Hi Mark,
We regret for the inconvenience caused.
Syncfusion extension installation will take around 10 to 15 minutes and also Visual Studio instances should not be opened during the installation. However, this time may vary based on the machine configurations (Visual Studio installed, RAM, Hard Disk space etc.)
Thanks for sharing the log files, but we are unable to find the Syncfusion installer log files in the shared zip, since %temp% folder might have been cleared.
Please run the below utilities to complete the installation successfully.
1. Install the Syncfusion extensions by following the steps suggested in the below documentation link.
https://help.syncfusion.com/common/essential-studio/utilities#vsix-installer 2. Run the WebConfigSwitcher.exe from below mentioned location.
Location: { Program files folder}\Syncfusion\Essential Studio\{Essential Studio version}\Utilities\WebConfigSwitcher }
Now you can continue your development work.
Still if you face any issues, please follow the steps suggested in the following knowledge base article link to generate the complete installation log generated by our tool and share to us before clearing the temp folder. It would be much helpful for us to analyze the reported issue.
