Regsvr32 error 0x80004005

Whilst running regsvr32 for an ocx component I get an error 'the module
'blah.ocx' was loaded but the call to DllRegisterServer failed with error
code 0x80004005.

Any ideas anyone ?

0x80004005 denotes "Access is denied" error. See if running the Regsvr32 command-line from an elevated Command Prompt helps.

What the hell is an "elevated Command prompt"? I do have the same problem.

You simply right click the Command Prompt shoercut and select Run As
Administrator from the pop-up menu.

Open a command box as administrator... right click the icon and select
the "Run as Administrator" option.

May be a registry permissions issue. Use Regmon or Process Monitor to track.

The error message was the same. I tried running as an admin, logged on as an admin, no such luck. First time I have seen this. Trying to setup muvpn on vista.

regsvr32.exe C:\Windows\System32\irebase.dll returns error "irebase was loaded but the call to DllRegisterServer failed with the error0x80004005

I am having the same problem as mentioned here. I do not have command
prompt icon. ? I tried to run the command (regsvr32
path\vbscript.dll) from the 'DOS' command prompt but am unsuccessful.
How can I run this as an administrator?

To open an elevated Command Prompt, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

I had the same problem. Running the command prompt as administrator
worked for me as well. I was surprised though, because my user is part
of the adminstrators group. Does anyone know what the difference is
between running as administrator and being part of the administrators
group? I thought they had the same level of priviledges.

Hi Brian,

This is a major change in Windows Vista. Although the user may be part of the Administrators group, they run in standard user mode. When a system-wide operation is performed, the elevation dialog is shown. In case of legacy applications (that don't have the requireAdministrator flag set in the manifest), the user need to right-click on the program and choose "Run as Administrator".

This problem may occur if a file that the Windows Product Activation (WPA) requires is damaged or missing. This behavior occurs if one or both of the following conditions are true:

• A third-party backup utility or an antivirus program interferes with the installation of Windows XP.
• A file that WPA requires is manually modified

you can try this Error code 0x80004005 in windows vista

While running regsvr32 for registering a vb6 application dll i got an
error message "DllRegisterServer failed with error code 0x80004005."

Any ideas anyone ?

It will work fine if you turn off User Account Control.
