I've fixed it by reinstall WSH which was broken by some reason. I think it will be much better that TC can tell user that WSH has issue than just no reaction. Hou u think? LeonException cannot be recover by reinstall TC8: HRESULT: -2147221164Dear Expert: While using TC8, it met exception after some system cleaning been done(I've remove some files not related to TC and done some system cleanning by 3rd party software). Below is the exception. When click Run on test script, it will not run and just give me a pass test result. When click '.' after shell, it comes up with a exception as attached file set shell = Sys.OleObject("WScript.Shell") shell. Please see details from attached file Reinstall will not fix this issue. Could you please help to find some way to fix it? Thanks a lot.
