卸载完成后如何在 Wix 中执行自定义操作

Question

I have enabled logging using below code:

<Property Id="MsiLogging" Value="voicewarmupx!"/>

and I want to copy log file from temp folder to custom Log location. I have written a custom action as below

<CustomAction Id="CopyLogFile" Execute="immediate"
          ExeCommand="cmd /c copy [MsiLogFileLocation] [LogsFolder]"
          Directory="TARGETDIR" 
          Impersonate="no" 
          Return="asyncNoWait" />
<InstallExecuteSequence>
  Custom Action="CopyLogFile" OnExit="success"></Custom>

After successful installation above code works fine but when I do Uninstall the code is not working.

Any one please help me to move file from Temp folder to specific folder after uninstall.?

Answer 1

The specify the condition for the Custom Action to be invoked on an uninstall: (REMOVE="ALL") AND NOT UPGRADINGPRODUCTCODE .

This should work:

<CustomAction Id="CopyLogFile" Execute="immediate"
          ExeCommand="cmd /c copy [MsiLogFileLocation] [LogsFolder]"
          Directory="TARGETDIR" 
          Impersonate="no" 
          Return="asyncNoWait" />

<InstallExecuteSequence>
  <Custom Action="CopyLogFile" OnExit="success">(REMOVE="ALL") AND NOT UPGRADINGPRODUCTCODE</Custom>
...
