Yes, that will work. You can save some time if you have a second drive available (internal or external) and kept the downloads in the Command Center.
By default the Command Center stores the installers in "C:\ProgramData\Cakewalk\Command Center\Downloads." The actual location on your PC may be found by going into the Command Center settings by clicking the gear in the upper right of the Command Center UI and then click the path tab. The location is set in "Download Path."
Copy the installers into a folder on the second drive. Then after installing the Command Center on the new system drive, go into the Command Center settings and point the download path to the folder you copied. Then install from the Command Center. the Command Center will use the existing installers rather than download everything again. From there, you can either continue using the new location or point the download path anywhere you wish.
