How to open 11B extension file on Windows 7?

[Neyolight]

Good Evening Everyone :-D

Someone sent me a setup file of a program on my email. When I downloaded it I realised its got a file type "11B".

Firstly, I dont know what type of file extension is 11b and secondly Im unsure how to open it. Its a set up file though. Ideally it would have a .exe extension. :roll:

I have windows 7 on my laptop.

Any ideas?

There is an 11B extension used in ProFile 2011 software.

Perhaps the SMTP server/client changed the extension as a save guard.

Have you tried copying the file and changing the extension to exe or msi and attempt to execute it.

You may want to perform this exercise in a "Sandbox", unless you know the sender well.

I changed the extension to .exe and it worked !

The file was sent by a known person so no threat of virus or spam.
