Yes, it is what I need.

I have downloded the file and acted upon the instructions provided.

When I navigate to the folder in which I stored the RowLiner.xla file, and
click OK my Excel was closed showing message:

"Microsoft Office Excle has encountered a problem and needs to close. We are
sorry for the inconvenience."

I am using Excel 2003 (11.5612.5606)

Now, "RowLiner" is listed in Add-ins list but unchecked. When I check it and
click OK it show same problem.

Is there some error from my side or this version has not suport for version
2003?
