How to unlock a project

I have an old project that I loaded up again today. I forgot that some
components on the form requires license files. As a result, after I open the
project, the project is read only (locked by VB, not by the file system).

Now I have found an older version of license file which is not compatible
with the newer controls. I want to simply remove the newer versions of the
control from the form, and replace them with an older version. However,
since the project is read only, I am unable to do that.

Any idea?

Thanks in advance

find the file you want to unlock, highlight it and right click,select submenu "properties", change the choices of "ReadOnly" into "SavedDocument", all will be ok, good luck.
