Install and run enigma-client:

It has been reported that users of any localized version of WinXP Pro have to edit eclient-XP-Pro-install.bat and replace "onstart".

German: "beimstart"
Polish: "przy_logowaniu"

If you don't feel comfortable editing a .bat file, follow the WinXP Home Client Install
instructions instead.



Unzip enigma-suite-winXPexe-0.75.1.zip
Change into the unzipped folder

# Edit .bat to change password
Right click eclient-XP-Pro-install.bat
Click on "Edit"
In the second line, replace "nominal" with a strong random password
In the first line starting with "schtasks", replace "nominal" with the same password
Save changes and exit
# End editing

Then run (double click) eclient-XP-Pro-install.bat

eclient-XP-Pro-install.bat performs these actions:


Tell the task scheduler not to end the process after 72h:


Goto: start -> All Programs -> Accessories -> System Tools
Click on "Scheduled Tasks"
Right-click ecrunXP.bat
Click on "Properties"
Click the "Settings" tab
Deselect "Stop the task if ..."
Click "Apply"
Click "OK"

Check if enigma-client is running:


Fire up the Task Manager:  Ctrl-Alt-Del
Select the "Processes" tab

You should see enigma-client.exe among the running processes. If you are connected to the Internet, and enigma-client.exe has managed to get a workunit, you should also see enigma.exe among them.

Log information is written to logfile in the run folder.

You're done now. If you don't want to take part anymore, follow the uninstall instructions.


Run the client on additional CPUs/cores:

You cannot run several clients in the same run folder. Thus, you have to create additional run folders:


Change into the folder "add-cpus"

In each of the XP-Pro bat files, change "nominal" to the password
that you chose in eclient-XP-Pro-install.bat.

# To create a second run folder and start a second client:
Run (double click) eclient-2-XP-Pro-install.bat

# To create a third run folder and start a third client:
Run (double click) eclient-3-XP-Pro-install.bat

# To create a fourth run folder and start a fourth client:
Run (double click) eclient-4-XP-Pro-install.bat


Repeat the "Tell the task scheduler not to end the process after 72h"
step for the tasks ecrunXP2 (ecrunXP3, ecrunXP4).


Uninstall enigma-client:

If the client is running, stop it first:


Fire up the Task Manager:  Ctrl-Alt-Del
Select the "Processes" tab
Select the process "enigma-client.exe"
Click "End Process"
Confirm the action with "Yes"
Select the process "enigma.exe"
Click "End Process"
Confirm the action with "Yes"

If you still see processes owned by user enigma-client, end them.

Remove all files created for the client:


Delete the folder C:\EnigmaClient

Remove the task from the task scheduler:


Goto: start -> All Programs -> Accessories -> System Tools
Click on "Scheduled Tasks"
Right click "ecrunXP.bat"
Click on "delete"
Confirm the action with "Yes"

Complete removal of user enigma-client only works after reboot:


Reboot
Goto start -> Control Panel
Click on "User Accounts"
Click on the account of "enigma-client"
Click "Delete the account"
Click "Delete Files"
Click "Delete Account"

That's it, there are no registry entries that have to be removed.
