By Paul - Wed 20 Jul 2016 What version of windows are you running on the server? What is the latest version of .NET you have? By SAbow - Thu 21 Jul 2016 the server is Windows 2008 R2 Standard Edition. 4.5.2 is the .net By Paul - Fri 22 Jul 2016 Those should be fine to support TLS 1.2 and also to run the latest Kartris paypal DLL. Have you installed that? If you got any errors, were they the same or different? By SAbow - Mon 25 Jul 2016 Where would I find the paypal.dll - I did not see an individual paypal.dll file in the bin I did upload the latest paypal.dll to the bin folder and I got the same error. is there a special way to "run" the paypal.dll? Please let me know. By Tiggywiggler - Mon 25 Jul 2016 It is simply a matter of copying it from the Plugins/Paypal/ folder and then pasting it into your application, no other work.
