Lotus Notes 8.5.1 vs SEP 12.1 RU1 MP1 nlnhook.exe
i want to inform all outside, we´ve yesterday solved/get a workaround to the known issue/problem with nlnhook.exe in combination SEP 12.1 RU1 MP1 und Lotus Notes 8.x
(only for Windows 7 Client, could also work on Windwos XP)
removing the notes.ini file from c:\programdata\lotus\notes\data folder and restarting the machine. (can done via gpo)
You will no longer get the app crash error.
it´s working fine for us, and Lotus Notes works without issues
hope also working for anyone other outside
