Can anybody help me please?

A few days ago, my MS Word 2002 started to play up, I kept getting a visual basics (??) warning box pop up and then the program would become very unstable.  I uninstalled it and later uninstalled the entire Works Suite 2003 and  can't now reinstall Word.  Midway through installation it comes to halt and I get the following message:-

Error 1311 - Source File not found:E:\OFFICE1.CAB.  Verify that the file exists and that you can access it.

I have run Norton Disk and Windows Doctors in the hope that they  would identify and remedy the problem, but no luck.

I really dont know where to go from here, I've tried the MS help web site but I can't find the answer there.

I would appreciate your help.  Thanks

Kelv.
