DevExpress 2017 — Download and Install (Guide)

DevExpress (Developer Express) provides UI controls and tools for .NET developers. This guide explains how to download and install the 2017 DevExpress components, including prerequisites, installation steps, common configuration choices, troubleshooting, and tips to verify a successful installation. I assume you need the 2017 release specifically (for legacy projects or compatibility). If you need a different year or the latest release, adapt steps accordingly.

Prerequisites

• Windows development machine with administrative rights.
• Visual Studio version supported by DevExpress 2017 (typically Visual Studio 2012, 2013, 2015; check your exact 2017 DevExpress release notes for supported IDE versions).
• .NET Framework versions required by your target controls (often .NET 4.5 or later).
• Sufficient disk space (installations can require multiple GB).
• Internet access for downloading; offline installer option may be available from your DevExpress account if you have a license.

Locate and download the 2017 installer

1. If you have a DevExpress subscription or license:
   • Sign in to your DevExpress account on the DevExpress website.
   • Go to the Downloads or Versions archive and find the 2017 product build you need (e.g., 17.1.x, 17.2.x, 17.3.x). Choose the specific build that matches your project’s intended target.
   • Download the installer (web bootstrapper or full offline installer) for the suite(s) you need (WinForms, WPF, ASP.NET WebForms/MVC, Universal, etc.).
2. If you do not have a license:
   • DevExpress historically provided trial versions; you can request a trial from their site and download the 2017 trial (if still available).
3. Save the installer to a known folder. If you downloaded an offline package (often a large ZIP or EXE), extract it if necessary.

Run the installer

1. Right-click the installer and choose “Run as administrator.”
2. Accept any UAC prompts.
3. The DevExpress Installer UI will launch. Common installer screens include:
   • License agreement — read and accept.
   • Product selection — choose the specific components (WinForms, WPF, ASP.NET, Dashboard, Reporting, CodeRush, etc.). Only select what you need to save space.
   • Target Visual Studio versions — the installer typically detects installed Visual Studio instances; confirm which IDE integrations to enable.
   • .NET Framework targets and optional prerequisites — the installer may prompt to install or detect required .NET versions or other dependencies. Allow or install as needed.
4. Choose installation folder (default is usually fine) and proceed.
5. Wait for files to install. This step can take several minutes to complete.
6. The installer may offer to register DevExpress templates, item templates, toolbox controls, and Visual Studio extensions — accept these to simplify development within Visual Studio.

Post-install configuration in Visual Studio

1. Launch Visual Studio (or restart if it was open during installation).
2. Verify DevExpress templates and toolbox items:
   • New Project -> Installed Templates should show DevExpress project templates.
   • The Toolbox should include DevExpress control palettes for the targeted frameworks.
3. If toolbox items do not appear automatically:
   • Use the DevExpress menu (if present) in Visual Studio to run toolbox configuration/installation utilities, or run the “Toolbox Configuration” from the DevExpress installer again.
4. Confirm assembly references:
   • Create a sample project (e.g., a WinForms or WPF project).
   • Add a DevExpress control from the toolbox to a form/page; Visual Studio should add the necessary NuGet/assembly references or prompt you to do so.

Optional: License activation and project settings

• If you have a paid license, ensure it’s activated per DevExpress licensing instructions (activation might be handled via your DevExpress account or installer prompts).
• For continuous integration or build servers, copy required DevExpress assemblies or configure NuGet/assembly references so builds succeed without interactive installs.
• For web projects, confirm DevExpress static resources (scripts, styles) are correctly referenced and deployed.

Common issues and fixes

• Installer doesn’t detect Visual Studio: close Visual Studio, re-run installer as admin; ensure Visual Studio is fully installed (not just Build Tools). If multiple Visual Studio versions are installed, select the correct one in installer options.
• Toolbox items missing: run the DevExpress Toolbox Creator utility, or use “Choose Items…” in the Visual Studio Toolbox to browse to DevExpress assemblies and load controls manually.
• Design-time errors in Visual Studio: ensure matching DevExpress build version and .NET target; sometimes clearing Visual Studio caches (Component Model Cache) and restarting helps.
• Assembly version mismatches at runtime: ensure all projects reference the same DevExpress version (17.x) and use binding redirects in web.config/app.config when necessary.
• License or trial expiration: obtain a valid license or change project references to a licensed version; trials are time-limited.

Verifying the installation

• Create a small sample app using a DevExpress control for the chosen platform (WinForms, WPF, or ASP.NET). Build and run to confirm runtime behavior.
• Open DevExpress Sample Browser (installed with the suite) to view demos and verify components are operational.

Uninstall or modify

• To remove or change components, run the DevExpress installer again (it usually offers Modify/Repair/Uninstall) or use Windows “Apps & features” to uninstall DevExpress entries.
• For complete cleanup, remove leftover DevExpress folders in Program Files and user-specific extension caches (if you’re sure you won’t need them).

Security and licensing reminders

• Download installers only from DevExpress’s official site or from your organization’s internal distribution to avoid tampered packages.
• Keep licensing records to ensure compliance for production/deployment.

Quick checklist

• Confirm supported Visual Studio version and .NET framework.
• Download the correct 2017 build from your DevExpress account.
• Run installer as administrator; select required components and target IDE integrations.
• Restart Visual Studio and verify toolbox, templates, and sample apps.
• Address any toolbox or assembly issues via DevExpress toolbox utilities or binding redirects.

If you want, I can:

• Provide step-by-step commands for installing an offline package.
• Give troubleshooting steps for a specific Visual Studio version or error message (tell me the exact error).

Frequently Asked Questions

Step 3: Install the Software

1. Close Visual Studio: Before running the installer, ensure all instances of Visual Studio (2015, 2017, etc.) are closed.
2. Run the Installer: Run the .exe file you downloaded. You may need Administrator privileges.
3. Select Products: The installer will launch. Choose the specific components you need (e.g., WinForms, WPF, ASP.NET, CodeRush).
4. Installation Path: Choose the directory where you want the source code and assemblies installed (default is usually C:\Program Files (x86)\DevExpress 17.x\).
5. Proceed: Click Install and wait for the process to finish.

Step 6: Uninstalling or Upgrading from DevExpress 2017

To remove version 2017 before installing a newer one: devexpress 2017 download install

1. Control Panel → Programs → Uninstall DevExpress 17.2.
2. Manually delete C:\Program Files\DevExpress 17.2
3. In Visual Studio: Tools → Extensions and Updates → Uninstall "DevExpress Templates".
4. Clean solution files (bin, obj) of any projects referencing 17.2.

Upgrading: DevExpress recommends using the Project Converter tool (Start Menu → DevExpress 17.2 → Project Converter) to migrate older projects to v18.1+ before updating targets.

Step 2: Running the DevExpress 2017 Installer

Once you have the executable (e.g., DevExpressUniversal-17.2.7.exe), follow these steps for a trouble-free devexpress 2017 download install.
