When you launch you Visual Studio 6.0 IDE, make sure you right click the icon and select "Run As Administrator" instead of just running it normally, you can also right click the shortcut icon, select properties, and in the Compatability tab, you should be able to check "Run As Administrator" so that every time you click the shortcut for Visual Basic 6.0, it will run in admin mode (and may ask/prompt you every time, in which case, you must select Yes). In this case, the File/Path access error will go away :).
Let me know how you get along and if you need more help.
