Hi Luca,
Thanks for the update.
As per your shared log files, we suspect that some other msi\setup installation is in progress in your machine and blocking VSIXInstaller.exe to install VSIX from Visual Studio 2019. Could you please kill or end the msi/setup installation process from Task Manager?
Example:
After that, you can follow the steps below to install Syncfusion Windows Forms Extension.
- Close Visual Studio 2019 and run the command prompt in Admin mode
- Navigate to the “SyncfusionVSIXInstallerConsole.exe” location
Location: {InstallPath\Syncfusion\Essential Studio\Windows\19.1.0.54\Utilities\Extensions\VSIX Installer
Example: C:\Program Files (x86)\Syncfusion\Essential Studio\Windows\19.1.0.54\ Utilities\Extensions\VSIX Installer
- Execute the following command for SyncfusionVISIXInstallerConsole.exe
Argument: SyncfusionVSIXInstallerConsole.exe /action:install /isinstaller:true /platform:"Windows"
Example:
- Now, open Visual Studio 2019 and check Syncfusion Windows Forms Extension will be installed.
If still you are facing the issue, please follow the below steps to install the Syncfusion WinForms extension manually in your Visual Studio 2019.
- Close the Visual Studio 2019.
- Double click on the Syncfusion Windows Forms VSExtensions.vsix file which is available in the below location.
"C:\Program Files (x86)\Syncfusion\Essential Studio\Windows\19.1.0.54\Utilities\Extensions\Syncfusion Windows Forms VSExtensions.vsix"
- Then click on the Modify button to install the extension in your Visual Studio.
- After completed the installation open the Visual Studio and check the Syncfusion WinForms extension for your development.
