I have been trying to install the net 3.5 or 4.5 framework in my Vista home premium 64 bit for about 2 weeks. I am trying to install a tax program and it requires it. I have been emailing a microsoft tech and it takes a week to respond back to me. I have tried all 3 of his suggestions without success. The setup just stopps and give a generic 1603 error. Does anyone know where the best support option is for me?

Try these :

The following solutions have resolved this error in the majority of cases:

-Make sure short file name creation is enabled on the target machine. You can check to ensure that the target machine does not have short file name creation disabled by navigating to the following registry entry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\FileSystem

Make sure the value "NtfsDisable8dot3NameCreation" is equal to 0. This indicates that short file name creation is enabled. A value of 1 indicates that this functionality is disabled. You should change the value to 0.

After modifying this value, the target machine should be rebooted before attempting to launch the setup again.

Note: If the target machine should normally have short file name creation disabled, it can be disabled after the install completes by resetting "NtfsDisable8dot3NameCreation" to 1 and rebooting.
-To ensure that the Windows Installer Service is properly installed and configured, it is recommended that users install the file InstmsiA.exe on Windows 95/98/Me or InstmsiW.exe on Win NT systems. These files are shipped with your InstallShield product and are located in the following location:
<Product Path>\Redist\Language Independent\i386

-Empty all temporary folders. The specific temporary folders for a machine can be determined by accessing the DOS prompt and typing set. Note the values listed for TEMP and TMP, and delete all files in those locations.
-Make sure no other applications, including utilities such as virus scanners, are running in the background. Close all running applications and utilities, and launch the installation again.
-If this error occurs during un-installation, use the Microsoft Windows Installer CleanUp utility to uninstall the installation.
-Once the installation has been successfully un-installed, you can then debug the project to determine what caused the original error.

Also if you have Google Desktop , remove it then try to install. Some people reported also that turning off anti-virus or antimalware softwares solved the problem.

If you have Spybot Search and Destroy installed and the Tea-Timer activated...switch off the tea-timer and try again.
