I am using v3.8.0.0. All I am trying to do is open an existing .xls and then saving it with a new name. When I try to open the new saved file MS Excel tells me that the file is corrupted.
Here is the code that I am using in C# (xls is attached):
Here is the original file, 2005compliancetool.xls. The other file, TestProject2_42006.xls, which is attached above, is what gets saved and getting the error.
It is not my spreadsheet. It is provided by the State of Ohio and it must be returned to the state as is. The state releases a new version every year or two. The state just released a new version and it is working. I have attached it if you would like to compare. As far as the password goes, your guess is as good as mine. Thanks for the help!
