64 bit or 32 bit? and Microsoft access also?

[Irishmist]

I built a powerbi report and it worked several times refreshing data from same excel source files. Then I get an error saying something about 64 bit not matching... so I followed the link to microsoft site that said needed to match 64 bit if that's what my computer needs... so I uninstall P-Bi and reinstall 64 bit version and it still won't work.. so i read it again and install Microsoft access 64 bit and still does not work... so I uninstall both p-Bi and access and reinstall both 32 bit versions and get another errror - the External table is not in the expected format.... so here I am...

How can I check if my Office is 32 or 64 bit?

thanks

FYI - mine was not 'XY_Create.mdb file shown above- mine was an excel file but I copied another users error statement as everything else was identical

 First error was - Microsoft Access: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. The 64-bit version of the Access Database Engine 2010 Access Database Engine OLEDB provider may be required to read 'XY_Create.mdb'.
