    Script error when trying to reinstall Mcafee

      Hi there,


      We have McAfee Saas Endpoint Protection 5.2 installed on two computers running W7. On one of them McAfee did not automatically update. I tried to do the "Update Now" on the icon on task bar but i got a script error. Also, i got 2 security messages on the "action center" saying that McAfee Total Protection for samll businees must be updated manually which i've already tried and failed.


      The script error is:

      An error has ocurred in the script of this page

      Line: 786

      Char: 35

      Error:  Object Expected

      Code: 0

      URL: http://vs.mcafeeasap.com/MC/VS52/InstallCore.aspx.......


      Do you want to keep running the script on this page? Y/N


      We decided to uninstall McAfee and reinstall it. I installed it by downloading an unsinstaller (mvsuninst.exe) but i could not reinstall it cause no matter what method i used (vssetup.exe. URL, etc), the installing process always gets interrupted by the script error window.


      I would really appreciate any help on this regard since it's pretty frustrating.


      Thank you!

          I have read your post.


          Please check the Internet explrer settings

          Re-register the Internet explorer script files.


          Then please proceed with the below steps.


          Click "START" and then "RUN"
          Type "CMD" and hit enter.
          Type the following commands one by one and press enter to register the script dll files.


          Regsvr32 jscript.dll
          Regsvr32 vbscript.dll
          Regsvr32 scrrun.dll


          Then after the above steps please run a Windows update from the Internet explorer-->Tools-->Windows Update. If you see any critical updates please update the computer.

            Thank you for your help but i tried that before and it did not work. Then, i found a post where they suggest to "right click" on CMD to run as administrator. It worked for registering the dll files. I restarted the computer and tried to re-install mcafee SaaS Endpoint Protection from my account by clicking on the reinstall protection button.  I still get the same scrip error. Pretty anoying! thanks anyway!

              I'm seeing the exact same behaviour on one of my machines running Vista Business. I also uninstalled and am now unable to reinstall. Registering those DLLs also did not help me. Anyone else with suggestions?

                  Hey Atmos,


                  Thanks for passing those on. I followed through those instructions and I'm still seeing the same behaviour unfortunately.


                  I've started a case with Mcafee as well, if they provide me with anything useful I'll be sure to post!

                    I have read your post.


                    Please be informed that McAfee has released the new upgraded v5.2.1 of the McAfee SaaS endpoint protection.


                    This version completely resolves the issues like High CPU usage and Upddlg.exe and sceipt errors that were occuring due to the McAfee Virus Scan software.


                    This new version is being rolled out region wise. If you want the upgrade immediately then please uninstall and reinstall the software.

                      Hello, Atmos.


                      I was experiencing the same issues installing McAfee SaaS on a client where I had uninstalled it due to the scripting error you describe.  I tried the solutions proposed in these and other forums to no avail.  Finally I decided to strike out on my own.  I am running Windows XP Service Pack 3 and Internet Explorer 8.


                      The update or installation is being driven by Internet Explorer.  I opened Internet Options and navigated to the Advanced tab.  From that tab I chose the Reset button under Reset Internet Explorer Settings.  From the Reset Internet Explorer Settings window I chose Reset.  I was prompted to restart Internet Explorer.


                      I restarted Internet Explorer and then logged in to http://mcafeeasap.com and successfully installed the software.  I had previously failed to install it at least 4 times.  It was great to actually get it working.  Of course the user lost all the settings that they had configured.  Not a big deal for me.


                      Hope this helps.


                      Best regards,
