Hi, I am Probal Nag, a research scholar from IISER-Thiruvananthapuram. I am currently trying to install ALPS on Windows system by following the document on installing the binary releases on Windows. I have downloaded alps-2.2.b3 for windows followed by the required aps-vistrails module from the download page and also Vistrails 2.1.2. However, after installation, while trying to activate the ALPS module from the preference, I face an error while enabling alps. I get the error Critical message: Module Tools|MplXYPlotCell in package org.comp-phys.alps (version 2.2.0) is out-of-date. Please check with the package developer for a new version. I will be extremely grateful to you if you could help me out.
