There is no information about LANKAR requirements on its official website. I recently installed this application on my computer and I can tell you that it works right. I have a dual-core Pentium (3.00GHZ) with 4 GB RAM with WIndows 7 (64-bit). Moreover, if you have a lower performance computer, I recommend that you get in touch with the developer at: support@lankar.com and ask him the minimum requirements for this application. If you want to download this application you can choose between two versions PRO and Enterprise. The Pro version cost is: 159.00 dollars/m and the Enterprise version cost: 189.00 dollars/m.
