Version 10 accesses handifiles folder and not temphandi. so not sure what is going on. Anytime you clear out everything and restart install, you need to take a word processor, open analyst.flg and make sure there is a capitol T on the first line and not a capitol F. Then make sure the two files that are available for download are in handifiles folder. The application files can be in any other folder. Once you open the app, it creates files in handifiles folder that you need.
Then follow the guide and complete the steps and you should be able to get going.
