I checked for the block, but all the files are clear; the code works well on 2/3 servers. It is only SmarterASP.NET web hosting that is causing failures. I'm going to ask their support staff if they might be willing to run the Webkit TroubleShootingTool.exe .
The SmarterASP.NET tech support understandably will not run the Webkit TroubleShooter.exe on a shared server. They simply recommended I try dropping mscrv100.dll into the /bin folder. That does not work. Would this Exception be expected if the correct C++ runtimes were not installed on the server?? I'm tempted to move this site to a different hosting service, where I have already tested the app and know that the Syncfusion functions work well.
Prakash, Thank you for your help with this and your offer to go 'one-on-one' to try to solve the problem on the server. I worked around the problem by moving the web application to another hosting service, where it worked perfectly without further adjustments. There was most likely a versioning problem with the VS C++ runtime, but the tech support did not seem to be very knowledgeable.
