Port I/O device driver error

[David McFarlane]

Sofia,

First, just to be sure we are talking about the same thing, open up 
the Windows Device Manager (using your favorite method) on both 
computers.  Look down the tree to a branch labelled "Other 
devices".  Open that branch.  You should see a branch labelled "PST 
Port I/O Driver" on both computers.  If you do not see that on the 
troubled computer, then it does not have the driver installed.

Anyway, you probably need to repair or reinstall the Port I/O 
driver.  As it turns out, this error message and several other common 
ones are listed in PST Knowledge Base article #3000, a good reference 
for us all to look at first in the future (you will have to log in as 
a registered E-Prime user).  I don't think PST will mind if I just 
post the entry for your error, so I will spare you the trouble in 
just this case:

"The port driver is needed for read/write port calls and for using 
the Port Device. Try running a repair on your E-Prime installation 
(via the Add/Remove Programs utility in Windows Control Panel), and 
also run the PortDriverInstaller.exe file to install the port driver. 
You can download the PortDriverInstaller.exe from the User's Area by 
clicking the Download/Misc links. Then restart your machine and try 
running again (note this file will not work under Windows 98/ME)"
