The Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine
Amphis Customer is designed to work on 32 or 64 bit PCs running Windows XP, Windows Vista, Windows 7 or Windows 8 Pro, but on Windows XP 64 bit (and possibly other operating systems) it is possible that some of the Microsoft OLEDB DLLs have not been registered.
The Solution No. 1. :-p
The solution is to manually register those DLLs.
go to Start->Run and type cmd
this starts the Command Prompt
(also available from Start->Programs->Accessories->Command Prompt)
type cd .. and press return
type cd .. and press return again (keep doing this until the prompt shows :\> )
now you need to go to a special folder which might be c:\windows\system32 or it might be c:\winnt\system32 or it might be c:\windows\sysWOW64
try typing each of these eg
(if it says The system cannot find the path specified, try the next one)
when one of those doesn't cause an error, stop, you've found the correct folder.
now you need to register the OLE DB 4.0 DLLs by typing these commands and pressing return after each
Solution No. 2 :p
To resolve this issue open the project in Visual Studio then:
1. From the solution explorer right-click your project then click Properties
2. Click the Build tab
3. Change Platform target from: Any CPU to x86
4. Re-build your solution
