> Examples please! Ok. First from inside Wine just after an attempted install to the destination home directory of "c:\oracle\product\10.2.0\client_1\": Code: C:\oracle\product\10.2.0>dir Volume in drive C is Volume Serial Number is 0000-0000 Directory of C:\oracle\product\10.2.0 3/8/2009 10:56 AM <DIR> . 3/8/2009 10:56 AM <DIR> .. 3/8/2009 10:56 AM <DIR> client_1 0 files 0 bytes 3 directories 6,748,340,224 bytes free C:\oracle\product\10.2.0>cd client_1 Access denied C:\oracle\product\10.2.0>copy c:\test.txt c:\oracle\product\10.2.0\client_1\test.txt Access denied C:\oracle\product\10.2.0> And then from the Ubuntu command prompt: Code: nathan@bignathan:~/.wine/drive_c/oracle/product/10.2.0$ ls -l total 4 d----wS--- 3 nathan nathan 4096 2009-03-08 10:56 client_1 nathan@bignathan:~/.wine/drive_c/oracle/product/10.2.0$ cp ~/.wine/drive_c/test.txt ~/.wine/drive_c/oracle/product/10.2.0/client_1/test.txt cp: accessing `/home/nathan/.wine/drive_c/oracle/product/10.2.0/client_1/test.txt': Permission denied nathan@bignathan:~/.wine/drive_c/oracle/product/10.2.0$ And additionally, from the end of the log the Oracle installer creates: Code: ... INFO: *** Install Page*** INFO: FastCopy : File Version is Compatible INFO: Install mode is fastcopy mode for component 'oracle.client' with Install type 'Administrator'. INFO: HomeSetup JRE files in Scratch :584 INFO: OUI-10125:Unable to write into the Oracle Home you have specified. I can manually reset the permissions after the fact with chmod, but that doesn't help because the installer just removes the permissions again the next time I run it. And I did try installing it to a FAT partition from Wine, but that didn't help as the installer still thought it was NTFS and tried to set the permissions anyway.
