Installing Hardware Updates

[PLCMania 0]

Hi, I have SIMATIC Manager V5.2. I want to update the Hardware Catalog in order to add a new module from SIEMENS. The module part No. doesn't contain in HW Catalog. I did it using Internet connection and now I have an XML file and many update files. Now I'm trying to update another computer using this file, but it happens nothing and the updates don't appear in the window. I tried also using the internet again on both computers, but the message "can not create target file" appeares. I used the command "Option\Install HW Updates.." in Hardware configuration package. I also tried the file "HSP2005_11.exe" from Siemens support center, but it happens nothing. Any Idea?
