Hi, When I configured FileChecker to run as a service (checksum is on): Window Installer box will appear while Windows is loading FileChecker is listed in MSCONFIG>Services tab but not listed in Task manager's Processes or Application tab. Is that normal? If I configured FileChecker to run as a service (checksum is off), result is same as above (window installer box appear) If I configure FileChecker not to run as a service, all is well but I have to manually launch FileChecker If I added a shortcut of FileChecker in Windows Startup folder, all is well also - no Windows installer box Questions: 1. Why "Window Installer" appears if FileChecker is registered as a service? 2. How to disable splash screen of FileChecker FileChecker is installed together with all Javacool software (6) + WMP Scripting Fix enabled in WinXP Pro (SP1a) Thanks in advance.
