Wix Installer unable to start service

Question

I created a Wix setup to install a service. There is my product.wxs :

<?xml version="1.0" encoding="UTF-8"?>
<?define compagny = "MyCompagny"?>
<?define product = "My Service"?>
<?define service = "MyService"?>
<?define version = "!(bind.FileVersion.MyService.exe)"?>

        </Directory>

    <ComponentGroup Id="InstallComponents">
      <Component Id="InstallService" Guid="XXXXXXX" Directory="INSTALLFOLDER">

When I try to install my service, I have error :

Service 'My Service' (MyService) failed to start. Verify that you have sufficient privileges to start system services

I saw that this error is a generic error. So I ignored it. In my INSTALLFOLDER I have all files. Then I started services.msc and try to start my service. The error is :

Cannot start the service on local computer. Error 193:0xc1

I try to have more details, but I can't find what is the problem. How can I fix this ?

Answer 1

I finally found what was wrong.

In me service properties, I saw that the service path was pointing on MyService.exe.config.

I fixed the problem by adding KeyPath on .exe :

<File Id="MyService.exe"
      Name="$(var.service).exe"
      Source="$(var.MyService.TargetDir)\$(var.service).exe"
      Vital="yes"
      KeyPath="yes"/>
