[wix-users] Error when removing msi

[Hoover, Jacob]

1) Seems sketchy / fragile at best, but if one must do it, write a few CA’s to handle the install/rollback/upgrade/remove cases.
2) standard WIX/Windows installer abilities - https://wixtoolset.org/documentation/manual/v3/howtos/files_and_registry/add_a_file.html
3) https://wixtoolset.org/documentation/manual/v3/howtos/general/install_windows_service.html

As always,  https://www.firegiant.com/ <https://www.firegiant.com/>  can help you out if you are looking for a solution and don’t want to go through the pains of the learning curve (or don’t have the time).

Hi Jacob,

Thanks for your reply. Sorry I am very new to wix.

 Actually my requirement was,

1) Add an entry in windows/drivers/etc/hosts file.
2) Put files in a folder.
3) Remove an windows service if exist and re install it.

I found on web I can use cmd. What else I can use?

Exe based CA’s are ugly at best.  Is there a reason you can’t author the changes as standard MSI actions?

Subject: [wix-users] Error when removing msi



Dear,
I have the following,
  <InstallExecuteSequence>      <Custom Action="ExecInstallService" Before="InstallFinalize" />      <Custom Action="ExecAddHostEntry" After="ExecInstallService" >NOT Installed AND NOT REMOVE</Custom>      <Custom Action="ExecRemoveService" After="ExecInstallService" >(NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")</Custom>      <Custom Action="ExecDeleteFiles" After="ExecRemoveService" >(NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")</Custom>    </InstallExecuteSequence>

<CustomAction Id='ExecRemoveService' Directory="INSTALLDIR" Execute="deferred" ExeCommand='cmd.exe /k "My.exe -remove & exit"' Return="check" Impersonate="no"></CustomAction>


But when there is no folder and I am getting error when removing. Is there is way to ignore if no folder exist,


Product: My Service -- Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: ExecInstallService, location: C:\Location\, command: cmd.exe /k "My.exe -remove & My.exe -install & exit"
