A question to start with: are you working with LabWindows/CVI (i.e. text C code) or LabVIEW (i.e. graphical code)? There is no "Professional" version of LabWindows - only Base of Full Development System (FDS) - if you are using LabWindows/CVI the see the comments at the bottom.
If you are using LabVIEW and do not have the Professional version, it is possible to purchase the Application Builder separately. This add-on will allow you to generate executable versions of your programs and will also allow you to create distribution kits to help simplify the installation process on the other computer.
It is not possible to simply copy the your application from one PC to another - there are also potentially licencing implications if you install multiple copies of
LabVIEW on multiple computers. The easiest and safest way is to buy the Application Builder - it can be used with both LabVIEW Base and LabVIEW Full Development System (FDS).
LabWindows/CVI
______________
As far as I understand, both LabWindows/CVI Base and Full Development System packages allow you to create DLLs or EXEs which you can then distribute/install onto other computers. You could therefore create an EXE version of your code and move this across onto the other computer.
The easiest way to do this is to get CVI to create a distribution kit automatically for you. This will ensure that all the necessary files (in particular the CVI run time engine) is installed correctly on your other computer.
Further detailed information can be found in the LabWindows/CVI User Manual - see Chapter 3 (Build Menu) at the following link:
