Right click on C:\Program Files\iVMS-4200 Station folder, go to "Security" settings, add "Everyone" (or the current user) to have full rights and Apply. Then go "Advanced", select "Everyone" and check "Replace all child .. bla bla" and OK.
This way give the current user or "Everyone" full rights to create/delete/modify the files under "Ivms4200" folder.
I still don't know why the fu**ng Windows don't give full rights to the folder of the current user, when an application is installed with "Run as administrator".
