1) Just go to 
C:\Documents and Settings\YourName\Local Settings 
(note: Local Settings could be a hidden file which you need to be able to view first) 
Then uncheck read-only under property for 
"Temporary Internet Files" and "Temp", thus changing all the subfolders and files properties. 
2) Then go to Tools->Internet Options->temporary internet files -> settings 
to set a reasonable amount - say 300MB of space for temporary internet files folder.
