Help viewer has encountered unexpected problem and cannot continue -msexcel 2007-Microsoft Help Viewer message Hi, I encountered this error when i click word or excel HELP icon ,the ? icon at the right top. I did notice that windows has updated some updates for ms office programs particularly in the help file. It has been updated and configured at the subsequent boots. But when i clicked the help file, i am getting this probelm. Other functions are perfectly working in all the office programs. I would be happy if solutions are given I have tried ms office diagnostic tool , it does not report any problem. I have uninstalled and installed office 2007, but when i click after installing the same probem persists.
