dll and software

I have Windows 7 64, when I try to update Adobe reader or install Silverlight and some other programs I get error codes; 1603 1644 dll or what have you.

Can I use recovery discs on my Asus computer and repair the Windows install or will that just flat out start all from scratch?

 

I tried the Microsoft's uninstall tool but no go.

 

The Adobe reader is 9.4
I don't know what Silverlight there is because although it shows up on CCleaner's uninstall list, I can't find the program anywhere and can't run web pages that use it.
The tool I used last night was the Windows Uninstall Tool.

For Silverlight, I uninstall from CCLeaner, goes through the steps and confirms, then try to install latest .exe file from Silverlight but gives me a "Installation failed 1603" message and that's it. At that point, on CCLeaners uninstall section there is a Silverlight entry of 45kb but that's it.

For Adobe reader, if I try to install the new 10.1 version it will go throught the motion and then give me a 1604 error code.

 

You can use the Windows Installer Cleanup Utility (http://majorgeeks.com/download.php?det=4459) to uninstall the current version of Adobe Reader.

If you still have problems, please quote the exact message you are getting.

 

Windows Installer Cleanup Utility, that's the tool I meant that I used when I said Windows Uninstall tool...
Silverlight version is 0.000.000, so it seems to be gone. Still can't install anew, that gives me a Message ID 1603, install failed.
Adobe Reader installation gives me "Error 1402 could not open key" and a large string of characters. It says to verify I have access to key which as Admin, I should.

 

I'll try that.
If that doesn't work I think I will just go ahead and do the recovery process and reset the whole damned thing to factory.

 

Tried it but I can't even find the key in there. It is not in there, I'm fed up with trying I will do the recovery tomorrow.

 

No, the free downloads, the Acrobat Reader.
