Error Code 1002: The License Key you entered is incorrect, please try again (this error code means you have entered an invalid license key or that the key does not exist in our license server)

Error Code 1003: This License Key has already been activated, please try a different License Key (this error code usually means the license key you are trying to activate is currently activated on another server, please use the transfer option available inside your account)

Error Code 1004: This License Key has been disabled, please contact echoPANEL support department (this error code usually means there is an ownership conflict, please notify us through the support centre)

Error Code 1005: You have attempted to install a newer version than you are entitled to, please contact echoPANEL support department (this error code usually means the version you are attempting to install is newer than your license key permits, please use the upgrade option available on the purchase page)

To do this, open DRIVE:\Program Files\Sanamato\echoPANEL\App\Root\ Includes\identifiers.txt and follow the instructions at the top of the file.

If you are experiencing problems, you can confirm Serv-U configuration parameters as follows;

• To check if Serv-U is running as service, open Serv-U Administrator, highlight your server in the left pane, and in the right pane there should be a check in "Start automatically (system service)"
   
• To check how Serv-U is storing its domain settings, open Serv-U Administrator, highlight your domain (below Domains) in the left pane, and in the right pane the Domain type should be "Store in computer registry"

If the above settings are correct but you are still having problems, it is very likely due to having more than one domain in Serv-U.

There is a thorough help topic regarding this in the official SmarterMail Help documentation located here.

If SmarterMail is running under IIS but you are still having problems, check the following;

• Ensure you have stopped and disabled the SmarterMail built-in web server
   
• Ensure the IP Address shown in IIS is not 127.0.0.1
   
• Ensure you have entered the correct information below the Basic Settings tab, on the echoPANEL Settings page

Given the variety of firewalls on the market, we cannot explain how do that here, but it is generally a simple task and should be outlined in your firewall documentation.

To do this, click on Start > All Programs > Administrative Tools > Services and look for Windows Management Instrumentation, then confirm the service is Started and set to Automatic.

• There is a unique Identifier mismatch, see article KB1003
   
• You have more than one FTP Site (you only require Default FTP Site)
   
• The FTP Site in IIS is stopped

• Passive Mode is interfering with the connection, and may need to be disabled
   
• You are not using the correct IP Address, username or password

• Uninstall echoPANEL from the Windows Start Menu, and re-install your previous version using the correct echoPANEL.exe file (recommended)
   
• If for some reason, you cannot or do not wish to use the method above, you can perform a similar operation by replacing the new files manually. To do this, you will need to be logged into your server with administrator rights, where echoPANEL is installed

1. Logout of echoPANEL, and close your browser
    
2. Open C:\Program Files\Sanamato\echoPANEL (this only applies if you selected the default path during the installation)
    
3. Look for a folder called Backup
    
4. Inside the Backup folder, open the backup_date folder where "date" reflects the most recent date
    
5. Copy everything below the backup_date folder
    
6. Move back up to the C:\Program Files\Sanamato\echoPANEL folder and paste, overwriting the existing files

Use the second method described above only as a last resort. In most cases this will work fine, but could cause undesirable results. Use at your own risk.

Regardless of which method you choose, any Websites, Email Accounts or FTP Users created while the new version was installed will be not be visible in echoPANEL when you revert back to the previous version, and it may be necessary to manually delete them from IIS, your mail server, and your ftp server to prevent duplication problems.

1. Open IIS, click on Web Service Extensions in the left pane, and confirm that ASP.NET v1.1.4322 is visible and Allowed, in the right pane view.
    
2. Open Windows Explorer, and navigate to C:\WINDOWS\Microsoft.NET\Framework and look for a folder called "v1.1.4322".

If the .NET Framework is not installed, the preferred method of installation is through Windows Update but if for some reason, you cannot use this method, it can be downloaded directly from;

.NET Framework 1.1
http://www.microsoft.com/downloads/details.aspx?FamilyID=262d25e3-f589-4842-8157-034d1e7cf3a3&DisplayLang=en

And the latest service pack, after the above installation, can be found at;

.NET Framework 1.1 SP1
http://www.microsoft.com/downloads/details.aspx?FamilyID=a8f5654f-088e-40b2-bbdb-a83353618b38&DisplayLang=en

There has likely been an ASP.net 1.1 failure to copy the MailEnable DLL to the correct folder during the MailEnable and/or echoPANEL program installation.

There are two possible methods to fix this;

1. The quickest and safest is reboot your server
    
2. If the first option does not solve the problem, open IIS, and switch the .NET version of the echoPANEL website to .NET 2.0, save, then switch back to .NET 1.1, and save
