Just got a little issue with some of my users today, when trying to open an email attachment in Lotus Notes, they get the error Unable To Invoke Program. Now, they can always just save the attachment and then open it through windows explorer, which is fine, but I would rather get a proper solution for this.
Knowing almost nothing about Lotus Notes does not help me I know but I think it may have something to do with the default file association, however my colleague tells me that Notes uses the windows file associations, which are working.
Any ideas anyone?

Try deleting (backup beforehand) the Cache.NDK file (while notes client is not running).
Other then that, determine at what point did it stop working? If you recently migrated from an earlier version you can try running the NICE utility. Details are here.

Make sure you have backups of the important files in the Data folder before running it though.
