[Wine] Circuit Design Suite installation

[Giorgio]

I download Circuit Design Suite from National Instrument site and I tried to install it.
The file downloaded is NI_Circuit_Design_Suite_10_1_Education.exe of 304 MB.
I simply open Dolphin and double click on it. It start asking for unzipping, then installation starts.
After a while I get this error message http://img181.imageshack.us/my.php?image=grana1is3.png

But I check and I find the directory requested /home/giorgio/.wine/drive_c/windows/profiles/giorgio/Miei Documenti
Is it a problem with permission ?
