New HD - Installed Winxp Sp3, no previous reader or acrobat installation. Photoshop V6 and imager reader V3 installed.
After successful (8 downloads of both V9 & V11 all deleted but one each of V9 & V11)
There are no warning messages, after clicking install nothing happens.
Oh, by the way... I've used both acrobat and reader for years with no problems!
