I’ve been struggling trying to upgrade my WinXP image after installing Parallels for on my MacBookPro. Every time I go to install Parallel tools, it just hangs after a while. Problem is that Windows thinks the underlying hardware has changed significantly so it is asking to re-activate the software.
At first, I didn’t have mouse access so I tried once again to install Parallel Tools; it hung again this time but after Force Quitting it, I had mouse and network access. Next I started the VM again and activated Windows. After that completed successfully, I was able to install Parallel Tools.
