Trying the install once again may prove successful, if something
inadvertently interrupted the operation the first time. Thereafter, the
UNinstall option should be available, if the program offers it.

In addition to attempting a reinstall.... the program manufacturer may have an uninstall or cleanup tool to address failed
installation issues.
In some cases, it may be recommended to follow that route to ensure the subsequent install is successful.
