for some reasone I am not able to make any PDF file anymore (Acrobat XI pro, Win). If file contains text or not I receive the same error message:
%%[ Error: invalidfont; OffendingCommand: findfont ]%%
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%
Here is the list of Courier font files I have in main windows fonts folder:
Please help me
Those fonts will not helpyou. You need access to the fonts which came with Acrobat in the first place. These should be in C:\Program Files\Adobe\Acrobat 11.0\Resource\Font (I think). If this has the necessary four Courier files, make sure that this folder is listed in Distiller's font locations.
A frequent cause of this is allowing a font manager to work on all directories in the system. That is not a good thing.
I have a disadvantage here, because I can only look at Acrobat X at the moment. But while you seem to have everything you need, I'm still puzzled by the CourierC files. Did you put them in there?
