@telatoa We don't support Crossbar on Python 2 anymore, please try installing using Python 3.

Hi,

We still use 2.7.15 Python version as it's the last release with an MSI file (used in an InstallShield project), isn't?

[om26er]

yeah, I just opened https://www.python.org/downloads/windows/ and it seems that's true.

[telatoa]

Ok so what's the solution?

[oberstet]

please use python 3 - as mentioned, python 2 is not supported

we also have crossbarfx upcoming, an extended version of crossbar with more features under commercial license, and for that we produce ready-to-run binaries, including for windows. if you are interested, you can give the alpha a try:

windows 64 bit: https://download.crossbario.com/crossbarfx/windows-amd64/crossbarfx-latest.exe
windws 32 bit: https://download.crossbario.com/crossbarfx/windows-x86/crossbarfx-latest.exe

to start, instead of crossbar start do crossbarfx edge start

this executable has everything bundled - you don't need anything else installed (no python needed)

Ok thank you for your reply.

I created an new request in Python project in order to have the Windows x86 & 64 MSI installers for latest Python Releases #1382
