--- Comment #3 from Jean-Sébastien Frerot jsfrerot@egliseespoir.com 2009-03-13 08:24:23 --- Ok, I tried to investigate more on this as my wine installation is still not working. I found that the only difference between my .wine folder create by a 32 bits ubuntu os and a 64 ubuntu os are these 3 files: system.reg, userdef.reg and user.reg. Replacing the files from the 32 bits installation into my 64 bits installation, I found that the drives are now shown in "Drives" tab. The file that fixed the problem is system.reg and the lines that were missing in this file are:
[System\CurrentControlSet\Services\MountMgr] 1216050542 "Description"="Device mounting service" "DisplayName"="Mount Manager" "ErrorControl"=dword:00000001 "ImagePath"="C:\windows\system32\drivers\mountmgr.sys" "ObjectName"="LocalSystem" "Start"=dword:00000002 "Type"=dword:00000001
I noticed that there is a lot more missing section in the system.reg generated by the 64 bits Ubuntu installation. So my guess is that there is a problem when generating these files on a 64 bits installation.
