Yay! My first post on this forum! Anyway, I had this problem before. You could really easy resolve this with LockHunter! Just go to http://lockhunter.com/ and download it. Then after installing it, make a fresh installation of MCP and put the Forge source in it. When that's done, you go to the main folder where your mcp installation is, meaning that if I installed MCP in c:\mcp72\ for example, you'll have to go to c:\ in your explorer. Then right-click on your mcp folder. There will be an option there called "What is locking this folder?". Click that and a GUI will popup. In the GUI you'll click unlock and close the program. Forge should install correctly now. It's a completely other solution than SanAndreasP gave here, but by far the best one. Why? Because it unlocks the folder from explorer.exe. The reason why you get this error, is because the folder is opened in the memory of explorer.exe. LockHunter simply unloads it. Don't worry, you can still go to the forge folder with explorer to click on install.cmd. LockHunter is also a really nice utility for deleting/renaming files when they don't want to. Do exactly the same, and you'll be able to delete/rename what you want deleted/renaming. There are even options to do this directly in the program.
