Can't install or uninstall .net framework 1.1

Posted on 2005-05-02
Medium Priority
Last Modified: 2012-06-27
System has a number of problems, after a bad cloning and upgrade to XP Pro SP2 .... Java applets a problem (different issue, same system and another Q in this TA on that) and .net framework 1.1....

Tried to do WindowsUpdate to add the most recent service pack for .net framework .... never completes, always fails.  Tried removing it using the add/remove process but also always fails, is there but tells me it's not installed .... ?

Check this information from Microsoft, but still leaves me in the same place.  

Installation Repair
You may need to repair your installation of the .NET Framework after upgrading your operating system or if the system becomes corrupted.

To repair the .NET Framework
Obtain the original installation source. For example, if you installed the .NET Framework from CD or DVD, insert the disk. Or, if you downloaded the .NET Framework, download again and choose to save to disk. If you installed from a network share, reconnect.
On the Start menu, choose Run.
For Windows 98 and Windows Me type:
For Windows NT, Windows 2000, Windows XP or later, type:
In the command window, type the following:
n:\<Installation Source>\dotnetfx.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\netfx.msi"

For example:
d:\dotNetFramework\dotnetfx.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\netfx.msi"
To repair a .NET Framework Language Pack
Obtain the original installation source. For example, if you installed the .NET Framework Language Pack from CD or DVD, insert the disk. Or, if you downloaded the .NET Framework Language Pack, download again and choose to save to disk. If you installed from a network share, reconnect.
On the Start menu, choose Run.
For Windows 98 and Windows Me type:
For Windows NT, Windows 2000, Windows XP or later, type:
In the command window, type the following:
n:\<Installation Source>\langpack.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\langpack.msi"

For example:
d:\dotNetFramework\langpack.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\langpack.msi"


Again, when I try the uninstall, it tells me that it can't be done, product not installed, yet resides in the add/remove process.

When I try to install the WindowsUpdate service pack, get errors and points here:
Security Update for Microsoft .NET Framework, Version 1.1 Service Pack 1 (KB886903)
A security issue has been identified that could allow an attacker to compromise your Windows-based system running the Microsoft .NET Framework and gain access to restricted data. You can help protect your computer by installing this update from Microsoft. After you install this item, you may have to restart your computer.
How to Uninstall
This software update can be removed via Add or Remove Programs in Control Panel.
Help and support

Installation error message from WindowsUpdate is:
The upgrade cannot be installed by the Windows Installer Service because the program to be upgraded may be missing or the upgrade patch may be a  different version of the program.  Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.

Don't really know if this will help, but have you tried the "aspirine" approach?

Renaming MSCOREE.DLL and retrying the install?

I've seen it solve so many errors when installing .NET framework, that I wonder...

Asta, I haven't seen your error message before, so see this as a wild shot.

Thank you both.  Ash, I've tried the 3.0 before, but as it says there:  "Windows Installer 3.0 Redistributable supports Windows 2000 with Service Pack 3 or later, Windows XP, Windows XP Service Pack 1 and Windows Server 2003. Windows XP Service Pack 2 contains Windows Installer 3.0 and therefore can't be installed or upgraded by this redistributable" ....

Zee, I'll try the renaming of that dll.

I found it further frustrating when doing research on this (months now); and found that with all these fiddlings, can't access the OfficeUpdate process without errors; and points to gdiplus.dll .... shows as missing and installer problems as well.

This has been a long process, and so far no luck; will try the renaming.

Sadly, no change.

This is what I get when I try OfficeUpdate.... and again, likely due to the installer issues and versions...

Office Update is unable to check for updates Help
The Office Update site is unable to check for updates on this computer. This may be happening because of one of the following reasons:

You do not have administrative privileges for this computer. (not true)
There is a network problem and the detection catalog used by the Office Update site failed to download. Go back to the Downloads home page and try running detection again. (no help)
Windows Installer patch files (.MSP files) from previously applied Office updates are missing from the \Windows\Installer hidden directory on your computer. MSP files are stored on your computer after update installation completes because they need to be referenced for future update operations. If the files are missing you will not be able to apply Office updates. You may also be unable to uninstall Office products as a result of the same problem. Please contact Microsoft Product Support Services for assistance. (already done)
You installed Office updates in the past and then upgraded from Windows Installer version 1.0 to Windows Installer version 1.1. For more information see the KB article Windows Installer May Prompt for Install Source if Unavailable. (exactly what was done when I upgraded to SP 2)

I should add that I had installed the WindowsInstaller version 3.1 update as noted here:

But problems still persist.

sfc /scannow also run.

Thanks a bunch to you both.  The detail from MS worked 100%!  Yay!  MSCOREE.DLL was a piece of the process.

Happy FRIDAY!  Or should I say "YAY-Day"

Next, the other issue of Java Applet problems, other question here.
