Try uninstalling the Store module to see if that takes care of the issue.  This does not appear to be a Vista issue, but a Store module issue.  If you can then compile your project, then download the lastest store module and resinstall to see if the issues comes back,  If it does then please post this as an issue in the stores issues tracker located at http://support.dotnetnuke.com/Main.aspx.

Post the issue in the Public dotnetnuke project and in the title or description state that this is an issue with the store module.  The team leader will then get it moved to the Store project.  Unless you need the store module, I'd suggest just uninstalling the module for know, so you can get you local site up and running. You also might want to try downloading the previous version of the store module to see if it installs correctly.

Actually the store module was written in C# hence the .cs files for this problem.
