I found out the problem!

The problem is that winrar is unable to create the files on the temp folder.
This is a fresh install of windows 8 and it worked before, but I noticed that more recently execution issues with the temp folder - I believe that M$ had protected the temp folder against execution, the problem is that many installer extract component to that location and execute from there...

My temp folder have all permissions to Administrator, but only read/write for Everyone - this is not enough, winrar requires Modify permissions (that will grant the execute also).

When the permissions fails, the winrar alternative is to extract for the same folder of the opened file, than it make the mistake of coping all the forder to the destination of the drag&drop

My solution was to create a temp folder with the necessary permission just for winrar to use, and configure winrar to use this folder.
For now I will keep the permissions of the default windows temp folder.
