Hi, have overcome installation problems and now I cannot find C:\Program Files\Adobe\Photoshop Elements2\Previews\Cache to manually delete it. Any suggestions, please?

What OS?

In XP, open "My Computer", Select (top menu) Tools->Folder Options->View
and move dot to 'show hidden files and folders" and then remove tick from Hide Operating System Files. If under 2000, think it is the same, under Win 98 think you just have to place the dot in 'show all files'. If it is there, then it should be visible.

Thanks, Cass, I will give that a go in XP.
