Here is the problem I've been having, I installed Quicktime, everything worked fine and I have Quicktime Picture Viewer as my default viewer (I miss my mac). I was able to use it for some time, then when it starts to open the window which asks me to upgrade to Quicktime pro it crashes. I've tried reinstalls and updates but to no avail. Then I reformatted my Hard Drive, and the same issue is happening. Any ideas?
