When I open Excel file, it goes to Protected view
Can any one help me???

Could be. First, how do you know it's in "Protected view"? What I'm looking for is an answer something like this:

• "As Excel opens the worksheet, a window pops up saying '1364: Protected View is enabled.' "
• "After the worksheet is open, there's a box on the status line at the bottom saying 'Mode: Protected'."
• "I can type data into column A alright, but whenever I try to enter data in other columns I get an error message saying 'Protected mode — data entry is barred. Turn off Protected mode to continue.' "

I'm just making these messages up; what I really need is for you to explain (exactly) what you're encountering.

Could not display data,
just a new window is appeared in bottom, marked file name (protected view).

It is opened 2nd or third time after closing those protected view windows.

Thanks your response
