Simplest and cleanest way is to install the Cakewalk Command Centre on the Laptop.

Then if you still have all the installers in the CCC download directory copy them across to the CCC download on the laptop and use the CCC to install them.  

If you do not have them then use the CCC to download them again.

EULA allows for installation on more than one machine Provided you are only using one at a time.

What about configuration?  Can I just copy my config file? Where is the config file located?

Which configuration are you referring to?

Most are held in your roaming profile as .ini files

Preference settings. (Edit preferences Audio configuration file and Files initialization file). 

The AUD.INI, which sets your audio interface initialisation file is held in your roaming profile.  It is dependant on the hardware installed.  It is created by CbB or SONAR on starting the program, I suspect that copying it from one machine to another would be full of issues better to let the machine create it for each PC.

Again I suspect that most preferences are unique to each PC environment i.e. Cakewalk Content, Project directory etc and take very little effort to set in preferences.

Your VST directories would need to be added to the Cakewalk Plugin Manager scan paths unless you only install in the default %disk%\Program files\Cakewalk\VST plugins directory.

The only ini file I have successfully transferred from one machine to the next is my Instrument definitions file which even then needs to be tweaked because the MIDI interface and Audio interfaces have been different.

Just letting you know that CCC still is functioning. I just used it last nite and was glad to see it was still working.
