I'm just following up on my January 20, 2012 response to see if my sample has been tested. Since I sent it, I have dowloaded updates for the WebGrid 7 and it still will not export when deployed in a 64-bit only app pool. It will export on my local machine when running in a 64-bit only app pool, but I don't consider that valid since that is where I have the developer tools.

Is there some IIS 7 setting or other configuration setting that could cause the grid to allow exporting in an app pool that is set to allow 32-bit applications, but not one that is set for only 64-bit?

Hi Handy,

Thanks for the quick reply. I'm doing some more research on this, and was able to get it to work on my Windows 7 64-bit system with my app running in 64-bit mode, but my system is not a deployed system. I am a developer and have the WebGrid developer tools installed locally with the WebGrid dlls in the GAC. Our deployed systems, of course, do not have the developer tools and do not have the dlls in the GAC. They are just in the bin directory of our application.

Is there a requirement that the dlls be in the GAC for a deployed 64-bit system? Was the sample you showed in the video on your development machine, or a deployed system? So far, that is the difference I see on my end. I'm hoping to get my hands on a deployed test system and try a few things like putting the dlls in the GAC to see if that fixes it.

Thanks,

Tony
