Went to update McAfee Internet security on family laptops today, all went fine on mine. All went pearshaped on wife's. She has an Acer aspire running Windows 7 home premium. Basically the current McAfee will not open whatsoever, you just get a nice blank white screen. It cannot be unistalled as again you just get a blank white window. When trying to install McAfee 2011 she gets an error message saying
"Installation Cannot Continue
So, we did the sensible thing and googled the problem, found responses in the discussions on here telling people to
click on the start button(windows logo on Vista)
on the field "start search" type "cmd" without the qoutes, an icon will apear on the top part.
right click on that icon then select "Run as Administrator"
type "regsvr32 jscript.dll" without the quotes on the black window that will apear then press Enter(A message will appear confirming that the process was succesful) Restart your PC then try to download McAfee again.
Unfortunately, she just gets the error message
"The module jscript.dll was loaded but the call to DllRegisterserver failed with error code 0x80004005.
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.Message was edited by: Hayton on 28/07/11 23:52:49 IST
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.
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.
