Agreement. 


Further clarification on the difference between installing Vectorworks and using / running Vectorworks:


Installing software and using or running software are two very different things.

Software tools are, of course, different in their very nature than traditional, physical tools. For example, if one buys a single hammer, then two different workers could not use that same hammer at the exact same time. If there was enough work to have two workers actively busy with hammers, then two hammers would be purchased.

While software tools may have lagged behind in the past, accidentally allowing concurrent use (due to technological limitations or hiccups), most applications' license agreements for single licenses have only allowed one license in use at a time. (In fact, some software only allows itself to be installed on one computer at a time. Long ago Vectorworks Inc saw that single-installation was an overly restrictive limitation and permitted installation on two computers - but only one concurrent use of that installed license.)

Software tools of all kinds are now catching up and bringing their concurrent-use into alignment with all the physical tools we have all been accustomed to. This is simply a reality of using the contemporary tools - in this case, software. Software may be a greater capital investment than a hammer, yes, but software is a necessary contemporary business expense.
