Hi Bruce,

you need
- a recent development snapshot from github
- to specify the full path to luatex.exe, like pdftex-path "C:/Program files/Therion/bin/windows/luatex.exe"

From my query two weeks ago, and Martin’s suggestion I try LuaTeX…

I’ve edited C:\Program Files\Therion\therion.ini to include… pdftex-path  "luatex"

 

I’m missing something:

Running my thconfig with Mapiah, I get a log file that ends with…

 

making map ... done

'luatex' is not recognized as an internal or external command, operable program or batch file.

C:\Program Files\Therion\therion.exe: error --Press ENTER to exit! pdftex exit code – 1

 

Running my thconfig with XTherion, there is no mention of Luatex.  I get a log file that ends with…

 

##################### end of pdftex log file #####################

C:\Program Files\Therion\therion.exe: error -- pdftex exit code -- 1

writing xtherion file ... done

 

I checked my %APPDATA%\ folders, and the only Therion related ini in there is Loch.ini

Any ideas?

Bruce
