I had the same problem with 2 applications developed by me since 3 years (c# and java). Since 10-oct-2017 I couldn't export to excel 2003 but 2007 worked, and couldn't import from excel 2003 but 2007 worked too for import.

Temporally Solution: uninstall KB4041693, KB4041687 in windows 8.1 (maybe for w10).
In microsoft changelog of both path say something about "updates [...] and security updates for microsoft jet". After uninstall and restart all softwares becomes to be normal again.
this problem was introduced in 10-oct-2017. In microsoft forums this problemas was reported (kb4041693 should "fix" it but still doesn't work). Maybe in few weeks they will path (properly) this issue.
