Unfortunately Vistrails packages are very sensitive to the Vistrails version.
With ALPS 2.2b3 you need Vistrails 2.1.2.

Dear all,

I'm having trouble installing ALPS and VisTrails on Win7. Here is a detailed list of what I did and what didn't work:

Installed VisTrails 2.2.4 from 
 https://www.vistrails.org/index.php/Downloads
Added ALPS to environment variables from control panel (it wasn’t possible to do it directly during installation, the installer complained about the "path being too long") as :
Variable Name: ALPS
Variable value: C:\Program Files\ALPS\bin
Opened C:\Program Files\ALPS\tutorials\intro-01-basics with vistrails
The program seems to initialize correctly, then I get:
Critical error: error changing version 
(I get this message twice)
The full error message reads:
 
InvalidPipeline: Pipeline has errors. Please see the detailed message for more information.
Missing package: org.comp-phys.alps

 

If, within vistrails, I try to enable ALPS from preferences/packages, get:
Initialization of package “ALPS” failed.
The full error message reads:
 
InitializationFailed: Package 'ALPS' failed to initialize because of the following exceptions:
