VirtualCenter Users Cannot Access Client Log File (1469)
To resolve this problem, allow users access to this directory while they use the VirtualCenter client.
In VirtualCenter 1.2 the location of the client log is changed. Instead of the file being in the VirtualCenter installation directory, the file is stored in either the Temp or TMP directory of the current user. For example C:\Documents and Settings\user_name\Local Settings\Temp\. If that directory is not found then it will be in C:\Temp\.
