Can't install on Server 2008

Hello.  I'm trying to install the FileVista.msi file on my x64 Server 2008 file server (so, IIS 7.0) which tells me I have .net 2.0 installed.  When I click on the .msi I immediately get an error message "Installation Incomplete - the installer was interrupted before FileVista could be installed.  You need to restart the installer to try again."  Which doesn't work.  Any ideas?  I'd really like to get this working!

Please see Access Denied..

Hi, thanks for the tip.  It installed, but when I try to browse the site I get:

HTTP Error 500.19 - Internal Server Error

Module IIS Web Core 
Notification BeginRequest 
Handler Not yet determined 
Error Code 0x80070021 
Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".  
Config File \\?\C:\inetpub\wwwroot\FileVista\web.config 
Requested URL http://localhost:80/FileVista 
Physical Path C:\inetpub\wwwroot\FileVista 
Logon Method Not yet determined 
Logon User Not yet determined 


I think the problem here might be that I don't know what the hell I'm doing.  How would I go about getting help to set this up since I'm clearly too incompetent?

Thanks for your help

Please first make sure if ASP.NET is installed on IIS. Open "Turn Windows Features on or Off" option in the Control Panel and go to Internet Information Services > World Wide Web Services > Application Development Features section and see if "ASP.NET" option is checked.

If it's already checked, then you may need to run some commands to unlock configuration sections. 

The most common problem may be requestFiltering section so run the following command:

%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/security/requestFiltering

If this still does not solve the problem and look at the error message titled HTTP Error 500.19 carefully, in "Config Source" section there should be the configuration section name highlighted in red which caused the error.

So run the command to unlock the highlighted section in question. For example if it's "modules" run

%windir%\system32\inetsrv\appcmd.exe unlock config /section:system.webserver/modules

You can see a list of section names with this command

%windir%\system32\inetsrv\appcmd.exe unlock config /section:?

really sorry about this, but I've managed to get as far as the setup page.  Put the admin password in and it's not being accepted.  I seem to have locked myself out of it.  a - I clearly shouldn't be allowed near a computer and b - is there any way of resetting it or changing the admin password without having an admin password?  thanks.

Hello.  Can I bump this please.  I'd really like to get this resolved and working asap.  Thanks.

Hi Sean,
I guess you have not created any users or root folders yet so you have no data to lose. The best way would be to uninstall FileVista from control panel. Then you can reinstall and run the configuration wizard again. This way you can choose a new admin password.
