Parallels Panel uses MailEnable x64 edition installed in the system as the Mail server component.

How to switch MailEnable services from using 64-bit binaries to the 32-bit ones?


1. It is necessary to determine the MailEnable installation path. One of the possible ways - via Windows registry, by the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable\Mail Enable key. The Program Directory parameter can point to the folder. Another way - using of the following command:
sc qc memtas | findstr /i memta.exe
          BINARY_PATH_NAME : C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin64\MEMTA.EXE

It can show the path of the 64-bit binary files which are used for the Mail server.

2. Then it is possible to use the following commands to reconfigure the MailEnable services (replace the "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable" path before with the determined during the previous step):
sc config memtas binPath= "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin\MEMTA.EXE"
sc config melcs binPath= "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin\melsc.EXE"
sc config mepocs binPath= "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin\mepoc.EXE"
sc config mepops binPath= "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin\mepops.EXE"
sc config mesmtpcs binPath= "C:\Program Files (x86)\Parallels\Plesk\Mail Servers\Mail Enable\Bin\mesmtpc.EXE"
