DLPC4422-SW: Unable to properly install the DLPC4422GUI

Part Number: DLPC4422-SW

Hi TI,

I tried several time to install DLPC4422GUI using, for example, the link below:


The file is downloading without problem and I can launch the installation (screenshot below).



Sadly, each time I clicked next, the installation stopped and displayed the following error message:


In addition, my antivirus (Avira), signaled an HEUR virus and promptly put the file in quarantine.

Have you ever encounter this problem ?

Do you think it is coming from my antivirus or from the file ?


  • Greetings Guillaume,

    We have not seen this issue or had it reported before.  To verify, I downloaded the .exe from  It installs fine and Symantec detects no issues.  This is on a Windows 10 Pro x64 system with Symantec Endpoint Protection.

    I submitted the installer exe to Avira's online analysis as a possible false positive; their system responded that the exe is clean (I don't know what they check).

    I suspect that Avira is detecting a heuristic false positive during the install and is deleting or quarantining the file, which causes the installer error.  Is it possible to try the installation with heuristic detection disabled or reduced?


  • Hi Gary,

    It worked well by desactivating Avira.

    Thank for pointing out the false positive !
