Hello,
Maybe someone has an idea on the following problem:

computer 1 - Win 7 Office 2007
computer 2 - Win10 Office 2016

Excel 2007 file with macro (macro minimal only set a sheet hidden true or false depending on a celle). The file contains several sheets, some with drop-down lists.
The file works fine under computer 1

Test 1:
Open the file under Computer 2
1. Error message: "Excel has found unreadable content in .... Do you want to repare the contents of this workbook? If you trust the source of this workbook, click 'Yes'.
2. After I clicked on Yes a window is displayed with the following message
"Remote Feature: Data Verification from /xl/worksheets/sheet4.xml-Part"
3. The drop-down lists in the complete workbook have been removed
4. The height as well as the width of the individual caves were changed

Test 2:
Save the file again on the computer 1 (* .xlsm)
Open the file under Computer 2
Again all the same as in test 1
Test 3:
The file again on the computer 1 save however this time Excel 97 format (* .xls)
Open the file under Calculator 2 = File Functional and the drop-down lists all existing
Now save the file on the computer 2 Excel 2016 (* .xlsm)
Excel close the file again and reopen the same errors as in Test 1

Does anyone have an idea for this problem? It is not just a workbook.

greeting
Todor
