So when Excel couldn't find an add-in, it changed the funtion name to 'c:\program~\somedirectoery~\somedirectory'!funcitonname and this is causing me a headache. normally I would just load the addin and then find 'c:\program~\somedirectoery~\somedirectory'! and replace with nothing (if the directory path didn't just go away on it's own). I guess this doesn't work when the ~ tild character is involved. Additionally if you search only for ~ and click find all, Excel goes to IV65536??? What's going on there???
