--- Comment #4 from Darragh Bailey felix@compsoc.nuigalway.ie 2007-11-23 15:10:05 --- Looking at the output for traces for xlviewer (the application that the installer broke due to the original change)
Command line passed into msiexec
trace:msiexec:main bug 9628: argv[0] = "c:\windows\system32\msiexec.exe" trace:msiexec:main bug 9628: argv[1] = "/I" trace:msiexec:main bug 9628: argv[2] = "C:\windows\temp\IXP001.TMP\XLVIEW.MSI" trace:msiexec:main bug 9628: argv[3] = "CDCACHE=2" trace:msiexec:main bug 9628: argv[4] = "LAUNCHEDFROMSETUP=1" trace:msiexec:main bug 9628: argv[5] = "SETUPEXEPATH=C:\windows\temp\IXP001.TMP" SETUPEXENAME=SETUP.EXE /lpiwaeo C:\windows\temp\Microsoft" trace:msiexec:main bug 9628: argv[6] = "Office" trace:msiexec:main bug 9628: argv[7] = "Excel" trace:msiexec:main bug 9628: argv[8] = "Viewer" trace:msiexec:main bug 9628: argv[9] = "2003" trace:msiexec:main bug 9628: argv[10] = "Setup(0004)_Task(0001).txt CDCACHE=0 DWSETUPLOGFILE=C:\windows\temp\Microsoft" trace:msiexec:main bug 9628: argv[11] = "Office" trace:msiexec:main bug 9628: argv[12] = "Excel" trace:msiexec:main bug 9628: argv[13] = "Viewer" trace:msiexec:main bug 9628: argv[14] = "2003" trace:msiexec:main bug 9628: argv[15] = "Setup(0004).txt DWMSILOGFILE=C:\windows\temp\Microsoft" trace:msiexec:main bug 9628: argv[16] = "Office" trace:msiexec:main bug 9628: argv[17] = "Excel" trace:msiexec:main bug 9628: argv[18] = "Viewer" trace:msiexec:main bug 9628: argv[19] = "2003" trace:msiexec:main bug 9628: argv[20] = "Setup(0004)_Task(0001).txt"
which gets converted to the following in the case of process_args trace:msiexec:main argvW[1] = L"/I" trace:msiexec:main argvW[2] = L"C:\windows\temp\IXP001.TMP\XLVIEW.MSI" trace:msiexec:main argvW[3] = L"CDCACHE=2" trace:msiexec:main argvW[4] = L"LAUNCHEDFROMSETUP=1" trace:msiexec:main argvW[5] = L"SETUPEXEPATH=C:\windows\temp\IXP001.TMP\" trace:msiexec:main argvW[6] = L"SETUPEXENAME=SETUP.EXE" trace:msiexec:main argvW[7] = L"/lpiwaeo" trace:msiexec:main argvW[8] = L"C:\windows\temp\Microsoft Office Excel Viewer 2003 Setup(0003)_Task(0001).txt" trace:msiexec:main argvW[9] = L"CDCACHE=0" trace:msiexec:main argvW[10] = L"DWSETUPLOGFILE=C:\windows\temp\Microsoft Office Excel Viewer 2003 Setup(0003).txt" trace:msiexec:main argvW[11] = L"DWMSILOGFILE=C:\windows\temp\Microsoft Office Excel Viewer 2003 Setup(0003)_Task(0001).txt"
and to the following when using CommandLineToArgvW
trace:msiexec:main argvW[1] = L"/I" trace:msiexec:main argvW[2] = L"C:\windows\temp\IXP001.TMP\XLVIEW.MSI" trace:msiexec:main argvW[3] = L"CDCACHE=2" trace:msiexec:main argvW[4] = L"LAUNCHEDFROMSETUP=1" trace:msiexec:main argvW[5] = L"SETUPEXEPATH=C:\windows\temp\IXP001.TMP" SETUPEXENAME=SETUP.EXE /lpiwaeo C:\windows\temp\Microsoft" trace:msiexec:main argvW[6] = L"Office" trace:msiexec:main argvW[7] = L"Excel" trace:msiexec:main argvW[8] = L"Viewer" trace:msiexec:main argvW[9] = L"2003" trace:msiexec:main argvW[10] = L"Setup(0005)_Task(0001).txt CDCACHE=0 DWSETUPLOGFILE=C:\windows\temp\Microsoft" trace:msiexec:main argvW[11] = L"Office" trace:msiexec:main argvW[12] = L"Excel" trace:msiexec:main argvW[13] = L"Viewer" trace:msiexec:main argvW[14] = L"2003" trace:msiexec:main argvW[15] = L"Setup(0005).txt DWMSILOGFILE=C:\windows\temp\Microsoft" trace:msiexec:main argvW[16] = L"Office" trace:msiexec:main argvW[17] = L"Excel" trace:msiexec:main argvW[18] = L"Viewer" trace:msiexec:main argvW[19] = L"2003" trace:msiexec:main argvW[20] = L"Setup(0005)_Task(0001).txt"
Looks to me that the command line being send to msiexec is incorrect in the first place, and its only due to some unusual behaviour by process_args that the correct command line is extracted.
