Problem with extyernal program
 

Excuse me if my english fail. OK?

I writing one NSIS instalation for a program distributed into two CDs. To do this i using 7-Zip to decompress the files into the CDs. The problem is on executing 7-Zip inside the instaler.

At the moment that i call 7-Zip it show his window, i need to wait the decompressor finish and hide or disable the decompressor window to prevent the user to close the window and breake the instalation.

ExecShell can hide the decompressor window, but did'nt wait her finish. I using ExecWait to start the decompressor, but what i do to hide his window?

To hide 7z.exe console use nsExec or ExecDos plug-ins.
