If the license is named as an "Installation License" the main restriction is you need to purchase one license serial number for each computer that the program runs on.
Can I move the software or reinstall the software in future?
Within reason - yes. As long as the software does not continue to run on the old computer you can install the software on a new computer. As a piracy control measure we do limit the number of reinstalls to 2 times in any 12 month period.
Note: we do run an anti-piracy system which can detect multiple installs. But as long as the software (with one serial number) runs on one PC at any one time, you will not have problems.
