I have ECC 6.0 Ehp 7, abap2xlsx 7.0.1, Windows 7 sp1 64-bit and Excel 2013 32-bit.
When I execute demo report ZDEMO_EXCEL22, selecting "Direct Display", Excel pops this error message before displaying:
"The file format and extension of '~SAP{22D174FB-27D0-449B-A398-B7FF87FAF40A}' don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?"
This could be difficult to explain to end-users. Has anyone found a way around it?
