How to fix Class not registered or 80040154 error reviews

worked on a windows xp professional.

i found class not registered in attendance management software. I format and installed a new software but again same problem is detected what can I do plz help me

Windows 10 error message:
"The module "quartz.dll" was loaded but the call to DllRegisterServer failed with error code 0x80070005.

For more information about this problem, search online using the error code as a search term."

It didn't fix my problem but gave a error message as everyone else who have commented.I use windows 7 ultimate

This didn't work for me because I still get an error message that says: "Quartz DLL was loaded but call to DLL Register Server failed with error code 0x80070005. Now what???

didn't work on win 7

The opening paragraph said there were several easy fixes. Only one was given.

I did the recommended fix successfully, but that did not remedy the problem. What other commands can I run to try to fix this? Thank you.

Class not registerd when I try to save-as in MS Word or Open Office. Your fix had no effect, but got confirmation register server succeeded.

Rebooted, my problem not solved.

thanks...

I have been receiving the following message when I try to play anything with MPC-HC:

"Failed to query the needed interfaces for playback". With WMP I get the message "The specified module could not be found".

After much Googling I realized that quartz.dll is not registered on my machine. I confirmed that this is so by using the InstalledCodec program.

I tried registering it with "regsvr32 quartz.dll", but I have the error message "DllRegisterServer in quartz.dll failed. Return code was 0x8007007e".

I suppose the next step is to delete the existing quartz.dll in System32 and copy another version downloaded from the internet.

That means defeating System File Protection.

Not working :(

Nice try but I then got the message that quartz.dll was loaded but the call to DllRegisterServer failed with error 0x80070005 :(
Off to try googling that now...

it worked perfectly =D

I tried the 'quartz.dll' and it worked. I also tried the 'ieframe.dll' and it did not work. Is there a reason?

Tried to play Pogo & got error 'Class not registered'. During my trying, message says download Explorer 8 because doing away with 7.

I did E8, wouldn't work so deleted it. THEN I got the Class not registered message. Now nothing will come up.
