When installing the software in the standard windows programs folder one can not start it via the start menu any more. This is due to the fact that the software needs write access to the programs folder, which is only given when being logged in as administrator and starting the exe with administrative rights.
The software should be altered so that any file, which has to have read/write access should be placed in windows APPDATA folder in:
C:\User\Username\AppData\Roaming
Access is always done via the %APPDATA% folder property in windows development environments.
