The server is a new build, so there were no other RichHelpTip DLLs. I followed the dirctions you gave above for looking at the DLL version and got the following result:
"RichHelpTip Developer v2.0 Build 1"
I had downloaded an eval copy of the RichHelpTip component to my development laptop and thought that perhaps I had mixed the two up and was copying the eval DLL to the server. However, a coworker (who we also got a license for) never downloaded an eval copy (only his purchased copy) and his Dll/License code has the same problem of working on his development laptop, but not on the server.
One sort of odd thing, is that we purchased our components in late January when I believe you were in the process of upgrading the components from version 2.0 to 3.0. When we purchased the Suite, all of the components were version 2.0 except for the RichTextBox which was version 3.0 (ie: our license codes are all for 2.0 except for the text box which is 3.0). Oddly enough, it is the RichTextBox component that does work on the server. Is it possible that the license files we were sent were also intended for 3.0?
Is it possible for me to forward to you the email that we received with our license codes and then have you email us back a RichHelpTip DLL that we can be sure works with that license code and then we can go from there?
