GUI 740 SP5 - registry entries ConfigFileOnServer disappearing

Hello

We just migrated SAPGui installation server to 7.40 Compilation 2 with GUI 7.4 SP5

In package installation settings we are using option to use central configuration file:

NwEngine.Shell.SetRegValue "HKEY_LOCAL_MACHINE\SOFTWARE\SAP\SAPLogon\Options\ConfigFileOnServer", "REG_EXPAND_SZ", "\\server\SapLogonTree.xml"

NwEngine.Shell.SetRegValue "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SAP\SAPLogon\Options\ConfigFileOnServer", "REG_EXPAND_SZ", "\\server\SapLogonTree.xml"

but those registry entries are existing only for day or two and next morning disappearing from users workstations.

I've already checked following notes:

2075150 - SAP Logon (Pad) 740: New format of configuration files as of SAP GUI for Windows 7.40

2220930 - How to enable SAP UI Landscape format for SAP GUI for Windows 7.40

2175912 - SAP Logon (Pad) 740: favorites to the server connection entries are missing after migration

2225093 - SAP Logon (Pad) 740: command parameters /INI_FILE=... and /LSXML_FILE=... didn't work anymore in PL4+PL5

but nothing matched ....

We are also using:

NwEngine.Shell.SetRegValue "HKEY_LOCAL_MACHINE\SOFTWARE\SAP\SAPLogon\Options\SapguiNTCmdOpts","REG_SZ","/SUPPORTBIT_OFF=MAX_WSIZE"

NwEngine.Shell.SetRegValue "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SAP\SAPLogon\Options\SapguiNTCmdOpts","REG_SZ","/SUPPORTBIT_OFF=MAX_WSIZE"

and those registry entries are always in place ....

Any hint how to trace this issue or resolve it ?
