Here's the one I keyed off of:

The problem with the third solution, at least for me, is that I experienced the same perplexing problem as you. That is I fiddled with the permissions, signed onto a non-admin account, and it might work once. The next time it wouldn't!

Basically, here's what I tried before I had to attend to something else:

1. Changing the permissions in the hierarchy of folders C:\WINDOWS\twain_32\EPFB5\ES0007 (as per the Kurzweil site)

2. Changing the run permissions of the programs in the folder C:\WINDOWS\twain_32\EPFB5

I suspect, TWAIN is creating or accessing a file (temporary?) somewhere else.

I'm stuck until I find some more free time.



I don't have those exact options on XP Home so I tried something I got on an MS forum relating to another program - tip supplied by Michael Bednarek http://mbednarek.com/ - seems to be very helpful for those programs that won't work in User accounts.

When logged in as administrator navigate to relevant directory and from a command prompt execute following command
cacls . /e /g Users:f

which grants write priveliges to all users for NEW files only

If that doesn't work, you can extend it to ALL files in the folder with the command
cacls *.* /e /g Users:f

This seems to have allowed me to use the Twain interface in a User account. Phew!
