Custom automated installation
Installation of Web Screen Saver produces different operations. Many of these operations need parameters that the user inputs when the standard installation is ran. You can also produce a custom installation with global parameters. Doing this, you can automate the installation for a quick deployment on several computers.
Steps for installation:
- Create directory,
- Copy files,
- Update Windows registry,
- Update system.ini,
- Create shortcuts.
Create directory
First, the program directory is created:
C:\Program Files\Vaugouin\Web Screen Saver
The program file webss4.scr is copied in the Windows directory. However, the program directory is created to hold the uninstall file created by the installation procedure.
Copy files
Several files are created or updated on the hard drive:
| File | Destination |
| webss4.scr | Windows directory |
| msvbvm50.dll | System or System32 directory |
| comdlg32.ocx | System or System32 directory |
| webss.wss | Configuration file, if stored locally |
Update Windows registry
Windows registry is updated. Download the attached webss.reg registry file and save it to disk.
Open the webss.reg file using a text editor and update it depending on your configuration.
First, change Windows path.
Find "C:\\WINDOWS\\" string and replace it with correct value, for instance: "C:\\WINNT\\" on a Windows NT 4 or Windows 2000 computer.
Remark: Double every backslash in the program file path.
