If you have problems installing the software from a CD, follow these steps:
At a command prompt, enter the SET command and see what it says for TEMP=.
Look in the directory specified in TEMP= and see if there are any subdirectories whose names begin with PFT or _IS.
If there are directories with names which begin with PFT or _IS, and if you are not running an installation, delete those directories because they can cause installation errors if they exist before you run an install.
Most installations create these directories and remove them when finished. If there is a problem or if the operating system is too busy managing other temporary files, these directories may not be deleted in a timely manner.
