execwait uninstall.exe is ok but silent mode not
 

hello

in my script i desinstall old version before install newer.

when i use:
ExecWait '"$R7\uninstall.exe" _?=$R7'
there's no problem, the install wait the desintall is finish to continue installation.

but when i use:
ExecWait '"$R7\uninstall.exe" _?=$R7 /S'
the install doesn't wait and continue.

so is ther any way to silently do this uninstall ?

thanks

The /S switch must be inserted before _?=. Everything after _?= is considered as $INSTDIR.
