Using OCS Inventory Packager is the fastest way to deploy and setup the OCS Inventory NG Agent on stand alone or domain integrated computers. It is based on the NSIS script and RemCom tools. It generates a file called ocspackage.exe based on your parameters, which allows a one click and/or a silent user install.

In this document a number of assumptions are made:

  • We assume that you know the domain or local administrative account of your computers.
  • You should also know how to generate or obtain a certificate file.
  • You are familiar with common Windows administrative tasks.


Download the Packager and the latest [OCS-NG-Windows-Agent-Setup.exe] program from the OCS Inventory Web Site.

Prepare your certificate (needed for software remote deployment).

Launch OcsPackager.exe and accept the License agreement.

The following window will appear:

“Files and Options” group box:

  • On the Exe File line, select your freshly downloaded OcsAgentSetup.exe program. This entry is required !
  • On the Certificate file line, select your cacert.pem file.
  • The other files line allows additional files to be specified which will be copied to your install folder.
  • On Command line options line you should enter all the needed options for the Ocs Agent setup program (e.g. /server=http[s]://my_server/ocsinventory:8181 /S). Do not forget to specify the /S option for a silent installation.
  • The Label line will create a label file containing your user prompt. The first time OcsInventory.exe starts, a popup using this prompt will be shown. The user entered value is called the TAG.

“Install will run under account” group box:

  • On User line, enter the local admin account or a domain administrative account. On Active Directory domains, use “@” to separate the user from the domain name (e.g. On a NT4 domain use the “domain\user” syntax.
  • Be careful when entering the password. It will not be validated at this point !

You should have something like this:

Click the [ Next ] button.

Select the destination folder and Click [ OK ].

At this point windows will briefly appear to generate ocspackage.exe.

You can now test ocspackage.exe by launching it under a normal user account (no administrative privileges).

A brief Ocs Inventory popup may show indicating the ocspackage.exe has been created. A log file named ocspackage.log is created at install time.

Publishing “ocspackage.exe”

You must now upload ocspackage.exe to the ocs web console or publish it on an alternative shared file system.

Publishing on the ocs web server

Log on to the administration console and select the Configuration icon:

Then upload your ocspackage.exe file.

Deploying agent on a domain

Refer to our documention to setup Windows Agent 2.X

Warning: Mysql server must accept files larger than 5M. Edit my.cnf file and modify max_allowed_packets value to fix it more than 5M. Save this file and restart service.
