Make WIX installer place files in AppData

Question

I'm writing a dapp for ethereum client for windows. In order to make dapp available for user I have to place specific files in the folder in appdata. So I just should place some files in %appdata%\Parity\Ethereum\dapps\mydappname. But I always get weird errors with WIX, the last one is

Error 93 ICE64: The directory dapp is in the user profile but is not listed in the RemoveFile table.

I have following myapp.wixproj

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" InitialTargets="EnsureWixToolsetInstalled" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

And following wxs:

                    </Directory>
                </Directory>
            </Directory>
        </Directory>
    </Fragment>
    <Fragment>
        <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER"></ComponentGroup>
    </Fragment>
</Wix>

I found that I have to use heat task to create a correct files tree, but now I'm stuck with simple task "copy these files on user machine".

Answer 1

I am unfamiliar with this type of application (dapp for ethereum client for windows) - so the advice has to be generic I am afraid.

Per-User Files & Registry Settings: In general deploying files to the user profile and HKCU settings is difficult with MSI. As Chris points out it basically just works for the user installing the MSI, unless you actively add constructs to get files copied to all user profiles, and even then it is sort of clunky.

Approaches: I wrote a long answer a long time ago on the subject: Create folder and file on Current user profile, from Admin Profile (long and elaborate, but without any automagic solutions).

Preferred Approach: Before getting involved in too much complexity, the easiest approach is generally to use your application to copy the userprofile files in place for every user on first launch - instead of using the setup to install user-specific files.

This requires that there is a separate application executable to launch, generally via its own shortcut - which it might not be? It generally does not work for addins for example.

• Approach 1: Install template files per-machine and then copy them to each user's userprofile on application launch.

• Approach 2: Alternatively I like to download files directly from a server or database and put in the userprofile - also on first launch.

Apply Updates?: There are ways to ensure that you can re-copy files if there are changes to your templates as described here: http://forum.installsite.net/index.php?showtopic=21552 (Feb 2019 converted to WayBack Machine link).

Errors: The specific problem you report has to do with the need for a per-user registry key path and a RemoveFolder entry for all folders targeting userprofile locations:

  <Directory Id="AppDataFolder">
    <Directory Id="Parity">
      <Directory Id="dapps">
        <Directory Id="INSTALLFOLDER" Name="F2">
          <Component Guid="{77777777-7777-7777-7777-7777777777DD}" Feature="MainApplication">

            <RegistryKey Root="HKCU" Key="Software\TestManufacturer\TestApp">
              <RegistryValue Name="Flag" Value="1" Type="string" KeyPath="yes" />
            </RegistryKey>

            <RemoveFolder Id="RemoveINSTALLFOLDER" Directory="INSTALLFOLDER" On="uninstall" />
            <RemoveFolder Id="RemoveParity" Directory="Parity" On="uninstall" />
            <RemoveFolder Id="Removedapps" Directory="dapps" On="uninstall" />

            <File Source="Test.exe" />
          </Component>
        </Directory>
      </Directory>

This is just one of MSI's conventions and quirks. As already stated, install all files per-machine and copy them to the userprofile with the application instead. It will dis-entangle them from any setup interference in the future. Then you do not need to deal with these RemoveFolder issues.

• WiX Installer - Children of LocalAppDataFolder installed to wrong location after UAC prompt

Answer 2

I've found and verified that the solution is working when adding a CustomAction which uses PowerShell to iterate over all user profiles and copies a "template appdata folder" to them. The template folder is shipped and installed by the WIX MSI installer to [ProductDir]appdata, e.g "C:\Program Files (x86)\myApplication\appdata".

Here's what I've put to as a CustomAction to the WXS WIX script to achieve this:

<CustomAction 
    Id="ExecPsXcopyCmd" 
    Directory='ProductDir' 
    Execute='deferred' 
    Impersonate='no' 
    ExeCommand='[SystemFolder]WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy "ByPass" -Command "$productDir = &apos;[ProductDir]&apos;; $userRoot = (Split-Path $Env:PUBLIC); Foreach ($profile in Get-ChildItem -Path $userRoot -Directory -Exclude &apos;Public&apos; -Force -ErrorAction SilentlyContinue) { $srcPath = Join-Path -Path $productDir -ChildPath &apos;appdata&apos;; $dstPath = Join-Path -Path $profile.Fullname -ChildPath &apos;AppData\Roaming\myApplication&apos;; xcopy /S /E /I /R /H /Y $srcPath $dstPath}"'
    Return='check'/>

<InstallExecuteSequence>
    <RemoveExistingProducts Before="InstallInitialize" />
    <Custom Action="ExecPsXcopyCmd" After="WriteRegistryValues">NOT REMOVE</Custom>
    <LaunchConditions After="AppSearch"/>
</InstallExecuteSequence>

This assumes your product installation directory is called "ProductDir".
