Got Vanguard CapChart installed on 3 machines, all Windows 7 64-bit. Whenever anyone tries to import an Excel file, we get an error "The 'Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine." (The actual OLEDB number is variable, depending on the Excel file). I've tried setting the application Pool (there's only one for any of these machines) to enable 32-bit applications, and rebooted, but I still get the same error. There's no 64-bit version of JET that I can find, and installing a substitute won't work without removing the 32-bit versions of Microsoft Office, which I don't have the authority to do, and can't get anyone else to consider. Any ideas on how to make it compatible, or can I get a 64-bit version?
