Q: Itunes No Longer Opens On Windows PC

For many days Itunes has not opened. Nothing happens, no error messages come up or anything, it just doesn't do anything. I have uninstalled and reinstalled several times, even tried an older version of it and nothing has worked. I tried to run it in safemode and it still didn't work. Everything else on my computer works fine, only Itunes wont work. I have emailed customer support many times and they wont help or give me any hints of what to do.
