When you try to run PowerBuilder Installer / InfoMaker Installer, it is possible that some anti-virus software will falsely detect a virus or problem in the installer, and then the product fails to install.
You can be affirmed that the PowerBuilder/InfoMaker Installer is digitally signed by “Appeon Inc.” and the files to be installed by the installer are free of adware, spyware or any form of malware.  If your anti-software is having issues with any of Appeon product installation, please read through this article for a feasible solution.

False Detection Symptoms

Depending on the anti-virus software you use, the following are possible false detection symptoms you may be experiencing:

  • (Major issue) Avira: PowerBuilder 2019 R3 Beta fail to be installed. The anti-virus software will remove the whole Appeon folder. Appeon is currently working with Avira to fix the issue.
  • (Major issue) Norton 360: PowerBuilder 2019 R3 Beta may fail to install. Appeon is currently working with Norton to fix the issue.
  • Windows Defender SmartScreen: You are warned that the app (installer) is unrecognized. With Windows Defender SmartScreen, if a downloaded program does not have established reputation (for example, the program is newly available and has not been downloaded by many users), it tends to warn you that the program is an unrecognized app.
  • Avast, AVG, F-Secure and Kaspersky: PowerClient apps are blocked, and can then successfully run if added to exceptions list.
  • F-Secure, Kaspersky and McAfee: .NET Framework 4.8 fails to install, and can be successfully installed after you restart the computer.
  • McAfee: The file “PowerClientAppSetup.exe” is blocked, and can successfully run after you choose "Allow the risk".
  • BitDefender: Files are quarantined with “avc” as the reason and the file “IisController.exe” is blocked.
  • BullGuard: (1) The file “IisController.exe” is blocked. (2) The installer file "PowerBuilderruntime.exe" is blocked.
  • Panda Dome: The installer files “PowerBuilderInstaller_bootstrapper.exe” and “InfoMakerInstaller_bootstrapper.exe” are both blocked.
  • Sophos: The file “ejb2pb190.exe” is blocked.
  • PCProtect, Total AV: When you run a PowerClient app hosted on a different computer, the file “pbvm.dll” and "pbshr.dll" are blocked. After you add the two files as exceptions, the app will run successfully.


When the installer fails to run, we recommend that you can take these steps:

  1. If the antivirus or Windows Defender SmartScreen gives you the “Run Anyway” option or allows you to add the blocked file to the exceptions list, you can take the option and proceed with the installation.

  2. Obtain the latest malware definitions of the antivirus or Windows Defender SmartScreen. 

    For example, with Windows Defender SmartScreen, you can follow the steps below to clear cached detection and obtain the latest malware definitions.

    • Open command prompt as administrator and change directory to c:\Program Files\Windows Defender

    • Run “MpCmdRun.exe -removedefinitions -dynamicsignatures”

    • Run "MpCmdRun.exe -SignatureUpdate"

  1. Change the settings in your anti-virus software to add the files from Appeon installer to the exceptions list. If you are not familiar with how to add exceptions, you may need to contact the anti-virus software support or check the relevant documentation.

  2. (Optional) Report the issue to Appeon Support. Appeon Support will promptly provide you all necessary assistance, and request the anti-virus software support to remove the false positives.
