in thread Using Excel in Perl failure after OS re-install

I have had a look at the Excel File --> Options -> Advanced as suggested by a Google search.
I could see anything about OLE and the settings in this section were the same for both PCs.

    Thanks to your suggestions I started looking more deeply into the Excel versions on my PC. The OS came with versions of Office which can be used for a trial and purchased.
    I deleted these (shown as Office in the apps) and then re-installed my copy of Office Professional.
    Now all works as it should!
    Thanks again.
