Create a silent install of Mozilla ThunderBird ---------------------------------------------- 1) Have a copy of Mozilla Firefox 2) Run the THunderBird setup program, and, while it is still on the first screen, go to your %USERPROFILE%\7z*.* folder (EG: where the mozilla setup extracts its files to before installation), and copy all of the files in that directory to a temporary directory. I will use TB_TMP for this howto. 3) Do the same with firefox that you did with ThunderBird. I used FF_TMP for the temp folder for FireFox. 4) Make 2 more temp folders, FF_XPCOM and TB_XPCOM. 5) Extract the XPCOM.XPI file in the FF_TMP directory to the FF_XPCOM directory. Extract the XPCOM.XPI file in the TB_TMP directory to the TB_XPCOM directory. (These files can be extracted using any standard unzip program) 6) Copy the install.js file from the FF_XPCOM to the TB_XPCOM folder. 7) Copy NSPR*.dll, plc*.dll, and plds*.dll from the FF_XPCOM folder to the TB_XPCOM folder. 8) Zip the TB_XPCOM folder (Make sure your program recreates the internal directory structure) to TB_XPCOM.ZIP 9) Backup your original XPCOM.XPI located in the TB_TMP folder. 10) Copy TB_XPCOM.ZIP to the TB_TMP folder and rename it XPCOM.XPI 11) Backup the setup.exe file in the TB_TMP folder 12) Download a mozilla installation (full install). I used this one: mozilla-win32-1.7.1-installer.exe Get it at ftp://ftp.mozilla.org/mozilla.org/mozilla/releases (You can also use the setup.exe from your unattended FireFox installation if you've done one using the mozilla setup method, that's what I did. ) 13) Using the same techniques we used in steps 1 and 2, run the Mozilla installation and when the first screen comes up, go to your %USERPROFILE%\7z*.* folder and get the setup.exe... I believe it's called Mozilla-Install.exe or something of the sort. (Sorry, I've already deleted the original Moz. installer and don't want to download it again). Anyhow, copy the setup executable (it's about 245k) to your TB_TMP folder. 14) Rename the moz. install file (the one we just retrieved from the %UESRPROFILE%\7z*.* folder) to setup.exe 15) Make a backup of the config.ini file that is now in TB_TMP. 16) Open the config.ini in TB_TMP and change the line that says Run Mode=Normal to Run Mode=Silent (It's the 1st non-commented line in the file) and save it. 17) Run this command: <path to setup>\Setup.exe -ma -ira to have TB install silently. 18) For those of you that really want to save some space, extract each of the XPI files to it's own directory and then recompress them using your programs highest level of compression. I did it with IZArc and the total size of the install directory for TB dropped from 22mb to 12mb. And hey, when you're dealing with 700mb (of which XP Pro SP2 takes about 590), 10 megs can be a life saver. The problem everyone keeps referring to where, when using the -ma -ira switch with a clean TB install, a freeze occurs at the install directory page because of some error/change in the xpcom component. This is a work-around for that error. Though three of the files are older, I'm assuming (since they were from netscape) that they have no major impact on TB's workings. And, so far, I have had no problems running it for 3 weeks. So, if anyone has a problem with TB after it's installed this way, let me know about! Have fun, and hope this helped --RJ
