Error 0x80004005 just means "Access is denied". In Vista, and so probably in Win 7, you need to run "regsvr" command from an elevated command prompt, hence the requirement to right-click on the icon and select Run As Administrator. Is that what you did?
There is a thread about this problem on Mcrosoft Answers, with a description of how to fix it, HERE.
Yes, have tried running the prompt at administrator, and am still getting the same error message. Have run the other command regsvr32 vbscript.dll with no problems, but the jscript prompt is not a happy bunny.
Have done through the thread you suggested and tried running sfc/ scannow to check and resolve problems, no integrity violations were found, but I am still unable to run the jscript prompt successfully.
Can anyone help with this problem?
On the wife's machine what version of IE is installed? (Open it and go to Help/About). If IE8 please update to IE9 and try again or if IE9 beta or RC versions please uninstall and then install IE9 final version and then retry.
Do this regardless of the default browser preferences.
Also it should be Windows 7 SP1 now and here's help with installing the Service Pack: https://community.mcafee.com/docs/DOC-2205
The laptop is running IE9, so I am going to do as you suggested now that my 2 year old and 4 month old baby are asleep and I can carry on trying to sort this sodding problem out in a little bit of peace. And have a look at the service pack too.
Try opening Internet Explorer and going to Tools/Internet Options/Advanced and click Reset. Click Apply and OK any prompts.
Close and reopen the bowser and go to Tools/Manage Add-ons and re-enable any you need.
It's not that easy to troubleshoot these things exspecially as jsript and Java are two different things really.
See if that helps.
