ShellExecuteEx error 299 when launching installer created with Inno Setup

Question

I use Inno Setup to create my first installer.
But when the installer is launched, before having the windows screen asking the permission to execute this file, I get a window with this error:

ShellExecuteEx a échoué : code 299
Seule une partie d'une requete ReadProcessMemory ou WriteProcessMemory a été effectuée.

English (from WinError.h):

ERROR_PARTIAL_COPY - Only part of a ReadProcessMemory or WriteProcessMemory request was completed.

And then the installer is launched. But, after about 10 sec, it launches again on its own.

Here is my iss file:

; Script generated by the Inno Script Studio Wizard.

#define MyAppName "Facturation"
#define MyAppVersion "1.0"
#define MyAppPublisher "JoWe"
#define MyAppURL "http://www.jowe.fr/"
#define MyAppExeName "facturation.exe"

I have this problem even when I create an new installer with the wizard. I have added a log to the Inno Studio, but it only have the log of the compilation, where there is no error.

Does anyone know where this problem comes from?

A co-worker ran into the same issue. It turned out that the Virus scan, Avast, was the cause. Disabling the virus scan, then installer ran without any issue.
