LC Designer ES (8.1) introduced a new feature called Target Version to help you design forms for use in specific versions of Acrobat/Reader. Although new releases of Designer usually support most new features introduced in new releases of Acrobat, there are still some differences and the Target Version feature will help you ensure that your form isn’t using a feature that isn’t compatible with the version of Acrobat/Reader that you’re targeting (the version you expect the users of your form to use).
You can set a form’s target version by using the “File menu > Form Properties > Defaults > Target Version” property.
For example, the “Lock Fields After Signing” feature of digital signature fields is not supported in versions of Acrobat/Reader less than 8.0. By setting your form’s target version to “Acrobat/Reader 7.0.5 or later”, Designer would issue a warning (in the Warnings palette) about this fact if you placed a digital signature field on your form and checked the “Object palette > Document Signature > Lock Fields after Signing” box.
The Target Version Reference document (under the “Develop” tab) details the versions of Acrobat/Reader that are compatible with Designer features from version 6.0 to 8.1, incl. This should help you ensure that your forms are always compatible with the versions of Acrobat/Reader you expect your target audience to use.
