## 2.1. Maintenance of program installation

to perform the program maintenance, insert the installation disk into CD-ROM drive and select position “Install/uninstall program...”. The proper installation program will start, with following proposals:

- program installation modification,

- next program installation

- program uninstalling.

First two options are called “Maintenance of program installation”. First one is used for adding or removing of components, which are not necessary for program operation (e.g. help files or manual in electronic form). Second option means repeated copying of already installed components from CD on a hard disk drive and is used for refreshing of already performed installation, if there is a suspicion that a file on a hard disk drive can be damaged (e.g. after virus infection) or after failed updating of package manager.

! If after program installation an update by means of “Package Manager” has been done, then updated files are newer, than these on installation CD. In such situation, if repeated installation is necessary, the updating must be repeated as well!
