I have a working Microsoft Access 2007 database on a Windows XP SP3 PC with two .mdb files (front end and back end).
I zipped and emailed the resulting compressed file to my son as an attachment.
He received the email on his Windows 7 64-bit PC and successfully saved the attached compressed file.
When the compressed file was opened and the two .mdb files were selected and copied, the subsequent paste was blocked by the Windows Security as a potentially harmful file.
There appears to be no option to override. I know that the file is safe, but I am stuck.
Thank you in advance for your assistance.
