Thanks for your response, but my question was really is there a document which shows which versions are approriate for the relevant forms version.
So I knew that 1.10.1 was the correct version for my 126.96.36.199 and 1.14 is the version for 11.1.2 but is there a webutil/jacob compatibility matrix showing this for all versions of forms (and 32/64 bit for 11.1.2) ?
There really is no "matrix" and I don't really know that one would be necessary as there aren't that many versions of which to be concerned. There have been numerous Support authored documents which talk about how to configure WebUtil in a particular Forms environment and each mention which Jacob version to use. However, that said, the proper jacob version for a given Forms version is documented in different places depending on which versions is in question. This is because WebUtil has been an evolving add-on to Forms since Forms version 9.0.2. In the newer releases, you can find the information in the product release notes. However, here is the simple answer to your question:
Forms 9.0.4 and older with WebUtil 1.0.5 (beta) and older - Jacob 1.0.7
Forms 9.0.4 and older with WebUtil 1.0.6 (beta) and older - Jacob 1.0.8
Forms 10.1.2.0.2 - 10.1.2.3.0 with WebUtil 10.1.2.0 - 10.1.2.3 - Jacob 1.0.8
Forms 10.1.2.3+ (Forms Bundle patch) - 11.1.1.x with WebUtil 10.1.2.3 - 11.1.1.x - Jacob 1.10.1
Forms 11.1.2 with WebUtil 11.1.2 - Jacob 1.14.3
I have also added the corresponding WebUtil version above. This is important because it is also often misunderstood. Starting with Forms version 10, the WebUtil version should correspond to the Forms version. So for example if you use Forms 10.1.2.2, your WebUtil version should also be 10.1.2.2.
