I have two machines, 32 and 64 bit. Downloaded the exe and it installs fine on the 32 bit machine but on the 64 bit the installation hangs up at the entry of the SN and product key. The dialog appears that says the product key may be correct..... and I click OK. The installation just spins at that point and won't go any further. You can't cancel or proceed and the only way to exit the installation is through the task manager.

I've tried restarting but no improvement. Any suggestions? All entries have been correct so that is not the issue.
