See this Comm Center thread. Inside Visual PinPoint, a folder path is created at startup which points to the same folder as the one Visual PinPoint.exe is installed to. This is where it both creates and opens Solve.txt in Notepad. The same exact path/string is used to create the file as well as commanding Notepad to open it. By the error message you see in Notepad, you can see it is C:\Program Files\PinPoint\Solve.txt (it could be Program Files (x86) if you have a 64 bit system).
However, the Solve.txt file is created in
C:\Users\YourUsername\AppData\Local\VirtualStore\Program Files\PinPoint
(again, it could be Program Files (x86)). So Windows 7 is redirecting the file creation to that place outside of Visual PinPoint.
Probable solution is to use a shell special folder (user's tempfile folder, e.g.) for that location.
