Run Command syntax

[j-gray 31]

This should be simple, but I'm having no luck. Task runs successfully but nothing happens on the clients.

At the command line, this works perfectly:  "C:\Program Files\CCleaner\uninst.exe"/S

I have the task set as follows:

Command line to run:  uninst.exe /S

Working directory:  C:\Program Files\CCleaner

I also tried the following:

Command line to run: "C:\Program Files\CCleaner\uninst.exe"/S

Either version runs successfully but does nothing.

Does the 'working directory' require quotes due to space in the path? I don't believe anything is being logged...

Using the first option (command line to run and working directory both populated), I see the following in a batch file that is left in C:\Windows\Temp:

uninst.exe /S
del C:\Windows\TEMP\ra-run-command-92b883c9-c357-4610-9ecb-62cfa0e9f907.bat

The second line is obviously failing as the batch file is still in the directory. I'm assuming based on the command that it's not referencing the working directory?

If I recall correctly, working directory is probably set by "parent" process, i.e. it is set before script is started, and therefore it is not visible in script content directly.

Regarding removal of script, in case path is correct, could you verify that script is not running? In case it is blocked on execution of first line, it might explain why delete operation was not called...

Also note, that most common issue with run command taks is that scripts are executed with AGENT's security context, i.e. as LOCAL SYSTEM, which might have limited access to specific resources, including user desktop, and therefore extra care has to be made when accessing network shared, protected disks or even executing applications that might require access to desktop environment, or environment of standard user.

Regarding working directory, I put quotes around it and it failed. This is counterintuitive, as at a command prompt, it will fail without quotes due to the space in the path.

I'm going to guess that it's a permissions issue. On my test system, the task runs successfully and uninstall is successful using the command below:

Command line to run: "C:\Program Files\CCleaner\uninst.exe"/S

On any other system (all are Win10), while the task runs successfully, the uninstall does not start and the ra-run-command batch file remains in C:\Windows\Temp.

Any suggestions on how to get this simple task to run?

Does it actually do something if you run the command via "psexec -s" in the system account?

Yes, this method works.

I also tried the task by going to client details, then 'Installed Applications'. I selected CCleaner from the list of applications, then clicked the 'Uninstall' button.

That gave the following error:  "SoftwareUninstallation: No applications matching name 'CCleaner' were found"

Despite the application being installed and being selectable as an application, it does not run.

I also tried the software uninstall client task, but CCleaner does not appear in the list of applications to select.

Pretty frustrating...
