VB document cannot be executed

Hello
I just made my first VB document, migrated it and tried to run it on my browser but it comes up with the options

Open, Save, Cancel, Help

when i hit open, it says "count not start application"

is that because of some security feature in my browser

also i was wondering what the type : octet stream meant?

if you used VB instead of VBA, then you need to compile your program before it will work, and it will not work as a document. It wil work from the run command, and wil start and end in its own process. VBA will work in a M$ application.
