That turned out not to be such a smart move. Not only did d09 fail to install (stopping 1/2 way through with a 'failed to find setup.msi' error), but it trashed my d07 install as well. I don't know how bad the trashing was, I killed delphi after the 10th "package not found error" on start up.
I am not blaming CodeGear for this, my D07 install was "customised" to fit on a small virtual machine, with several, possibly important, folders deleted, and with little free space remaining.
One of the many nice things about using a virtual machine is the ease of backups and recovery. In this case, it came down to a 2 step process
- Copy fridays backup onto the computer
- Use subversion to retrieve all the files changed since friday
Moral of the story: If you are installing D2009 (or any other version), put it in a virtual machine.
And use version control
And backup regularly
