Hello,
Is there a way to run a batch file without showing the command prompt window AND where the command doesn't wait for the batch file to complete execution (ie, NO WAIT mode)?
I have been using nsExec::Exec and nsExec::ExecToLog to run batch files and exe, but I believe in all nsExec commands, it waits for the exe/batch to complete and return.
In this particular case, I wish to execute the batch in silent mode and wish to continue with installation without waiting for it to return. Can I use nsExec in someway in this case?
Any help in this will be appreciated! Thanks!!

nsExec in No wait mode?

You can use the ExecDos plugin for this.
Have been trying the ExecDos plugin, but never quite get it right I guess.
This is how I am calling it:
ExecDos::exec /NOUNLOAD /ASYNC '"$INSTDIR\my.bat" "$INSTDIR\abc.txt"'
where $INSTDIR\my.bat is the batch file and $INSTDIR\abc.txt is an input.
The problem I face right now is the batch file starts executing and stops mid way. Is there a time out? I read that the default time out is huge.
So I wonder what is causing the batch to start and stop abruptly.

!include LogicLib.nsh

sectionend Hi Anders,
I get an Error displayed.
What does that mean? I had tried setting the COMSPEC and executing with /c for Exec and it had stopped mid way too.

Return value is 0.
MSDN says 0 : The system is out of memory or resources.
I am confused 🙁

There is a off by one error there, it should be > 31 or >= 32.
If you don't care about the error code you can just do

Thanks a lot, Anders!
