Dear Experts,
I am trying to install and exe file using the system command. The function fails, resulting in a -1 status and no cmd output message.
The command is:
[status,cmdm] = system('D:\dbLNI_Finder.exe')
The file exists:
If I try to perform the same command for the same file but in a specific location (a pen drive) it works:
system('H:\for win\dbLNI_Finder.exe')
I tried to copy and replace the file several times, but no.
Any idea? Thanks!

@Brunno: Your problem is solved now. Then it does not matter, that I still do not understand the explanations.
Does
system('C:\Users\BMC\DBlni_Find\dbLNI_Finder.exe')
work or not?
As far as I understand, you do not want to install this executable, but run it.

@Jan: the command
system('C:\Users\BMC\DBlni_Find\dbLNI_Finder.exe')
work only if I open Matlab as admin.
Yes, 'run'. Install the software by running the executable.

Although I am the PC admin, the command worked only when I open the Matlab in Admin mode (right-click >> open as adm). Since this code is for a deployed application, my deployed application is also able to install the *.exe only if opened as admin.
Now, why I the 'system' function worked installing the *.exe from the PenDrive (an only from the pen drive) without mode restrictions for me, is a mystery (in terms of security, somewhat contradictory).
At the end, I understood that the system() function and the CMD have distinct permission executing the same command. Good to know.
Tks.

Check the settings of your virus protection. Does it allow to start executables from the concerned folder?

My antivirus program does not allow all applications to start executables from arbitrary folders. This is thought to stop crypto-trojans.
You did not tell us, if you have opened the Windows Command Shell with admin privileges or not.

This is the tricky part: NO, the Command Shell was opened without admin privileges and was able to install. The Matlab without admin privileges, not.
Just to be crystal clear, the Windows user I am using is the admin, maybe this is enough to Windows Command Shell, but was not to Matlab (since I still needed to right-click on Matlab icon and "runs as administrator")
Ok? Thanks!
