It's that kind of thing that usually forces me into SSIS. And at times, when even SSIS balks, back to VBScript. Push comes to shove, an install of Excel on the target machine, if not already there, may have an impact.
I can tell you that I'll never allow Excel to be installed on a production server and I don't care if it's the CIO, CEO, or anyone else saying "Just do it". 😉
Don't install Excel/Office, just the ACE drivers, which is just another provider.
