Problem with upgrading the Web-server

Problem with upgrading the Web-server

Hi,
I'm upgrading the web-server version from 6.50 to 6.51.

1- At first we just installing the Web-server version without deleting the previous version. Then we change the zenOn version in the global_vars.js setting and after that Start the Web-server. When we start RT from Web-client, there's an error message shows that they couldn't find the alc.mp file.
2- Then we tried to uninstall the web-server and re-install the program back. But we found out in the folder :\C\Program Files\Copa-Data\zenOn WEB Server,that there's no zenOn folder which consists of global_vars.js and etc.
We try to install the web-server in other machine. The folder is there! I do not know what when wrong. Do you have any clue?
