Installation

Buildstation 5.4 software must be installed prior to installing 
this Buildstation 5.4 Update 1 software.  Close Buildstation before installing
the update.


1. Copy the file "Buildstation_5.4_Update_1.exe" obtained 
   from the 3D Systems website to the SLA system to be updated. Place the file in a 
   temporary directory.

2. From Windows Explorer, locate the file 
    "Buildstation_5.4_Update_1.exe".

3. Double-click the archive's filename to launch the extraction 
   program. 

     Note: The default destination folder is "C:\Temp\U1". If 
     this is not the folder you want to extract the temporary 
     installation files to, click the "Browse" button and 
     specify a different folder.  The folder you choose must
     already exist as you can't create a new folder in the 
     middle of the installation.

4. Click the "Unzip" button when you are ready to extract the 
   files. 

5. Using Windows Explorer, locate the folder containing the 
   extracted installation files (generally "C:\Temp\U1").

6. Ensure that Buildstation is not running before installing 
   this update.

7. Double-click the install program's filename, "Setup.exe" to 
   launch the installation program.

8. Follow the instructions presented in the dialogs to install 
   the files, ensuring that the correct machine type is selected
   when you are prompted. 

     Note: Using information contained in the Windows 
     registry regarding the original installation location of 
     the Buildstation 5.4 program, the update files will be 
     copied to the appropriate folders.  Only the files that 
     need to be updated are overwritten.  License and 
     configuration files are preserved.

     Update 1 only updates an existing and properly
     installed version of Buildstation 5.4 software so no other
     versions of the software will be impacted.

     After installation, the "Help About" dialog displays "Buildstation
     5.4 Update 1".

9. After successful installation, you may remove the installation files 
   from the temporary directory if desired.  If the WinZip Self-Extractor
   dialog is still open, close it.
