Wix Installer error "DLL required for this installation to complete"

When I run the installer I get this error: There is a problem with this Windows Installer package. A DLL required to complete this installation could not be started. Any hint?

Your question has two answers.

First answer: shared DLL

When configuring a custom action, an attribute appears DllEntry="WixQuietExec"

. You have to package the DLL with this code:

<Binary Id="WixCA" SourceFile="WixQuietExec.dll" />

This tag must be created internally Product

.

So your code will be like this:

...
<Binary Id="WixCA" SourceFile="WixQuietExec.dll" />
<CustomAction Id="QtExecDeferredExample" BinaryKey="WixCA" DllEntry="WixQuietExec"
              Execute="deferred" Return="check" Impersonate="no" />
...


Don't forget to include CustomAction[BinaryKey]

and Binary[Id]

.

Second answer: WixUtilExtension

In particular, for a standard custom action like QtExec , you only need to provide a link to the extension.

  • In Solution Explorer, expand the links in your project
  • Right click on it and select Add Link
  • Find the folder where the WiX Toolkit is installed. Then select the bin folder. In my case, the full path isC:\Program Files (x86)\WiX Toolset v3.8\bin

  • Select WixUtilExtension.dll and click "Add" and then "OK"

Modify the tag Wix

by adding xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"

. For example, your tag would be:

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:util="http://schemas.microsoft.com/wix/UtilExtension">

Try changing DllEntry

from WixQuietExec

to CAQuietExec

and using the propertyQtExecCmdLine



refer to https://www.firegiant.com/wix/tutorial/standard-libraries/silence-please/

I faced the same problem (error 1157) when I switched from using the CAQuietExec extension to WixQuietExec. I was using Wix Toolset 3.9 when the error occurred.

I solved this problem by installing Wix Toolset 3.10.1 (this is the latest stable version now) and the WixQuietExec extension works as expected.

For anyone who comes across this issue while developing a custom action using C #, I suggest making sure that

  1. The BinaryKey refers to the generated * .CA.dll and not the actual DLL file.
  2. Make sure the called method has the [CustomAction] attribute.
