PROBLEM TO BE SOLVED: To provide an upgrading method that can safely upgrade components of software such as a customized program module. SOLUTION: A software execution environment 9 of a computer 1 has a flag 14 for indicating whether a component of software such as a program module is customized or not. Meantime, an upgrade kit 31 has software components upgrading the version to be introduced to the execution environment, a version upgrade program 33, and flags 37 for indicating whether or not each software component is compatible with a customized software component in the software execution environment 9. The upgrade program 33 compares the flags 14 of the execution environment 9 and the flags 37 of the upgrade kit 31, and in consideration of the comparison results, determines whether or not to execute an upgrade.
