As the error message indicates, the problem may be due to a corrupt registry or incorrect permissions to write to the registry. In addition, the problem occurs on computers running Windows 95 when the Setup program tries to add an entry to a registry key and the key will exceed 64K in size as a result. Registry keys are limited to 64K in Windows 95.
