Hello David,
Thank you for your reply.
I was not aware that TSM Client 7.1 wasn't available yet for download. I based myself on the information found on this page.
http://www-01.ibm.com/support/docview.wss?uid=swg21197133#Version%207.1
So we are blocked until this client version becomes available.
Concerning Litespeed, we will need to find and alternative until a certified Litespeed will be available.
So I can asume that the future Litespeed version will be compatible with Windows 2012 R2?
Best regards,
Patrick
