Trying to send an exe file in Gmail throws up an error saying that your email cannot be sent with the attachment as it is a security risk to Gmail. The easy way out is to hide the extension.

Solution : 1

Rename the ABC.exe to ABC.txt . Attach the ABC.txt file in your Gmail and do the reverse at the receiving end.

Solution : 2

Use Winrar/Winzip/etc and make ABC.exe to ABC.rar/ABC.zip/etc.zip before sending.

Once you receive the file from the mail just reverse the step. Either change the extension of unzip the file.
