I was in the installation of the VMware VirtualBox This problem, the Internet Baidu to find this is a WIN8 system installed on the program will be encountered.
The reason for this problem is due to permissions problems, the solution is as follows:
1,ctrl+shift+esc pull up Task Manager; Note that this is done with Ctrl+shift+esc, not in other ways, and whether the specific other way is effective without experimentation.
2, find the resource manager in the process, right-click the resource Manager, end the process; Note that when you do this you will see that your interface is gone, don't panic, and don't turn off the task Manager.
3, the Explorer has a file button in the upper right corner, single machine, click to run a new task;
4, this step is the key: Enter Explorer.exe in the pop-out box and tick create this task with system administrative privileges, click OK;
I finished the above steps after the installation of the program first time or although there is no 2503 problem again, but the final installation or failure, I executed again the installation program to succeed.
