Hello... I am running Win 10 64 bit. I just started having this problem. I was not running any specific game or program when it started. What I noticed was, that when I went to play Wordbiz, which I play all of the time, but this time an error window came up that says: "JET runtime has detected unrecoverable error #17 (system exception) please contact the vendor of the application. Extra information about error is saved in the jet_err_6488.txt file" When I go and try to find the file, there are no files with those numbers. So I uninstalled Wordbiz and re installed it...no change. Now there are other games that are giving me this error or simply just never load. I have not been able to find any real solutions to this problems online, so here I am asking for somebody's help with this issue.
