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.
