Error 1001 during starter kit installation

[Gilbert Tordeur]

Hello.

I have downloaded "Windows Workflow Foundation Web Workflow Approvals
Starter Kit" = "WebWorkflowApprovalsStarterKit_01Nov2007b.msi" and launched
it.

I get an error : "Error 1001. This installer must be installed as an
administrator".
Here is the log (install-log.txt):
09/10/2009 17:31:50 : ====== ManageVisualStudioTemplate.Install

I am running Windows XP SP3 and I am an administrator.

I have read http://support.microsoft.com/kb/834484, but I am not able to
execute the solution because it is designed for use of Active Directory, and
I have only a home network. I have no Security tab in the folder properties.

What can I do ?

Thank you for your help,
Gilbert
