To install eTransmit on a Windows Terminal Server or Citrix Metaframe, proceed as you would with any other application. After the program has been installed, you must deal with the Crystal Reports files that are added by eTransmit.
Crystal Reports uses a folder called CRYSTAL that is under the WINDOWS or WINNT folder. This folder is where Crystal Reports puts various drivers and export DLL's for the whole system. This is meant to be a system wide folder but due to Terminal Server/Citrix's ability to share the WINDOWS/WINNT folder with multiple users, the system cannot find the CRYSTAL folder files without additional configuration.
There are many methods of addressing this issue with Crystal Reports. Crystal Decisions recommends in a technote that you copy the CRYSTAL folder files to the folder of the application (ACCPAC's RUNTIME folder). Or you can copy the CRYSTAL folder files to a CRYSTAL folder under each user's private WINDOWS folder. Another method is to copy the CRYSTAL folder files to the SYSTEM32 folder.
You will need to decide which method is appropriate to your installation and implement it in order to run ACCPAC Advantage on a Terminal Server/Citrix machine. Once you have installed eTransmit, you will need to repeat the procedure you used for the CRYSTAL folder files because the eTransmit install program adds new files and updates other files in the CRYSTAL folder.
