I cannot uninstall WSUS 3.0 64bit and getting many failure messages. The first error that I got was using Add/Remove programs removed that told me a failure to complete the un-install, but removed it from the Add/Remove Programs list! After that when I used the command-line /u parameter then it also failed every time. Below are the four error lines that always occurred:
2007-06-19 16:50:08 Error MWUSSetup RemoveWsus: MWUS Uninstall Failed (Error 0x80070645: This action is only valid for products that are currently installed.)
2007-06-19 16:50:08 Error MWUSSetup Wsus MSI uninstallation failed. (Error 0x80070645: This action is only valid for products that are currently installed.)
2007-06-19 16:50:08 Error MWUSSetup CSetupDriver::LaunchSetup:

2007-06-19 16:50:09 Error MWUSSetup DoInstall: Wsus setup failed (Error 0x80070645: This action is only valid for products that are currently installed.)
Is there any solution for this failure messages? Thanks
