"excel found unreadable content in test.xlsx. want recover contents of workbook?" if click yes, able see contents in document.

similarly getting warning message .docx file well.

this c# code using:

response.clear(); response.contenttype = "application/octet-stream"; response.addheader("content-disposition", "attachment; filename=" + filename); response.outputstream.write(content, 0, content.length); response.flush();  httpcontext.current.applicationinstance.completerequest();

update: when download file in windows forms app working fine , problem web app only.

(both training , prediction can done in parallel, since problems assumed ...
