Thanks Troyer, that's indeed the reason as you said. I add ALPS to the PATH manually. Best, Tao Ying 2015-10-31 12:46 GMT+01:00 Matthias Troyer <troyer@phys.ethz.ch>:

You have too many entries in your PATH environment settings, probably from other software you installed.

Dear all,

I'm trying to install ALPS to "C:\Program Files\ALPS" on Windows x64.But there is something wrong: "Warning! PATH too long installer unable to modify PATH". How can I deal with this problem?

Best regards, Tao Ying
