Nice collection of FAQ
From the Readme file http://www.distributedfolding.org/readmeclient.html
Code:
To setup the program to work as a service:
1. Open a DOS prompt to the directory you installed the client.
2. If it is not already there, create a new file called "handle.txt" and in it
type your 8 character handle followed by Enter (or alternatively, run
foldit.bat first, enter your handle when asked for it, then quit)
3. Type: foldtrajlite /install (and hit Enter)
4. The next time you reboot your machine it will start automatically
To remove the service:
1. Go to Administrative Tools -> Services
2. Find and Stop the service called Distributed Folding Project
3. Open a DOS prompt to the directory you installed the client.
4. Type: foldtrajlite /remove (and hit Enter)
5. It will not be run on your machine automatically anymore
You may install a second instance of the service by changing step 3 above
from 'foldtrajlite /install' to 'foldtrajlite /install2'. Similarly, to
remove this second instance, change step 4 to 'foldtrajlite /remove2'.
Note that if you wish to run two instances, you must install two full
copies of the software in separate directories and install one using
/install and the other /install2. Not following this procedure correctly
will result in unpredictable behaviour.
Configuring the service
-----------------------
You should have a SERVICE.CFG file in your client directory after
following the above steps. If it is not there, remove and re-install
the service. The first line of this file must contain a number
identifying whether it is copy 1 or copy 2 of the service. Next, you
may include any of the following options in any order if you wish:
useram=1 makes use of extra RAM for improved speed (see -rt option
elsewhere in this readme); default is useram=0
priority=### where -20<=###<=20 sets the priority of the task just like
the -p option (20=passive, -20=aggressive); default is 20
progress=### where 0<=###<=100 sets the update interval for the
progress.txt file, like the -g option (0=disable)
default is 50
uploadfreq=### where 999<=###<=10000 controls the upload frequency like
the -s option; default=999=assigned from our server
