According to above log, it is not like nothing happens but SMS actually runs the program and program exits with exit code 1.

SMS considers exit code 1 as a failure code. Typically, 0 is considered as success.

Asked customer double confirmed using below command remotely on test client without /silent switch in command line.

\\SMSserver\SMSPKGD$\T0100000\setup\sapupdate.bat

We got below error msg:
clip_image001

2. In process monitor log, we found when setup process down, the program will write some msg to C:\WINDOWS\SapSetup.log

=======================
899  下午 02:36:58.7529949  SapSetup.exe 3196      SetRenameInformationFile   C:\WINDOWS\SapSetup.log      NAME COLLISION   ReplaceIfExists: False, FileName: C:\WINDOWS\SapSetup1.log
=======================

3. We collect SapSetup.log for further check
===============================

14:35:31  SapFeiUt  3   Security : failed to calculate CRC32 checksum for 'C:\WINDOWS\system32\CCM\Cache\setup\sapsetup.xsc'

===============================

According to above log, we can find the setup program made a mistake with wrong path to C:\WINDOWS\system32\CCM\Cache\setup\ from C:\WINDOWS\system32\CCM\Cache\T0100000.1.System\setup\

So that’s why setup always failed with “Failed to open/parse setup script C:\WINDOWS\system32\CCM\Cache\setup\sapsetup.xsc”

It seems SAP setup program doesn’t support the directory structure like …\T0100000.1.System\setup\

Due to the install file is designed by GPO deployment. We can workaround it by using bat file and add a copy statement to avoid above App installation path redirect error.
