Error Code: 0x80070645
I tried updating to the new Family Pack 3.5 Framework. This was the what I
received Error Code: 0x80070645 .
Anyone out there know how to fix this?
Thanks for your help.
I am getting this same error code when installing this update. My machine
does have .NET Framework 3.5 SP1 (BETA) installed previously. Working on
figuring out the root of the problem, and I will update here if I do...
I researched this and came up with this link:
I followed the intructions and I fixed the problem for me.
Hello, I got the same error. No beta installed. Windows Update says that the
product is already downloaded and can be installed. But the install reports
the error, mentioned in the subject, on the Windows Update Page only (no
error code is reported by the local install. The local install only reports
that the install was not successful - no reason mentioned).
How to fix it?
How to change the state: downloaded and ready to install?
How to remove the package from my local PC? or
How to make it work?
BTW - I have searched MS websites the whole morning to find a solution.
I have the same message and am totally lost. Help is appreciated.
RE: Error Code: 0x80070645
I glance at the article that OpusXX mentioned, and it looked similar to the
solution that I figured out.
In "add remove programs" from the control panel, be sure to check the box
that says "display updates". I had a beta version of .NET FW 3.5 installed
previously. I removed that update, rebooted my computer, then installed the
..NET FW 3.5 (most recent and NON BETA) and it all worked.
RE: Error Code: 0x80070645 help, someone, please?
Hi: I received the same error code, and have tried everything shown. I did
not have 3.5 beta installed, so, as per link someone here posted from
microsoft, I uninstalled all net framework programs on my computer, cosed
out, and then tried to run the indows install cleanup that the link saqid to
download next - but no reference there to any net framework showing to clean
up. So I turned off my machine eyt again, and tried to reinstall all net
framework programs that I'd had on my computer and uninstalled, and found
that I couldn't install even one of those programs. So it now appears I have
no net frameworks on my computer, I can't install or celan up anything, and
am just thorouly lost and confused. I will try to do the last-resort
uninstall (if there's anything left to uninstall) referred to in the windows
article, but I have a feeling I'm in trouble. Any suggestions from anyone?
I'd greatly appreciate. Thanks for your time.
For those people still having this issue I would like to know what OS you are
running. I have 2 people with this same error and both have XP Home SP3. I
have tried the resolution in KB923100 and still getting errors with update
kb951847. I will post back once I find a solution.
To anyone still having this problem, please post with your OS details. I
have seen this on 2 pc's and the actions from KB923100 did not resolve the
problem. Both of these PC's are running XP Home SP3.
RE: Error Code: 0x80070645
I followed "http://support.microsoft.com/kb/923100" which was mentioned in
- uninstalled all net framework versions
- run net framework clean up utility
- installed net framework versions again
- run net framework verification tool
Now it works.
Only problem remaining is: I can not delete the package that was causing the
error and was downloaded from Windows Update. There is a process that blocks
Is there any hint how to delete them?
What do you mean with: run net framework verification tool ?
After the new installation of .net framework - run ".net framework setup
verification tool" to ensure, that the installation is correct and working.
You can find this tool here -
And what is: net framework clean up utility ?
Right-click on My Computer & select Properties: What WinXP version is
displayed on the resulting General tab?
What application are you attempting to uninstall via Add/Remove Programs?
Look here -
bloody Microsoft must fix this issue in the update itself. Some not so good
programmer messed up and now lots of people have to deal with this bull.
I haven't yet seen any evidence that these issues are caused by a fault in the
update rather than existing issues on the affected computers. Be that as it
may, it is unlikely that Microsoft will make any changes to the .NET 3.5
installer at this point.
I am having issues installing this on a server running Windows Server 2003
SP2 - Enterprise. I have followed the information in the knowledge base
link. I have tried to contact Microsof to get help - to no avail.
Anyone have any other ideas?
I am trying to fix a problem on my dell desktop, XP. I cant seem to delete a
program in the add/remove program menu. I get an error message saying the
program failed to launch. Make a long story short- was told that my Windows
SP 3 may be corrupt to reinstall it. So, I deleted it. Downloaded the .exe
from microsoft, and when I try to install get an error message saying that
the anticipated files are not there. Error Code: 0x80070645
so what do I do now?
Do I manually try to download SP1 followed by SP2 and THEN try SP 3?

"0x80070645" means "ERROR_UNKNOWN_PRODUCT" (This action is only valid for
products that are currently installed). It could be caused by the previous

Re: Error Code: 0x80070645
Well, this is not the first time I've had to wrestle with .NET framework
update issues... I'm going to wait a bit on this one before I uninstall the
whole mess and start over like the last time. Something is just not
coordinated properly - it's the only update issue I've ever had, and here it
is again. :(
Re: Error Code: 0x80070645
Some time ago I also had this (or a very similar) problem on one of my
machines with the "update to .NET framework 3.x", after much debugging I
think I found the reason, and it WAS a Microsoft mistake (though
reporting bugs to Microsoft is always impossible thanks to the PSS idiots):
Even though the update description did not say so, the update downloaded
by Windows Update/Microsoft Update actually contained two complete and
unrelated MSI patches for two different versions of the .NET framework.
If patch#1 is irrelevant or already installed on your computer,
installing patch#1 fails and the stupid, stupid update package then
skips the needed patch#2 and reports that the entire update package
failed to install (with no reporting of the details, just a
HRESULT-wrapped hexadecimal version of a decimal MSI error code). The
next time WU/MU/AU checks for updates it again checks if patch#2 is
needed and not installed, redownloads the two-patch update package, runs
it and fails again and again and again.
So far the only workaround I could find was to uninstall ALL versions of
the .NET framework, reboot, use the ".NET Cleaner" to remove anything
not removed by the uninstall programs, reboot, manually reinstall all
the .NET frameworks and their service packs from full administrative
downloads in whichever sequence bypasses the problem, reboot, rerun
WU/MU, reboot, rerun WU/MU, reboot.
The thing Microsoft could/should do is simply put the two MSI patches
individually on WU/MU/AU (which already supports MSP files directly),
then the fact that each patch is tried on its own and the separation of
the detection for patch#1 and patch#2 should clean up the problem
Re: Error Code: 0x80070645
I have found that that is not necessary if you revert to a manual install
*and* you pay attention to the diagnostics it tries to give you if it fails.
In fact, you may find that those same diagnostics are already present
in the logs the install creates; then the only real significant effect of the
manual install is that it highlights the suggested resolution for you.
In my case it was some beta versions of the components it includes
that it wanted me to uninstall first. YMMV.
