Please note that although we don't explicitly support the use of SCCM with our InstallShield based ENVI installer, I've heard of at least one case where a user was doing this successfully. However, I've not heard of problems where the ENVI installer was returning an exit status of -3. Out of curiosity, if you have access to a /f2 debug log file produced from an unattended ENVI installation with exit status -3, is there any additional error details from this log? Since you are installing over your network, I wonder if some sort of periodic glitch/delay in network communications, server problems or timing issue could be causing the inconsistent failures. I'm told that for reliability, it's usually better to install from files that are copied to the local machine rather than trying to install over a network, because of these possible types of issues. Consistent with the idea of a separate problem, I noticed that in one of the results file that had been provided, the ENVI installation to the machine failed with exit code -3, where the following file copy error had also occurred: 19:03:01.61 C:\Windows>copy /y "\\machine1\SMSPKGD$\COE00759\Files\license.dat" "C:\Program Files\Exelis\license\license.dat" The system cannot find the path specified. 0 file(s) copied. However, a subsequent successful ENVI installation to the same machine then also showed a successful copy of that same file: 8:49:44.30 C:\Windows>copy /y "\\machine2\SMSPKGD$\COE00759\Files\license.dat" "C:\Program Files\Exelis\license\license.dat" 1 file(s) copied. I hope this can be helpful. Regards, Jim

I have added the verbose logging to our install script and it generated a 16mb log file.It appears that the MSI file is generating a 1603 error. Below is the last couple oflines when the installer appears to bail out.MSI (s) (A4:E8) [11:54:48:037]: Executing op: FileCopy(SourceName=EX9EB4~1.HTM|ExampleRestoreSavedROIs.htm,SourceCabKey=_E45E5AEB86BE1C3C84883BACCA049D34,DestName=ExampleRestoreSavedROIs.htm,Attributes=16384,FileSize=4584,PerTick=65536,,VerifyMedia=1,,,,,CheckCRC=0,,,InstallMode=58982400,HashOptions=0,HashPart1=-2100368678,HashPart2=-1617498022,HashPart3=1100167317,HashPart4=-35430890,,)MSI (s) (A4:E8) [11:54:48:037]: File: c:\Program Files\Exelis\ENVI53\classic\help\Subsystems\Programmers\Content\Additional Topics in ENVI Programming\ExampleRestoreSavedROIs.htm; To be installed; Won't patch; No existing fileMSI (s) (A4:E8) [11:54:48:037]: Source for file '_E45E5AEB86BE1C3C84883BACCA049D34' is compressedMSI (s) (A4:E8) [11:54:48:131]: Internal Exception during install operation: 0xc0000005 at 0x000007FEF7A7C7C1.MSI (s) (A4:E8) [11:54:48:131]: WER report disabled for silent install.MSI (s) (A4:E8) [11:54:48:131]: WER report disabled for non-console install.MSI (s) (A4:E8) [11:54:48:131]: Internal MSI error.
