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\Win dows\Safer\CodeIdentifiers
PolicyScope, and then change the setting from 0 to 1.
6. Restarted the computer.
