I have Adobe CS5 installed and running on the Windows 7 side of my machine. Since I'd hate to boot up into Windows just to use Photoshop, I'm trying to get it in Ubuntu 12.04.

Tutorials I found suggested that the easiest way to have it in Ubuntu was to install Wine, and copy my Windows installation over.

Here are the exact steps I've done up to this point.

From Windows, exported the registry key for HKEY_LOCAL_MACHINE >> SOFTWARE >> Adobe to the desktop.

Changed to Ubuntu, downloaded Wine from Software Center

Terminal:
$ sudo apt-get install wine ttf-mscorefonts-installer
$ winecfg
$ wget http://www.kegel.com/wine/winetricks
$ sh winetricks msxml6 gdiplus gecko vcrun2005sp1 vcrun2008 msxml3 atmlib

Moved registry export to home folder.

Copied
"Program Files (x86)\Adobe" to "~/.wine/drive_c/Program Files (x86)/Adobe"

"Program Files (x86)\Common Files\Adobe" to "~/.wine/drive_c/Program Files (x86)/Common Files/Adobe"

"Documents and Settings\Don\Application Data\Adobe" to "~/.wine/drive_c/users/don/Application Data/Adobe"

"Windows\System32\odbcint.dll" to "~/.wine/drive_c/windows/system32/odbcint.dll" ,and lastly

"Windows\System32\odbc32.dll" to "~/.wine/drive_c/windows/system32/odbc32.dll".

From Terminal, $ wine regedit adobe.reg.

Right clicked on Photoshop.exe and selected "Open with Wine".

Got the message "Wine Program Crash, Internal errors - invalid parameters received."

So to restate my question, How can I get Photoshop running in Ubuntu 12.04? I'm not sold on doing it in this specific way, I just want to use Photoshop without having to reboot. What's the best way to make this happen?

Edit: I do not have the installation CD, no.
