My Nitro Pro PDF 5 will not install on my new computer

[Jeffrey Weiner 0]

I just installed a new computer running Windows 10 64 bit. My old computer had the same operating system and I was able to use my Nitro PDF Professional ver 5 on it without any problems. This version does everything I need it to do and I don't need all the bells and whistles in the newer versions. The problem arises during installation. I get a message that it is 32 bit and it won't run on a 64 bit machine. Is there a work around for this? It ran fine on the 64 bit system I had previously.
