Actually it is portable, You don't install it on your flash drive, (though I guess you could, its not going to hurt making it portable) Then you need to remake your registry key: Make a new text file name it whatever, but we are going to call it CS2 and place this in it: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{236BB7C4-4419-42FD-0409-1E257A25E34D}] "EPIC_ORG"=" PUT YOUR COMPANY HERE " "EPIC_SERIAL"=" YOUR SERIAL GOES HERE " "stockphotos_Relative_productfolder"="stock photography\\\\Adobe Stock Photos 1.0.msi" "stockphotos_product_code"="{786C5747-1033-0000-B58E-000000000001}" "stockphotos_product_name"="Adobe Stock Photos" "LanguageID"=dword:00000409 "commonfile_Relative_productfolder"="commonfilesinstaller\\\\Adobe Common File Installer.msi" "commonfile_product_code"="{8EDBA74D-0686-4C99-BFDD-F894678E5B39}" "HelpPath"="Adobe\\Adobe Photoshop CS2\\Photoshop_9.0_en-us.zip" "EPIC_NAME"=" PUT YOUR NAME HERE " "InstallerTitleBar"="Adobe Photoshop CS2 - Setup" "bridge_product_name"="Adobe Bridge" "helpcenter_product_name"="Adobe Help Center" "helpcenter_product_code"="{E9787678-1033-0000-8E67-000000000001}" "helpcenter_Relative_productfolder"="Help Center\\\\Adobe Help Center 1.0.msi" "commonfile_product_name"="Adobe Common Files" "TryOut"="en_US" "ProductSIFFile"="PS.sif" "epic_eula_accepted"=dword:00000001 "epic_eula_selected"=dword:00000000 "bridge_product_code"="{B74D4E10-1033-0000-0000-000000000001}" "bridge_Relative_productFolder"="bridge\\\\Adobe Bridge 1.0.msi" "ProductHelpIdentifier"="Photoshop" "ProductHelpVersion"="9.0" "SubProductList"="Adobe Bridge, Adobe Common Files, Adobe Help Center, Adobe Stock Photos" "AuthorizedCDFPrefix"="" "Comments"=" " "Contact"="Customer Support" "DisplayVersion"="9.0" "HelpLink"=hex(2):68,00,74,00,74,00,70,00,3a,00,2f,00,2f,00,77,00,77,00,77,00,\ 2e,00,61,00,64,00,6f,00,62,00,65,00,73,00,75,00,63,00,6b,00,73,00,2e,00,63,\ 00,6f,00,6d,00,2f,00,73,00,75,00,70,00,70,00,6f,00,72,00,74,00,2f,00,6d,00,\ 61,00,69,00,6e,00,2e,00,68,00,74,00,6d,00,6c,00,00,00 "HelpTelephone"="1-800-244-8487" "InstallDate"="20060115" "InstallLocation"="Adobe\\Adobe Photoshop CS2\\" "InstallSource"="No-InStall" "NoRemove"=dword:00000001 "Publisher"="Adobe Systems, Inc."

Now we will copy our photoshop from the programs folder and put it on your flash drive, we will now navigate to where our photoshop exe file is located on your flash drive and paste our two registry keys. Now open up notepad again and make a .bat file as follows: REGEDIT /S Adobe_Photoshop_CS2/CS2.reg start Adobe_Photoshop_CS2/Photoshop.exe ____________________________________ Now we will save it as Open.bat And make another: REGEDIT /S Adobe_Photoshop_CS2/unCS2.reg _____________________________________ Lets save it as Unregistry.bat Note that instead of the default "Adobe Photoshop CS2" I've named it "Adobe_Photoshop_CS2" because the .bat files won't work otherwise. And congrats, photoshop is portable, and as long as you keep it on only one copy, its still leagal. Note there will be a program error when you start the application, but it doesn't do any harm or subtract from the useablility of the program. Its just annoying, thats all. To open the program, Click the Open.bat file, and to clean out the registry click Unregistry.bat Hope this works for you and have a great day! (Note: I am not going to be held accountable for you doing this, if you mess something up, you are on your own and if it doesn't work for you, then I'm sorry, I've given you all the help I can.)
