Here's a neat tip John Behneman sent me the other day. If you have any plans on sequencing Photoshop then this one's for you:
When sequencing Adobe Photoshop Elements 4.0 you may be presented with the following error during the installation process:
Adobe Photoshop Elements 4.0 - Setup
Error 1406.Could not write value RegOwner key \Products\B1F5E89CB2C51DF4DB9F3F77D9ACAA61\InstallProperties. Verify that you have sufficient access to that key, or contact your support personnel
'Abort', 'Retry', or 'Ignore'
If you run into this then the following steps should offer a workaround for this issue:
 Install Adobe Photoshop Elements 4.0 locally on your sequencing workstation.
 Export the key "HKLM\Software\Classes\Installer\Products\B1F5E89CB2C51DF4DB9F3F77D9ACAA61", save it to a central location for later use.
 Discard Changes/re-image your Sequencer, then follow the below instructions:
1) Begin your new sequencing; when you reach the Install Phase and are in monitoring, import the Reg Key from the steps above, confirm it has been created.
2) Run the install of Adobe Photoshop as normal, installing to Q:\%ROOT.DIR% (assuming Q is your Sequencer drive letter).
3) When the install is completed, you should be prompted to Reboot; click Yes to reboot, this should be intercepted by the Sequencer, then Stop Monitoring.
NOTE: I observed odd behavior that occurs when you import the registry key prior to installing Photoshop; for some odd reason, many of the files, including the Program Executable, are not created during the install, which is the reason for the following step
4) Begin Monitoring again to simulate the reboot, then run the install for Photoshop again. Select the REPAIR option during the second install, which should create all missing Program Files for the application to work properly.
5) When the install is completed, go to the install location of Photoshop and run the program executable to launch it. Choose Start from Scratch. Close it once it has successfully launched.
6) Complete the install wizard, and go into the Shortcut Wizard. Modify the OSD file name, etc., as preferred, then launch the application. Select Start From Scratch, once it has successfully launched, close the application. You will have to then click on Stop/Terminate to kill the application fully, as it spawns a process which remains in the system tray (this will add the Terminate Children tag into the OSD, which you will want to disable during streaming).
7) When the application has been fully shutdown during the Shortcut Wizard, complete the sequence and save it.
8) Modify the OSD file, setting "TERMINATE CHILDREN" to False. This was added when terminating the app in step 6, due to a child process being spawned. This does not occur on the client. What happens if set to True is that once the loader screen disappears for Photoshop, all child processes, including the application you open will be terminated).
9) Publish your sequence on the Virtual Application Server.
Thanks John! I also came across this recipe for Photoshop Elements that looks to be very well done so you might want to give that a quick once over as well. Keep in mind that I have not personally tested this process or the referenced recipe so neither I nor Microsoft can make any guarantees as to it's suitability or performance in your environment.
