Bought moduel today (2.0).  Loaded on client 4.92 DNN site, Server 2008, 64 bit and when trying to upload bulk user set the module kicks back an error "There was an error while loading import file".  No othere detail.

Client is expecting me to upload these today and I thought this would be the perfect solution.

I believe you need to operate your application pool in 32 bit mode because most 64 bit operating systems don’t support Excel file upload (via the component we use which is Microsoft.JetEngine Database). That component will not operate currently within a 64 bit operating system so you have to force the 32 bit setting.
