Everytime I try to install Photoshop CS3 or 4, my computer fails to accomplish the task. It always fails to install both the Photoshop program and Adobe AIR. It says, "Error 1603," when I try CS4 and simply says, failed to install for CS3. I've heard that it could have something to do with certain programs so I uninstalled everything that wasn't necessary. Then I removed extra space on the hardrive so I have plenty of room. I cleaned the registry and temporary folders with multiple programs and made SURE to remove all Adobe files other than Reader and the Media Player. I restarted the computer. I even used the task manager to shut down any unnecessary tasks before INSTALLING. It still won't work. Can anyone help?

6.0.6001 Service Pack 1 build 6001
HP Pavilion
System Model GX613AA-ABA a6300f
System Type x86-based pc
SMBIOS Version 2.5
