Is there Install Manager for 64 bit PC?

in New Users
Downloaded Install manager and didn't notice it was 32 bit until after install. Is there a 64 bit version and where to get it. Thanks.

It doesn't need a 64 bit version since it doesn't handle large amounts of data in memory at once. The 32 bit version will run on a 64 bit OS.
Thanks Mr. Haseltine, just wanted to make sure before letting The Manager download and install my stuff. Have a great weekend.
