I get a yellow warning triangle with an exclamation mark in it when the installation manager is about half way through installing and when it reached 100% and I check my programs it isn't installed.  Is there a way to fix this? I purchased this online and am installing from the download version of Movie Edit Pro 17 Plus. I'm trying to install on Windows 7 sp1, 64-bit, Intel Core i7 with 4 GB of RAM. Any suggestions would be helpful.
