I have figured the issue out now. The installation is on a x64 machine, as the Wing FTP software is running as x86 software ive had to use the x86 odbc config tool.
I found this from a post on the msdn forum, someone had a similar issue:
"DSN’s for 32bit and 64bit are stored separately in registry, those in HKLM/HKCR are for 64bit, 32bit DSN’s are stored in WOW registry.
You need to use the 32bit odbc admin tool (from windows\syswow64) to create 32bit DSN’s for your 32bit application"
Thanks for your help,
