[Wine] Error 3: path not found

[cyberlinus]

O.S. Linux Ubuntu 8.04

I am trying to install Banana 5 accounting, following the SW manufacturer instructions (http://www.banana.ch/cms/en/linux_installation)

I have downloaded the .exe file, but when I try to open it with Wine, I get the following error msg:

"Not possible to create folder "C:/windows/is-7DK.tmo
Error 3: path not found"

I guess there is something wrong in the Wine configuration, I tried but I can not find how and where I should direct the installation to a different path.

Many thanks in advance for your help.
