DllRegisterServer returns 0x80020009 when trying to register a dll

When I try to run the command: "regsvr32 dllname.dll" for a specific dll, I get a popup with an error message saying that DllRegisterServer returned 0x80020009. I've googled all over the Internet, and come up with 2 possibilities:

1) dllname.dll depends on other dlls which are not registered on the user's machine
2) Even though the user has admin rights to their PC, they still are restricted from using certain registry keys that dllname.dll needs to write to.

I don't think the problem is #1, because I removed a few dlls that dllname.dll is dependent on, and when I run regsvr32 dllname.dll on a PC that doesn't have the original problem, I get a different error code: 7e. Has anyone come across this problem, and do you know the solution? This happens on an XP PC, and it's only happening on 1 out of 10 PCs. The other 9 PCs have no problem registering dllname.dll.

The error can be resolved if you can re-register the dll file. That is the only way to fix the issue and you can do that through command prompt using regsvr32 command. This is one of the most easiest way to fix the problem. But if that does not work then the only option left here is to run a repair setup of windows. You can use the windows installation disc and hit R from boot. That will run the repair setup and it is one of the best way to get rid of problems that you are facing.

Wow, thanks for the quick response, Mark! I've been pulling my hair out trying to fix this problem. I only have access to a PC right now that has regedit.exe, so I don't see any Permissions item, but you're saying regedt32.exe has that item for any PC it's running on?

I get this issue with clients a lot. It always turns out that they are not using xp, but vista. If it is vista (blue orb instead of green start button), the easiest way to fix it is to run the CMD.exe as Administrator.

Steps:

Start> Computer> Local Disk (c:)> Windows> System32> Scroll down to CMD.exe, right click and 'Run as Administrator'

Then you can just regsvr32 xxxxx.dll

to change directory use the following format:
to go back a folder - CD..
to navigate forward - cd folderNameExactly

Thank you very much, it solved the problem on windows7 too :)

When I try to run the command: "regsvr32 dllname.dll" for a capicom.dll, I get a popup with an error message saying that DllRegisterServer returned 0x80020009.
Kindly help me on this issue...

Hi,

In order to resolve this issue, you can also do the following:

Restore file and registry security permissions to a known state.

For Windows XP users:
Download and unzip a small utility called Repair Permissions from http://djlizard.net/software/Repair%20Permissions.zip
Locate the unzipped folder, and double-click the !RUNME file.
The command prompt window will now open and will begin to restore the file and registry permissions to a known state, please be patient as the command can take some time to complete.
Once the command has completed, try to register a dll file again.

For Windows Vista/Windows 7 users:
Click Start>All Programs>Accessories, then right-click on “Command Prompt” and select “Run as Administrator”
Type in the following command exactly as you see it and press ENTER.
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
Wait for the command to complete, it can take some time so please be patient.
Once the command has completed, try to register a dll file again.

I am having a similar problem trying to run a program in windows 7. I ran your code above and received the following error message:

The task has completed with an error. See Log %windir%\security\logs\scesrv.log

The error log is quit long, but it appears that certain securities are not set up. My machine will not allow me to create a restore point and I wonder if the 2 are related. I'm in over my head here and any advice would greatly help.

Log highlights (I can provide more info if needed);
