Hi,

856KB, I think, it is not large files. It maybe file mime types issue. PLease make sure

• MIME Type definitely exists for the .EXE extension.
• configure Execute Permission to "None"

For more information, you can refer to the blog:

Hi,

2kb? But I think you can try setting the "Maximum allows content length" value in IIS Manager -> Features -> Request Filtering -> Edit Feature settings.

Hi,

I think you can try removing your handler mapping for .exe file. Just add mime types for it. 

• Now once you’ve single clicked on your websites root folder in the nodes, select “MIME Types” from the icons in the middle stage.
• Now click the “Add…” button on your right hand side and add the text exactly as below.
• You’re done! Go head to that http:// address that you have and now the file will download from the IIS 7 web server correctly!
