Question: Unable to create mail domain using Mail Enable on 64 bit OS. Why?
This error comes in case of 64 bit OS because HC use to fetch the installation information of third party tools from Software folder in Registry Editor HKEY_LOCAL_MACHINE\SOFTWARE but in case of 64 bit OS, Mail Enable folder created under folder HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node. In order to fix this issue, please follow the steps given below:
1. Go to registry path of Mail Enable HKEY_LOCAL_MACHINE \SOFTWARE\ Wow6432Node\Mail Enable.
2. Right click on Mail Enable folder and Export it on local drive.
3. Open the exported registry file in notepad.
4. Replace all entries "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable" with "HKEY_LOCAL_MACHINE\SOFTWARE\Mail Enable" in this file. This way MailEnable key will be copied under HKEY_LOCAL_MACHINE\Software.
Note: HC started support mail enable on 64 bit OS in version HC 8 build6, version lower than this will not work.
