I am at the end of my rope with this. I've been asked to install a Fujitsu fi-5120c scanner onto a Windows 7 Pro workstation. I downloaded the most recent driver from the Fujitsu website and run the install as Administrator (I've run it as the admin of the workstation and as domain administrator). The installation process creates a directory \%windir%\twain_32\fjscan32\ and places into that directory a number of files. One of those files is named FJTW32.wrp. I've been told by Fujitsu tech support that when I plug my scanner into the workstation's USB port, their software is supposed to make a copy of that file and rename it FJTW2500.ds. When we go through the normal install process that file does not get created.
SO, Fujitsu said, "No Problem Man! We'll just create the file manually and you'll be fixed!" So we manually copy FJTW32.wrp to FJTW2500.ds, reboot the computer, look to the directory expecting to see the file and IT DISAPPEARS.
We've removed antivirus from the machine thinking that maybe it was removing the file. No joy.
Nothing I can do causes that file to not be deleted. I have changed ownership and modified permissions to deny deletion, but the file just keeps getting deleted.
I have also completely disabled UAC on the machine thinking that would solve matters... but no go.
I also created a dummy file called testds.ds (a zero byte file) and placed it in that directory. After rebooting, that file too had been removed.
I CAN, however, create file like readme.txt in that same folder, reboot the computer, and find that the txt file still exists.
