I build a solution to download an Service Desk 4.5 Attachment, and it works fine.
After that I install Service Pack 17 and the Download does't work... I see Service Pack alter very mutch the struct of SD attachments. Anybody know how can I get the total path of a attachment, to be possible download the file?
If your previous version was SP15 or lower, you need to run mig_attachment.pl to update the attachment folder structure, which changed drastically after SP16. You should find information regarding this in the itsm007474 folder of your SP17 download, including the logic behind the new structure.
Otherwise, can you attach the error you're getting?
