I attempted to install Ontime but it relies on a 32 bit dll to run.
If you just want to host some bug tracking software then I don't suppose it matters if you use 32 or 64 OS. Though, frankly I would look to someone else to host and maintain that kind of stuff so you can concentrate on development. I also never install that on a production server that is hosting your site.
Thank you, I will do the php install on my current x64 server and not worry about 32 bit dlls until the time comes up again.
