Thanks for aall the help folks   :D  Tried every thing , downloaded IE but would not install so deleted IE and reinstalled it but it still willnot run!!!
 The error message is displayed in a box headed  MICROSOFT VISUAL C++ RUNTIME LIBRARY does this have anything to do with the problem??
Tried the last suggestion got " installation Failed"     :cry:

Thankyou for the reply to my email 20/9 . I tried your suggestions but to no avail I am currently running Microsoft Antispyware and also Spyware blaster  ran scans on both and nothing showed so explorer still wont run , fortunatly I found a copy of Mozilla on disc so Iam running on this. Question is do I leave it at that or should I scrub Explorer and try to reload it or should I leave well enough alone.   :roll:
