Error: "The following applications should be closed before continuing the install.", from my custom code with /qn parameter

[tanya]

Hello,

I develop desktop software. My software has updates funtionality.
I call installation (.exe) from my custom code with /qn parameter for installaing updates.
When intallation is run the following error occures: The following applications should be closed before continuing the install.
When installing the same application not from my custom application (but by clicking .exe) and without /qn flag no issues occur.
What is the reason of Kaspersky error exactly in this case and is it possible to avoid it?

Looking forward to hearing from you.

Best regards,
Tanya
