in thread Need to Execute msiexec using Net::Telnet

I am beginning to think that your Telnet session does not have enough priviledges to run msiexec, and that msiexec is objecting via a pop up which is ruining your telnet session. MS might have come to the conclusion that it would be bad for remote users to install software.

If you wish to continue to the bitter end:

So now we know that you can execute simple commands via telnet. The next command to execute is perl -v

Then a perl script that executes the msiexec command for you. This script should be first tested on the target machine (i.e. not via telnet). Then via telnet.

Once this has been done we know that msiexec can be started remotely and there is not some Windows weirdness that prevents it from happening, we can concentrate on the final step of eliminating the need for the perl wrapper on the target machine - which I agree is an excessive requirement in general but useful as a stepping stone to finding asolution.

By taking these small steps we are eventually going to run into the actual problem that is occurring here, its tedious, but as Edison said: 1% inspiration, 99% perspiration.

    Hi Philip,

    Thanks for your help. As per your suggestion, I copied a Perl script on remote machine that executes the command line i was trying. Then I initiated this perl script on remote machine using local perl script that uses Net::telnet module. Please see below output I saw on the command line-

    C:\Compatibility_Automation_Temp>perl command is: [perl C:\Compatibility_Automation_Temp\ - +i sep] output is: T h i s i n s t a l l a t i o n p a c k a g e c o u l d n o t + b e o p e n e d . V e r i f y t h a t t h e p a c k a g + e e x i s t s a n d t h a t y o u c a n a c c e s s i t , o r +c o n t a c t t h e a p p l i c a t i o n v e n d o r t o v + e r i f y t h a t t h i s i s a v a l i d W i n d o w s I n s t a +l l e r p a c k a g e . C:\Users\Administrator
    This simply says that we can't execute msiexec using remote mahcine :( (the same you predicted earlier). So is there any workaround for this like get the privilege to access this msiexec utility from remote machine.

    I fear that from here we are departing into that unknown country from whose bourne no traveler returns: namely Windows system administration. No doubt somewhere there is a method for granting Telnet the appropariate system priviledges. However, I suspect Microsoft will have their own ideas about how to do remote administration, and it may be better to abandon this approach for the moment and see what the standard MS way of doing this is. Once this is knowm, I am sure Perl will come back into play to drive their approved system programatically, but clearly, before advancing further we need to know how to do it manually.

      Hi Philip, there is a proper documentation available on Microsoft's site. please check it-

      The examples mentioned here are in powershell and I don't wanna use powershell. Please look at it and see if there is any way in Perl to handle the scenario.

        Just translate the Powershell commands to Perl.
