Windows applications are typically installed in 2 separate directories, as follows :



Program Files Directory


The start-up screen and the update mechanism are located in the Program Files folder, typically C:\Program Files\

 C:\Program Files (x86)\MCC Pilotlog
Version 4.0 - mccPILOTLOG

The launch application is named mccPILOTLOG.exe (Version 3.6) - mccPILOTLOGLauncher.exe (Version 4.0)


You should never move mccPILOTLOG outside the program files directory. Verify the desktop icon properties (right-mouse click) and make sure that it points to the above mentioned executable.

File Download / Upload Errors


mccPILOTLOG requires that the main application is stored in the default C:\Users\your-name\ folder.  If the application is stored in a different folder, without telling mccPILOTLOG about it, the software will throw a number of errors, such as :

  • File Download Error
  • mccCLOUD Download Error
  • INI Config File Error
  • Cannot find Source File
  • Run Time Error 53
  • Run Time Error 75
  • Run Time Error 76


Do the following :


  1. Copy the Application Data Directory link from the above table
  2. Open File Explorer in Windows and paste the link inside the address bar at the top, and hit the Enter key


Notice that %username% is automatically turned into your Windows User Account name, e.g. C:\Users\Miguel Sanchez\AppData\Roaming\MCC Pilotlog\


If File Explorer cannot find the folder :


  • You may have installed mccPILOTLOG with your Administrator Account and the main application is therefore stored in C:\Users\Admin\AppData\Roaming\
  • You are running Windows with a different User Account (e.g. user account from your company, or user account from your partner)
  • Or, the User Directory is located elsewhere, like   D:\Users\Miguel Sanchez\...


You must then notify mccPILOTLOG that your main application is stored in a different folder.  Continue with the following solution :




If File Explorer can find the folder, but mccPILOTLOG cannot write in the folder :


  • You are running Windows with a different User Account (e.g. user account from your company, or user account from your partner)
  • Or, you may not have Administrator Rights in the current User Directory


You must verify your User Rights and run the application as Administrator.  Continue with the following solution :
