Missing reference and “Error in loading DLL”

Question

I have an Excel tool I\'ve been building at work to automatically generate PowerPoint charts from data on Excel sheets. I\'ve been moving the project back and forth between

Answer 1

Had this issue before. My macro used the Microsoft Outlook 12.0 Object Library and was designed to work with that for all users of the team. However since an update to Office 365 was planned one of the IT guys had opened the macro with the new Office 365(and Microsoft Outlook 16.0 Object Library was set to be used). After this all of the users had:Error in loading DLL on their screen as they were still on the old Office 2007 and the new library Microsoft Outlook 16.0 Object Library was in the References list. Tried in vain to unselect the new one and select the old library.

My solution to this issue:

1. open a new excel file(not a macro)
2. go into the Ribbon(office 2007 & 2010)->Excel Option->Trus Center tab->Trust Center Setting button->Macro Settings
3. select option: Disable all macros with notification and then click Ok button
4. Close the Excel file opened(not the excel window) - from the lowest X on the right corner
5. Open the macro using the Ribbon and then option Open
6. Get into the dev mode(ALT+F11) and go to Tools->References then unselect the broken Excel library(the one with MISSING:)
7. Select the correct library from the list and click OK
8. Save the macro and then close it.
9. Revert the selection done at step3 to option:Enable all macros and Voila!
