When trying to open the Backup Pro GUI, the following is reported "System Error. Code: 2. The system cannot find the file specified".
The javaw.exe process is launched when opening the backup client GUI.
This file exists, and antivirus software has been eliminated as a cause.
Image File Execution Options have been configured. This is used for debugging in Visual Studio, so it may have been set up for debugging another application (not Backup Pro) using a third-party tuneup or debugging application, and is now clashing with the Backup Pro installation.
Check the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\javaw.exe
A debugger entry may exist, for example:
Debugger"="\"C:\\Program Files (x86)\\AVG\\AVG PC TuneUp\\TUAutoReactivator32.exe\"
Delete the entire javaw.exe registry key. The javaw.exe process should now run without referring to the debugging environment.
