Hi, I did not see this thread and I opened a new one to report problems with version 1.60. I apologize for this, I think the other thread can be closed.
Anyway I have done too a clean install of version 1.60 but I continue having issues. After installation I choose Workshop6 and I click on "Train", I get this error:

Workshop6 compiling..
Error in 'default.c' line 15:
Include file ta.h not found
< #include <ta.h> // TA-Lib technical analysis functions
>..
Error in 'default.c' line 90:
Include file indicators.c not found
< #include <indicators.c> // new indicator library
>.
Error in 'line 9:
'Fisher' undeclared identifier
< vars Signal = series(Fisher(Filtered,500));
>.

Same thing on two different computers.
Other scripts that worked properly on older version don't run anymore.

regards
