I am a new user of Visilogic and installed the latest version in Windows 8.1.

I experience the following:


1. Permission 9 denied - When trying to open the program

2. When I manage to open the program I can save but if I try to open the file the program crash.

3. Sometimes I get the message "application is running" when I try to open Visilogic.


When I now try to uninstall i get: "An error occurred while launching the setup. the remote procedure call failed"


Any advice would be great.

Please note – for Windows 7 /8 / 8.1 install the software while the Windows UAC is OFF and after rebooting the PC.

Please reinstall VisiLogic as follow:

Close VisiLogic (if necessary, do it from Windows Task manager)


  1. Backup your projects and delete all the files related to Unitronics installations.
  2. Erase the “Unitronics VisiLogic_C”  folder  from- C:\Program Files\Unitronics
  3. Erase the “Unitronics”  folder  from- C:\Program Files\Common Files.
  4. Perform Windows update and restart the PC
  5. Log-on as administrator

Save the setup file on your desktop and make sure that the installation file is not blocked (Right click on the file>Properties) If yes, just click on the unblock button:



Install VisiLogic.


If software opened properly, Go to the properties of VisiLogic shortcut and under compatibility ticked verify the Privilege Level “Run this program as an administrator”.


I hope it helps..
