Simple solution to problem I was researching for a day or so.
Step 5 was all I needed to change and no reboot.

(Full error code is 0x80070643
Visual Studio 2005 Service Pack 1, SP1 )

I am running Windows Server 2003 SP1 and Visual Studio Professional and had
the same problem and error message that you are experiencing and this fixed
the issue for me. I did the following:

1. Click Start, click Run, type control admintools, and then click OK.
2. Double-click Local Security Policy.
3. Click Software Restriction Policies.

Note If no software restrictions are listed, right-click Software
Restriction Policies, and then click Create New Policy.
4. Under Object Type, double-click Enforcement.
5. Click All users except local administrators, and then click OK.

I then changed
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Safer\CodeIdentifiers
PolicyScope, and then change the setting from 0 to 1.

6. Restarted the computer.
