Lotus Organizer on Windows 10 cannot load "LTBUBN12.DLL"

Hello TrevorEH

Welcome to Microsoft Community.

Regarding to your information I assume that you lose your .dll files after the updating.

The .dll files will lose by many reasons like the name changed be deleted the version not right. You can get .dll files in network or reinstall the software

or like the solution like you copy from other computer.

If there is anything not clear, please do not hesitate to let me know.

Thanks, but the DLL files are there.

I've seen the same message, so I did some experimenting

I discovered that if I run org6.exe from its installed location rather than using a shortcut, Organizer will still run. Organizer generates this DLL message only when I try to run Organizer from a shortcut. Not sure why this should be

Thanks Rich; I have Org5 and I tried this prior to my original post and it does not work. The Organizer program opens and I get the Lotus Organizer solid green window, but it will not open a file. I have the original Lotus programs disk and it will not open or install on Windows 10; it will not read the disk.

Thanks again,

Trevor
