PowerBuilder Installer is an online installer with a self-extracting download that leads you through the installation process. The machine will be required to connect to the Internet during the installation process. For those who prefer to use the offline installer, it can be downloaded from the PowerBuilder Installer (by selecting Download Offline Installer in the installer).

When you run PowerBuilder Installer, you will get the option to install SnapDevelop, which includes the two SnapDevelop plugins (.NET DataStore with DataWindow Converter and PowerScript Migrator). Note that you would need a valid license for PowerBuilder Professional or above to use the .NET DataStore with DataWindow Converter plug-in, and a valid license for PowerBuilder CloudPro to use the PowerScript Migrator plug-in. If you do not have a valid license yet, you can install the products first, and then apply for a trial license for temporary use.

Preinstallation Tasks

This topic describes tasks to perform before installation.

  • Log in to Windows as an administrator, as you must have administrator privileges to run the installer.
  • Read the release bulletins for the latest information on the products that you are installing. Release bulletin is available on the Appeon Documentation Center at
  • Make sure the drive on which you install SnapDevelop is not compressed. If compression is enabled on the installation drive, the installer fails.
  • Make sure you have a TEMP environment variable that points to an existing directory location with at least 300MB free space. The installer writes files to this directory during the installation and frees the space after the installation is complete.
  • Close any open applications.
  • Read Software Requirements to determine whether you need to install any software before installing SnapDevelop.

What the Installer Does

The installer installs files and updates the Windows registry.

The installer:

  • Installs SnapDevelop files (as well as SnapObjects runtime packages) in an Appeon directory

  • Installs system files in the Windows operating system path

  • Creates a program group and icons for SnapDevelop

  • Creates uninstall files to identify what needs to be removed if you uninstall SnapDevelop

  • Makes changes to the Windows registry

Registry changes

The installer makes the following changes to the Windows registry:

  • Creates or updates the key in HKEY_CURRENT_USER\Software and HKEY_LOCAL_MACHINE\Software

  • Updates system and user paths in HKEY_CURRENT_USER\Environment

  • Adds the appropriate paths to the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths

Installing in Silent (Unattended) Mode

Install SnapDevelop from a Command Prompt window or script, without displaying messages or windows during the installation process.

Complete installation planning.

  1. Accept the license agreement.

  2. Configure the silentinstall.bat file (located in the SnapDevelop installation folder, for example, "SnapDevelop-2019R2-2323-EN").

  3. Run silentinstall.bat to install SnapDevelop.

Accepting the License Agreement

Accept the Appeon license agreement before running the silent installation.

Edit the silentinstall.bat file located in the SnapDevelop installation package and change the value of set AgreeToAppeonLicense from false to true.

set AgreeToAppeonLicense=false

Silent Install Commands

This topic describes the silentinstall command syntax for SnapDevelop.

To run the silent installation from a Windows Command Prompt, run this command in the installation package:

[ "opt=product" "dir=directoryName" "log=logFileName" ]
[ { help | /? } ]

The parameters can be listed in any order and are not case sensitive. Parameter values are also not case sensitive.

Silent installation parameterDescription
optSpecifies the name of the product to install. For SnapDevelop, the value is "SDEV".
dirIndicates the main installation directory. If you omit this parameter, silentinstall installs the product to the sysDriver\Program Files\Appeon\productName directory, where sysDriver is the main computer drive, and productName is "SnapDevelop 2019 R2".
logNames the log file for the installation. If you omit this parameter, the log file is written to the system Temp directory with the file name, silentinstall.log.
help or /?Command syntax and parameters instead of running the command.

The following example uses all parameters for the silent installation command:

silentinstall.bat "opt=sdev" "dir=D:\appeon\sd190" "log=D:\appeon\install.log"

When installing SnapDevelop, the silent installation writes warnings to its log file if the computer does not have the correct version of any of these items:

  • Microsoft .NET Framework

  • Microsoft .NET Framework SDK

Activating SnapDevelop

For more instructions, refer to Activating SnapDevelop in Appeon License User Guide.

Uninstalling SnapDevelop

This topic describes how to uninstall SnapDevelop.

Use one of these methods to run the uninstall program for the product that you want to uninstall:

  • Add or Remove Programs dialog box

    1. Make a backup copy of any files you might want to reuse (such as DB, source code files) if you plan to reinstall.

    2. Open the Control Panel from the Start menu and double-click the Add/Remove Programs button.

    3. On the Install/Uninstall tab page, select the product to uninstall, click Add/Remove, and click Yes when prompted to confirm that you want to uninstall the tool.

    4. If you are prompted to delete a shared file, choose the appropriate response.

      If the usage count for a system file in the registry indicates that the file is no longer being used, the uninstall program asks if you want to delete the file. Some applications do not increment the usage count; therefore, do not delete a file unless you are sure it is not being used by another application.

  • Silent uninstallation

    Run the silentuninstall.bat file in the SnapDevelop installation package.

The uninstall program removes:

  • Shared and standard program files

  • Folder items

  • Program folders

  • Program directories

  • Program registry entries

The uninstall program deletes file and icon groups, as well as system and user path settings in the registry. Simply deleting directories does not fully uninstall these products.
