Hello Mohammed,
You need to download both the Solaris and Windows packages of SWPM and of course unpack each package on each o/s.
Solaris:
In the directory where you have unpacked SWPM, as user "root" execute:
# ./sapinst -nogui
If you have logged on as a user other than "root" and then performed a "sudo" then you need to run sapinst as follows:
# export SAPINST_REMOTE_ACCESS_USER=<the user you logged on to Solaris as>
# ./sapinst -nogui
Windows:
In the directory where you have unpacked SWPM, double click on the sapinstgui.exe file and supply the hostname or IP address of the server where you have started the SWPM on Solaris as well as the user you specified with SAPINST_REMOTE_ACCESS_USER.
KR,
