First thank you Dominic Price for porting Cadabra to Windows and Kasper for writing Cadabra.
Second I have not been able to make it work on my Win 10 64bit machine yet.
This is what I did:
Installed latest MikTex, replacing an older version. It is working fine
Installed Anaconda 3 .It is working fine (1+1=2 using several editors).
Downloaded Cadabra 2.2.0 and Cadabra 2.2.1 from this site.

Cadabra 2.2.1 installs fine , but as soon as I load beginners.cnd I get a generic TeX error dialog box, with no further explanation.
Same thing as soon as I try to evaluate any cell that I write.

Cadabra 2.2.0 does not even install. It stops during installation saying sqlite3.dll is missing.

Any suggestions?

... didn't change behavior

(deactivated speech recognition, could have "occupied" input fields)
(Cortana starts again after stopp it's processes)

I used process explorer to get an idea what's going on in Windows 10. The proceses of Cadabra became red aifter 2 seconds and vanished. After that "runDDL32.exe" was visible in red for a second, which surprised me, because i thought i was running a 64-bit version. I realized, that i installed the first version named before anaconda python and that was 32-bit. I deinstalled Python 3.7.0 and installed Anaconda 3.6 for Windows. The Firewall asked for permission and now it seems to work ...

Ah, very good, thanks for getting to the bottom of this.

Text from installer:

Before installing Cadabra2, you must make sure that the following prerequisites are satisfied:
* A working Python installation
You must have python3 installed on your system with the sympy package available. Python can be downloaded from https://www.python.org/downloads/ and sympy is installed by executing the command ‘python -m pip install sympy –-user’. Alternatively, use an Anaconda Python installation, available from https://www.anaconda.com/download/ .
* A working LaTeX distribution
MixTex is recommended and can be downloaded from https://miktex.org/download - this is the largest dependency.

Better only mention Anaconda Python ?

Yes, we didn't quite understand the mess that the Python ecosystem is in when it comes to incompatibilities. It should mention that you absolutely need a 64-bit Anaconda Python.

Please try the 2.2.1d installer which is now available, and let me know if that's any better.

Thank you Kasper.
It works for me now, although it had some kind of glitches the first time I tried it.
Always related to the Latex printout.
I think my Latex install is not perfect/complete (I use LyX 2.2 on Win 10).
Anyway it works for the most basic situations like trying the tutorials.
Sorry for the delay in answering you.
