Windows installer will not work under Safe Mode, this means that programs cannot be installed or uninstalled in safe mode without giving a specific command usin g msiexec in command prompt. you will have to fo this seperately on every user's login as needed. To make windows installer to work under safe mode you need to create a registry entry for every type of safe mode you are login into:
>>>>>>>>>>>>>>>>>>>>>>. Safe Mode: ----------Type this in a command prompt: REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer"/VE /T REG_SZ /F /D "Service" Then start the Windows Installer service by typing "net start msiserver"
>>>>>>>>>>>>>>>>>>>>>. Safe Mode with Network: -----------------------Type this in a command prompt: REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer"/VE /T REG_SZ /F /D "Service"
Then start the Windows Installer service by typing "net start msiserver" >>>>>>>>>>>>>>>>>>>>>>>>>>
eg- create a ".bat" file with the above command and run it as below for ease. ===========startMSI.bat================= REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer"/VE /T REG_SZ /F /D "Service" Pause =========================================
