software installation dialog box.

"Add/Remove" the software.

2.4 User Rights
2.4.1 User Rights in MS Windows XP/Server 2003
Note the following points relating to user rights:
To be able to work with STEP 7, you must log in at least as a user (no guest login).
To install the STEP 7 software and HSPs, set up modules and change settings with the "Set
PG/PC Interface" application, you require administrator privileges.
To use optional packages, check which rights are required for the specific optional package.
If projects are stored on NTFS drives, users must also be allowed full access here. This also
applies to the folder with the HSP updates (default: C:\HWUPDATES). Access within the default
project directory S7PROJ is enabled automatically for all users.
Note
• Working with user rights is enabled only for STEP 7 itself. There is no guarantee that user rights
are adequate for optional packages. Here, administrator or power user rights may be necessary.
• After installing / uninstalling new hardware, the computer must be started up at least once with
administrator privileges.
