Can't install: Some tmp file is missing.

It tells me that a tmp file is missing so it can’t install.  The file is in Doc/Settings/me/Local Settings/Temp.  Using XP 32bit SP3.  Anybody else have this problem?  Have tried it 5 times.  

The ExpressCache software is not compatible with XP. Only Win 7 and Win 8
