SteelCentral AppInternals 10.x installer on Windows servers seem to be stuck at o_ScanForRunningInstrumentedProcesses

Categories: SteelCentral AppInternals (AppInternals Xpert)
Solution Number: S33178


We are running SteelCentral AppInternals 10.x installer on Windows and after launching the installer and couple of minutes the Next button is grayed out and does not allow us to continue with installation. When we check the Installer log we see that the install is stuck at o_ScanForRunningInstrumentedProcesses

MSI (c) (D8:A0) [11:23:19:121]: Doing action: o_ScanForRunningInstrumentedProcesses
Action 11:23:19: o_ScanForRunningInstrumentedProcesses.

When running the Windows Installer to install SteelCentral AppInternals 10.x there are couple of things which you can try
  • Right click on the installer exe and run it as 'Administrator'
  • If the above does not work you can launch command prompt as 'Administrator' and try running the installer
If the neither help, then you need to check the MSI installer log on the system which can be found in the following location on the Windows server

If the MSI log shows that the process is stuck at o_ScanForRunningInstrumentedProcesses


To workaround the issue you can run the installer with following flag from command prompt
>AppInternals_Agent__Win.exe /v"O_SI_SKIP_SCAN=TRUE"

!! DO NOT COPY AND PASTE, but please type the flag as shown above. There were cases where copy and paste did not help !!

The flag will help you skip the scan where the installer seem to be getting stuck. Skipping the scan when no applications are instrumented is fine.  If an application is instrumented, you may need to restart the system since that application will have a lock on some files we are trying to upgrade.  

Not sure if you will always see a "need to restart" dialog at the end of the install when a restart of the system is needed since we try to suppress that dialog.  If you use this option, it would be wise to restart the system after installation is finished.
