Hi folks, I got a problem with slipstreaming Windows Media Player 11 with WMP11 Slipstreamer v0.991. A screen pops up and It is said: "An unhandled exception has occurred in the worker thread. Please copy the following diagnostic information and post a bug report." The next information is also included: Hotfixes: kb928788.exe kb929399.exe kb929773.exe kb932390.exe kb933547.exe kb935551.exe kb935552.exe kb939209.exe kb939683.exe kb942264.exe kb944110.exe kb944882.exe kb946665.exe System.ComponentModel.Win32Exception: %1 is not a valid Win32 application at Epsilon.Win32.Resources.ResourceEditor.throwWin32Exception() at Epsilon.Win32.Resources.ResourceEditor.loadResourceLibrary() at WMP11Slipstreamer.CM.GetCabData(String pathToSfxCab) at WMP11Slipstreamer.Backend.NativeExtractHotfix(String hotfixInstaller, String destinationPath) at WMP11Slipstreamer.Backend.standardHotfixApply(String fixesFolder, Dictionary`2 hotfixFileDictionary) at WMP11Slipstreamer.Backend.ApplyFixes() at WMP11Slipstreamer.MainGUI.workerMethod(Object addonSettings) Deleting "C:\Documents and Settings\Ardi\Desktop\Windows XP Unattended\i386\wmp11temp"... Done! The source being modified has not been damaged. All changes have been successfully reverted. As you can see I renamed the Windows Mediaplayer hotfixes. How could I succesfully integrate Windows Media Player 11 and it's hotfixes with the original Windows XP source cd? Sorry for my bad english Thanks in Advance
