I recieved the following error The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine on my Vista 64 bit machine today. I made no code changes since I run it on a 32 bit OS.
Aparantly there is not a 64bit Microsoft.Jet.OLEDB.4.0' provider and you have to force your build to 32 bit.
In the settings for the project under the Build Tab you must set Platform target to x86 instead of Any CPU
