After upgrading from ZCM 10 to ZCM 11 I am unable to install the Reporting Server. When I run the Setup the Prerequisite Check prompt that ZENworks 11 Reporting Server Already Installed in Local Machine. This is not correct. Version 10.3.1 is still installed.

After that I tried to run zrsunstall.exe but this program gives the following error: Win64 not supported: The Author of the package you are installing did not include support for this platform.

Operating System is Windows 2008R2.

Does anyone know how to uninstall the 10.3.1 version of the Reporting Server or install version 11.0 without the error as described above.

Thanks in advanced.
