Description
"An Error occurred while trying to uninstall application. It may have already been uninstalled..." message appears after attempt to uninstall an application from "Programs and Features"(Add/Remove Programs)
The reason is that the value of UninstallString(HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Your Application Name) contains "C:\WINDOWS\system32\javaws.exe" instead of "C:\WINDOWS\SysWOW64\javaws.exe"
Comments
No plans to fix for 6u or 7u. Raise the concern via me or Support if there's an issue

this is even worse in JDK9 - would fail even on a 32 bit os, or with 64 bit java deployment stack installed. The code to create shortcuts we updated to use the full path to javaws.exe from the latest jre installed, instead of using windows system dir/javaws.exe, using RegFX.GetLatestJavaws32or64BitHome(). However the code to create Add/Remove program entries was never updated, so it points uninstall to non-existant c:/windows/system32/javaws.exe. javaws.exe is no longer in the windows system dir, so this change must be applied not only to shortcut creation, but to all other places path to javaws.exe is put in registry: 1.) Java_com_sun_deploy_config_WinPlatform_addRemoveProgramsAdd 2.) Java_com_sun_deploy_config_WinPlatform_addRemoveProgramsRemove looks like everything else was updated by updating Platform.getSystemJavawsPath(), but for shortcuts, updateShortcutToLatestJRE() only updates shortcuts, not AddRemoveProgram entries or Associations.
