Is the file/directory in use when the delete was attempted? Is there a reason you have to delete the file instead of just overwriting it? Have you pondered using a RemoveFile element to explicitly remove the files you are creating in your CA on uninstall?

Subject: [WiX-users] Custom action "System.IO.DirectoryNotFoundException" on second Installation I have been making a Wix Installer that is supposed to install the contents and fetches the parameters passed in terminal and create files. ie. msiexec /i installer.msi /l*v out.log IPADDRESS="1.1.1.1" will create a file lpa.config. I have following wix file and custom action file. WIX: <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi";> <Product Id="*" Name="CustomWixInstallerWithCustomAction" Language="1033" Version="1.0.0.0" Manufacturer="LogPoint" UpgradeCode="ba9015b9-027f-4451-adb2-e38f9168a850"> <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" /> <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." /> <MediaTemplate EmbedCab="yes" /> <Feature Id="ProductFeature" Title="CustomWixInstallerWithCustomAction" Level="1"> <ComponentGroupRef Id="ProductComponents" /> </Feature> </Product> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="WindowsVolume"> <Directory Id="INSTALLFOLDER" Name="lpaa" /> </Directory> </Directory> </Fragment> <Fragment> <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER"> <Component Id="SomeRandomEXE"> <File Source ="G:\SarVaGYa\myworkspace\LatestLpa\lpa\lpa_c\build_win\src\lpa\Release\lpa.exe" /> </Component> </ComponentGroup> <Binary Id="SetupCA" SourceFile="G:\visual studio stuffs\SetupCA\SetupCA\bin\Release\SetupCA.CA.dll"/> <CustomAction Id="WRITEFILETODISK" Execute="immediate" BinaryKey="SetupCA" DllEntry="WriteFileToDisk" /> <InstallExecuteSequence> <Custom Action="WRITEFILETODISK" Sequence="2">NOT Installed AND NOT PATCH</Custom> </InstallExecuteSequence> </Fragment> </Wix> and the Custom Action File namespace SetupCA { public class CustomActions { [CustomAction] public static ActionResult WriteFileToDisk(Session session) { session.Log("Entering WriteFileToDisk"); string ipAddress = session["IPADDRESS"]; string productCode = session["ProductCode"]; string ssl = session["SSL"]; string compression = session["COMP"]; string config_path = "C:\\lpaa\\"; string temp = @" {{ ""logpoint_ip"" : ""{0}"", ""ssl"" : ""{1}"", ""compression"" : ""{2}"" }}"; if (string.IsNullOrEmpty(ssl)) { ssl = "False"; } if (string.IsNullOrEmpty(compression)) { compression = "True"; } string config = string.Format(temp, ipAddress,ssl,compression); session.Log("Config Generated from property is: " + config); try { System.IO.Directory.Delete(config_path, true); //Recursive delete content inside LogPointAgent Folder } catch (Exception e) { session.Log("LogPointAgent Directory Deletion Unsuccessful. Exception: " + e.ToString()); } try { System.IO.Directory.CreateDirectory(config_path); } catch (Exception e) { session.Log("LogPointAgent Directory Creation Unsuccessful.

Exception: " + e.ToString()); } session.Log("Confile file is written"); session.Log("Product Code file is written"); return ActionResult.Success; } } } The installer works fine when it is freshly installed but if I uninstall it, it will have residues productcode.txt and lpa.config as it was not installed by installer. If after uninstalling and installing it again, it doesn't create these files. If looked in the out.log file, it will get exception: Config File Writing Unsuccessful.
