install the software , one after another?

[caomeisanhao]

Hi,guys
I want to install two software, software A ist the condition to install software B, both of them are big stuff.
I do :
Run Program>A.exe
Run Program>B.exe
I look the taskmanager, both of them are installing,so the install failed.
because B cannot be successfully installed,until A is finished to be installed.
so I do:
Run Program>A.exe
waitready>0
Run Program>B.exe
but seems the same.

how to do it, if I want to install A first,when A 100% finished, then begin to install B .Thanks in advance!

Do you have RP_Wait set to 1 ? If not I think that will be the problem.

To quote the help:

By setting RP_WAIT to 1 the script will wait until the program launched by Run Program has terminated before continuing. The default value of RP_WAIT is 0.

Give This A Try.
Let>RP_Wait=1
Run Program>A.exe
Run Program>B.exe
Let>RP_Wait=0
