- Purchase the Microsoft Access Developer's Toolkit (ADT) version 2.0 available through resellers or direct from Microsoft by calling the Microsoft Sales Information Center at 800-426-9400. The suggested retail price is $495 for new users. However, until August 31, 1994, owners of Microsoft Access Distribution Kit version 1.1 and Visual Basic version 3.0 will receive $100 off price via a rebate. All the files you need, including the Jet 2.0 database engine, are included in the ADT.
- Purchase the Microsoft Office Developer's Kit (ODK) and Microsoft Access version 2.0. Both products are available through resellers or direct from Microsoft by calling the Microsoft Sales Information Center at 800-426-9400. The suggested retail price for the ODK is $99.95. However, if you own Visual Basic version 3.0 Professional Edition, you can get the ODK for only $49.95 by calling the Microsoft Sales Information Center at 800-426-9400.
The ODK will also be available as a standard component in all new packages of Visual Basic version 3.0 Professional Edition. The ODK comes on CD-ROM only.
The Compatibility Layer that you download from the MSL or that is included in the ODK does not include the Microsoft Access version 2.0 (Jet 2.0) database engine file. The 2.0 database engine comes with Microsoft Access or the ADT. Therefore, to use the Compatibility Layer, you need to purchase Microsoft Access version 2.0 or the ADT. The license in the ODK permits distribution of this file with Visual Basic version 3.0-based applications. Suggested retail price for Microsoft Access version 2.0 is $495. Until August 31, 1994, current Microsoft Access version 1.x users can upgrade for $99. And those users upgrading from competing products and from Microsoft Office can purchase Microsoft Access version 2.0 for $129.
