Look at the error message. It tells you hat you need to enable the control flow and vtl creator packages first.

Thank you for your reply.

I have been trying to enable the ALPS in vistrails preferences->module pachages->disabled packages->alps, but it cannot be changed, alps is still in disabled packages.

You need to enable those packages in VisTrails before enabling ALPS

Dear ALPS members and developers:

I have been trying to install ALPS 2.1.1 (Binary package) on windows 7 (32-bit) and Mac OS X 10.6.8 (64-bit), but I met same problem when I open VirTrails:

CRITICAL

2013-01-03 12:00:29,721

/Applications/VisTrails/VisTrails.app/Contents/Resources/lib/python2.7/core/packagemanager.py, line 501

Dependencies of package ALPS are missing so it will be disabled

Package 'ALPS' has unmet dependencies:

edu.utah.sci.vistrails.control_flow

edu.utah.sci.vistrails.vtlcreator

I will appreciate if you could help me fix the problem.

Best regards,

Ben LI
