2. Why this happening in Excel everytime?

[san]

Hi friends,

For the past few months, everyday I have to download 3-4 files from my
banking site and I save those files in *.xls file format.

But when I open any of these *.xls files, I get this dialog box.

MICROSOFT OFFICE EXCEL

""The file you are trying to open, 'abc.xls', is in a different format than
specified by the the file extension. Verify that the

file is not corrupted and is from a trusted source before opening the file.
Do you want to open the file now?""

YES NO HELP

After I click YES button, file opens in Excel. But my problem is for every
file I want to open I have to do the same steps. Now,

all I want is that all these *.xls files open without this dialog box coming
up. Is there any way by which I can get rid of this

dialog box once for all.

Thanks in advance.

Hi,

I used trial software "XLS to XLSX Converter" which you suggested me. When
I tried to convert, it says this for every file ""Cnv2x failed! Did you
installed .Net v2.0?"" My PC already got installed .Net Framework v1.1,
v2.0 SP2, v3.0 SP2 & v3.5 SP1 and when I try to uninstall v2.0 SP2 it gave
me error that it cannot be uninstalled because it will affect other
applications that are installed. Now, what should do I do? Please help me
again on this.

Thanks in advance.
