  1. Do you know if the converter will work with a student version?
    I have original CDs with packaging, keys, etc. of LT 97, and 2000i.
    My goal is a simple drawing of a kitchen remodel, likely a one time event, so don’t want to invest too much.
    The converter does seem like a good fit if works.

  2. Hi.
    I bought you the Longbow Converter software in December 2016 to be able to work with Autocad LT 97 on a Windows 7, then 10, version.
    Everything worked fine until recently when Windows 10 updates destroyed orders inside Autocad. For example create a block, save as, export.
    I plan to reinstall Autocad LT 97 with Longbow Converter.
    My question: should I uninstall the old installation or just install again without taking care of the old one?
    Thank you for your reply.
