Installation Server: The specified path is not valid Installation Server!

hello all,

i have installed a installationserver from the 7.10 presentation cd. that worked out fine. now i want to import different GUI versions, like 6.20 and 6.40 for mass-installation.

i click on "import products" and specify the location where my installationfiles lay. (i downloaded and exctracted presentation cd1 for 6.20 and 6.40)

no matter what directory i specify, it always sais: "<b>The specified path is not valid Installation Server</b>!" (note the wrong english in the message) 😉

i dont get it... ?-[

thx 4 your help
