Can't open Excel attachments

[labuckland]

I get an error message that says the file cannot be accessed because it is a "read-only" or in a read only location. I tried both opening it from the email and saving it to my desktop and opening it. Both ways I get the same message. These are files that I believe were created on Excel for Windows.

I am using a Macbook Pro running OS X 10.6.2

😕

Highlight the file's icon, then
Get Info > Sharing & Permissions

If you're in an Admin account, unlock it (click on the padlock, enter password)
Now you should be able to change it to Read and Write.
