Below is my wild guess based on my working on WIndows 7 and VISTA.
In Windows 7 there is an restriction of Creating files. if you notice your client might not be able to save any excel or word doc to C:\
It might throw error of Access.
Similarly when we open the IE to access Qlikview, there are temp files which gets created in USerprofile/Qlitech\Qlikview (I am not sure about the exact path in windows 7). hence the application is trying to save it might be throwing an error.
You can avoid this by reducing UAC (User Access control). You will find it in User account.
Test first this by creating excel or word and try to save it to C:\.
I hope this helps you out.
