How to avoid Warning message after downloading to Excel

Hello everyone,

  I have always faced the issue of warning message "The file you are trying to open, 'filename.xls' is in a different format than specified by 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?" while downloading data to excel sheet from internal table.

Finally I came across a solution which helped me get rid of this warning.Even though it is not a permanent fix, this can be used in some cases.

Do the following steps:

1. Open your Registry (Start -> Run -> regedit.exe)
2. Navigate to HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\12.0\EXCEL\SECURITY
3. Right click in the right window and choose New -> DWORD
4. Type “ExtensionHardening” as the name (without the quotes)
5. Verify that the data has the value “0″

This helped me resolve the issue.Hope it will be useful for some of you guys.

Regards
