Multicam does not start

Symptoms : The user starts Multicam Suite, logo appears in red like usual but then nothing happens. No multicam.exe in the task manager either.

Cause : WMI (Windows management instrumentation) corruption

How to verify ?

Open a powershell window by typing "powershell" in the Windows search bar.

Type the following command : 

Get-WmiObject -query "SELECT * FROM Win32_OperatingSystem"

The command should return something similar :

If it returns an error like this, WMI is corrupted.

You can also open the WMI control panel with Win+R and type wmimgmt.msc

Right click on the WMI control > properties > wait a few seconds

If it displays your hardware configuration, WMI is ok. If an error is displayed instead, WMI is corrupted or dammaged.

Solution : download the following batch script WMI_fix.bat If this does not work, try the archive version WMI_fix.zip

NOTE : some antivirus can detect the script as a malicious file because of its nature (batch file). It is not.

Run the script as an admin, let it run for a few minutes. Then restart the computer and launch Multicam again.
