You may need to copy the Adobe TWAIN driver, if your scanner requires it, from the optional plug-ins folder to the Import-Export folder in the main plug-ins folder.
You will need to copy the plug-in Twain_32.8ba
C:\Program Files (x86)\Adobe\Photoshop Elements 11\Optional Plug-Ins\Import-Export
C:\Program Files (x86)\Adobe\Photoshop Elements 11\Locales\en_US\Plug-Ins\Import-Export.
On Macintosh, copy the ImportModules folder to plug-ins.
//Applications/Adobe Photoshop Elements 11/Support Files/Optional Plug-Ins/
//Applications/Adobe Photoshop Elements 11/Support Files//Plug-Ins/
N.B. The app store version of Elements has a different file path.
for 99jon. Thanks for the informaation, but I don't find the folder "Import-Export" under \Locales\en_US\Plug-Ins on my hard drive. Should I create it? Also, when using PSE 9, it recognized that I have VueScan software as my primary scanner software and added that to the list under "import"
Simply move the Import_Export Folder from optional plug-ins to plug-ins
