I have wix installer with bootstraper for some application what creates additional files in application folder during his work and I have to remove these files during uninstall. According to https://www.hass.de/content/wix-how-use-removefolderex-your-xml-scripts and other same examples I have next parts of code:

  1. Define property:

    <Property Id="APPLICATIONFOLDER">
  <RegistrySearch Key="SOFTWARE\ProductName" 
                  Root="HKLM" 
                  Type="raw" 
                  Id="APPLICATIONFOLDER_REGSEARCH" 
                  Name="Path" />
</Property>

  2. Define component:

    <Directory Id="APPLICATIONFOLDER" Name="ProductName">
  <Component Id="RemoveAll" Guid="some-guid">
    <RegistryValue Root="HKLM" 
                   Key="Software\ProductName" 
                   Type="string" 
                   Name="Path" 
                   Value="[APPLICATIONFOLDER]" 
                   KeyPath="yes"/>
    <util:RemoveFolderEx On="uninstall" 
                         Property="APPLICATIONFOLDER" />
  </Component>
</Directory>

  3. Add component to feature:

    <Feature Id="ProductFeature" Title="ProductName" Level="1">
  ...
  <ComponentRef Id="RemoveAll" />
  ...
</Feature>

Then when I try to uninstall this application I have next lines in wix logs:

...
MSI (s) (B4:64) [13:05:58:798]: PROPERTY CHANGE: Adding APPLICATIONFOLDER property. Its value is 'C:\Program Files(x86)\ProductName\'
...
Action start 13:05:58: WixRemoveFoldersEx.
MSI (s) (B4:48) [13:05:58:914]: PROPERTY CHANGE: Adding _APPLICATIONFOLDER_0 property. Its value is 'C:\Program Files (x86)\ProductName\'.
WixRemoveFoldersEx:  Recursing path: C:\Program Files (x86)\ProductName\ for row: wrfE932DA8DA501DD981493D5D9F4EFDD75.
MSI (s) (B4:64) [13:05:58:918]: Doing action: CostInitialize
MSI (s) (B4:64) [13:05:58:918]: Note: 1: 2205 2:  3: ActionText 
Action ended 13:05:58: WixRemoveFoldersEx. Return value 1.
...

But nothing heppens and all additional files are present in the application folder, and accordingly the folder also is present. I have no idea why and I do not know what need to change to resolve this problem.

Could somebody help me?

You need to remove any files created by the application before the folder can be removed. Try something like this:

<Component Id="RemoveOrphanFiles" Guid=InsertGUID KeyPath="yes">
   <RemoveFile Id="RemoveFiles" Name="*.*" On="uninstall" />
</Component>

and add a condition so that it only runs on uninstall ... Hope this helps!

    `util:RemoveFolderEx`'s purpose is to remove all files and folders in a folder without knowing all the names. – Alexander Aug 30 '18 at 14:59
