problem happened when adding reg file using "regedit /s " which belongs to a subcommand. example: description.1=AAA command.1=BBB description.1.0=CCC command.1.0=regedit /s file.reg (file.reg is a must-be file for AAA's registration) when I chose to install AAA and CCC, WIHU shows that every thing is ok. Howerver file.reg is not imported to registry at all (I cheked in registry). =========== If I do like this description.1=AAA command.1=BBB description.2=CCC command.2=regedit /s file.reg when I chose to install AAA and CCC (or CCC only), command2 does work, file.reg was added. =========== I tried for many ways i.e description.1=AAA command.1=BBB description.1.0=CCC command.1.0=regedit /s file.reg description.2.0=DDD command.2.0=other command also the result is file.reg is not added =========== I am confused why reg file can only by added in the first level command and can't be used in sublevel command? I have to chang running AAA and CCC by using a single cmd file. *************** btw, another question, wihu can't be run at T12. Though the interface is come out you cann't go on. Because the current user is SYSTEM. That is you can't call it in cmdlines.txt. You have to run it in [Guirunonce]. If so you don't need to creat new user at all because you have done it mannualy before wihu is called. Looking forward to hearing from the author. thanks.
