Scripting

I have a script to uninstall a previous version of SPSS Statistics and install the new version which has been deployed to about 150 machines.  So far, ~60 were successful and ~30 have failed.  They are all running Windows 10 x64 v2004.  For the failures, the logs are the same:

021-09-23 09:31:14: Sending dependency IBM SPSS Statistics 28.0.0.msi to client.... 2021-09-23 09:39:58: Error received while sending dependency IBM SPSS Statistics 28.0.0.msi to client 2021-09-23 09:39:58: Deleting SPSS28.bat.... 2021-09-23 09:40:25: The last step timed out after no response from the client. Please try again. 2021-09-23 09:40:25: Error -1 received while deleting file SPSS28.bat

Just for grins I ran the script on 5 of the failures individually and 2 out of 5 worked.  I should mention the script is set to run automatically if offline and all machines were powered on and network connected at time of push.  This time, the logs are slightly different:

2021-09-23 11:42:07: Alert not enabled, moving to next phase.... 2021-09-23 11:42:11: Sending script SPSS28.bat to client.... 2021-09-23 11:42:14: Script sent 2021-09-23 11:42:14: Sending dependency IBM SPSS Statistics 28.0.0.msi to client.... 2021-09-23 11:42:21: Error 206 received while sending dependency IBM SPSS Statistics 28.0.0.msi to client

I've tried looking up what error 206 means and how to fix but I've found nothing.  I really don't want to have to touch up to 80-something machines to get this stupid program to install so any help would be amazing.

Thanks!
