Hi Marcos, i received your PM. When i run Sysinspector manualy it says unable to load "ESET Sysinspector's module". But i think i found the problem. The EEA+AGENT was installed from an administrator level account which have its profile folder encrypted (EFS). I reinstall EEA+AGENT from another account that has unencrypted profile folder.
Now the blank window is gone and Sysinspector works too. I'm writing it in here so others may benefit from it, although i dont think many users, even in corporate environment, use EFS
Thanks for your help.
