FCRemove.exe for FortiClient v7.4.5

A couple days ago, I helped one of my clients with installing the FortiClient v7.4.5 on his computer using the FortiClientSetup_7.4.5_x64.exe file. But after the setup process was completed, we noticed that the domain name was not correct; it was showing the domain name of his current company that he works for instead of the domain name of his contractor’s company. So I tried to uninstall the program from Windows Control Panel → Programs and Features → Select FortiClient, but it did not let me uninstall the program. I tried clicking the Repair button, too, but it also did not work.

I tried browsing to https://support.fortinet.com -> Support -> Firmware Downloads -> Products, but I got the following message:
 

Sorry, you don't have any product covered by Fortinet support contract.

Please contact Fortinet partners to purchase Fortinet support contract or Fortinet customer service team at cs@fortinet.com.

And I asked my client if he knew who to contact to download the FortiClientTools zip file, and he told me that he did not.

Can you please attach the FCRemove.exe file for the FortiClient v7.4.5?

Thank you in advance.
