Vista - Microsoft office and adobe problems

  celestialstar 21:22 16 Oct 09

I am having problems with Vista Home Premium on Dell Laptop. Suddenly all word and excel docs are saying incorrect file ext or format. Also cannot open Adobe files - corrupt files??

Along with this unable to update microsoft updates error 646.

Cannot restore as only have todays dates, don't know why as have not deleted any restore points.

Will I have to reinstall Vista?? Any suggestions welcome. At the hair pulling stage now

Have now managed to down load updates except for vista SP2 after deleting various documents

I keep getting a request to install 1 update on close down. After trying to manually install update, I am now getting Error Code 646. Have no idea what this is, any ideas on resolving this would be most welcome. Thanks
