Installation on Windows 7

WebMAP for Silverlight is not officially supported on Windows 7. Windows 7 has been EOL since January 2020. WebMAP for Silverlight installation fails on some Windows 7 environments, because its requirements fail to be correctly installed.

However, it is possible to execute WebMAP for Silverlight on Windows 7 if you really need to. You just need to carefully install WebMAP for Silverlight requirements before executing the WebMAP for Silverlight installer.

Windows Update Agent

Some Windows 7 installations have a broken certificate chain, which impedes the installation of WebMAP for Silverlight requirements. We need to install Windows Update Agent for Windows 7 in order to restore the certificate chain.

Download Windows Update Agent from one of the following links:

• For Windows 7 64 bits (x64): link

• For Windows 7 32 bits (x86): link

After downloading install it. Then reboot the machine.

.NET 4.6.2

Download the .NET Framework 4.6.2 Offline Installer (not the web installer) from this link and execute it. If you get this screen:

Great! The certificate chain on your Windows 7 is OK. You can reboot your computer and skip ahead to VS Build Tools 2017 installation. But, if you got this screen:

Then the certificate chain on your Windows 7 computer is broken. You need to restore the certificate chain by installing Windows Update Agent as described in the previous section. There are ways to bypass the certificate chain and force .NET Framework installation, but VS Build Tools 2017 installation also needs a working certificate chain, so it is better to fix the certificate chain anyway.

VS Build Tools 2017

Now that .NET 4.6.2 is already installed, VS Build Tools 2017 installation should be smoother. Installing VS Build Tools 2017 is relatively easy, we just need to be careful to select the correct workloads when installing.

Download the VS Build Tools 2017 installer from here. You will need a Visual Studio Subscription to download the installer. Download the x86 version, even if you have a x64 version of Windows:

Then execute the installer. If you get this screen:

Then your Windows 7 has a broken certificate chain. You need to restore the certificate chain by installing Windows Update Agent as described in previous sections. After installing Windows Update Agent, reboot the machine and relaunch VS Build Tools 2017 installer.

When the installer is successfully launched you need to select "Web development build tools" workload:

If you want to reduce the installation size, you can unselect most of the optional components on the right side, but be sure to keep ".NET Framework 4 - 4.6 development tools" and "NuGet targets and build tasks":

Hit "Install" button. After installation, you can close Visual Studio Installer and reboot your machine.

WebMAP for Silverlight

Now that WebMAP for Silverlight requirements are installed, you can execute the WebMAP for Silverlight installer. If you don't have the WebMAP for Silverlight installer, please talk with your account manager or contact [email protected]. You can also apply for WebMAP pre-release from this link.

Given that requirements should be already installed, the installer won't attempt to install anything by its own and will just install WebMAP for Silverlight. You should reach this screen without interruptions:

When you launch WebMAP for Silverlight it will execute properly:

Now you can proceed and analyze your source code. If you get any errors please check our general troubleshoot.
