> Hello to every Formers. days ago I’ve read on forum that someone could be interested into older versions of PreForm software. I’ve update on a free hosting website the old versions of the FormLab printer (for Windows only). I’ve collected them till the version 0.9 (sorry, maybe I’ve missed some releases) PreForm 0.9.0: [http://www.mediafire.com/download/jt248x5v1cfuiei/PreForm\_0\_9\_0.exe](http://www.mediafire.com/download/jt248x5v1cfuiei/PreForm_0_9_0.exe) October 2013.

You’ill find what you are looking for in these posts.

If you use your Form for critical work in general or if you have critical work to be done in the short term, I would advise you to not update neither preform or the printer unless you really need to (new resin not supported by older version is one reason).

If it ain’t broke, don’t fix it … it’s a dangerous saying at times, but it applies in this case IMHO. Formlabs is doing a great job with updating the software capabilities of Preform and the Form2, they just don’t seem to have enough workforce or time to thoroughly vet new versions… better to let other users who can afford it to test the stuff.
