A trick I learnt from someone was to compile the AMOS Interpreter program, that way problems like that can be fixed without reinstalling AMOS or having loads of AMOS config files in the S drawer
Installing extensions is easy (ish), use the attached file and do the following:
- make sure the extension (e.g. AMOSPro_AMCAF.Lib) has been copied into the APSystem drawer (found in the AMOSPro drawer)
- remove the ".txt" from the end of the name of the attached program, it's actually an executable!
- run the attached program
- select "load other configuration" and then find the file "AMOSPro_Interpreter_Config" in the "S" drawer (usually within the AMOSPro drawer itself, or possibly within the System drawer depending on your setup)
- select the extensions option (I forget the precise phrase)
- select slot 8 and check the filename matches the extension file name (e.g. AMOSPro_AMCAF.Lib) exactly
- click the top-left option (should close the current window and return to main menu)
- now click "Save Configuration"
- a confirmation message should come up about exiting AMOS for the new extension to work. Ignore it! The program is normally run within AMOS, not on it's own
- click top-left option (Quit?) to exit the interpreter setup program
- if everything was done correctly (and your version of the extension is not corrupt or hacked in any way) then AMOS Pro should work now.
