ACC2: OLE 2.02 Required to Use Custom Controls (123593)

SUMMARY

Advanced: Requires expert coding, interoperability, and multiuser skills.

OLE controls created with the OLE Control Developer's Kit shipped with Microsoft Visual C++ version 2.0 require users to install OLE version 2.02.

Trying to register such a control in Microsoft Access will cause the following error message:

Insert Object: <OLE Control> was unable to add itself to your system. Install the control using a separate setup utility.

Using a utility such as REGSVR.EXE or MSAREG.EXE will result in the error message:

DllRegisterServer in <OLE Control> failed.

MORE INFORMATION

To use OLE controls created with the OLE Control Developer's Kit with Microsoft Access, install OLE 2.02.

OLE 2.02 is available with the Microsoft Access version 2.0 Service Pack. For information about how to obtain the Service Pack, please see the following article in the Microsoft Knowledge Base:
