**IMPORTANT: I am using XP HOME, so none of the regular methods of correcting this issue work for me because they rely on changing things in IIS, which I do not have on my machine. For example, Microsoft's KB# 329291 says that it applies to Microsoft Internet Information Services 5.0 andMicrosoft Internet Information Services 6.0. Clearly that doesn't help a user of XP Home.**

The Issue:

I have administrator rights on my XP Home machine (with all the latest patches including SP3), which I have been using for developing asp.net 3.5 web sites with VWDExpress 2008. I have SP1 for the asp.net 3.5 installed. A few months ago, I started getting error messages when trying to install certain programs, including the ASP.NET Small Business template from the ASP.NET web site, Turbo Tax Updater, an several others. All of them return an error message (see below for an example) that I do not have permission to install this application and that I need to contact my system administrator.

I am not sure, but the issue may have started around the time that XP SP3 came out.

Is there a fix that a mere mortal (not a real programmer) can use to fix this or do I need to go out and buy XP Pro so that I have access to the IIS tools? (In which case I'll probably wait and buy Windows 7 SP1.)

Thanks in advance, especially if you reply in plain english!

Example error message - this one from the Microsoft Small Business aspx template installation attempt:

Application attempted to perform an operation not allowed by the security policy. To grant this application the required permission, contact your system administrator or use the Microsoft.NET Framework Configuration tool...

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
