I purchased Adobe Acrobat 6.0 recently and have been having the same problem over and over again. Just as the installer is about to install the software package from the CD-Rom I get the following Message -
Error 1606: Cannot access network location
and then something about "XLStart"
My OS is XP SP2, P4 w/ 1GB ram. 64MB VRAM.
This is the only software package that exhibits this problem for me...
