Well Keepass have two different versions, one of 32 bits and other of 64 bits.If u install the 64 bit version does not unistall the 32 bit version.
I don't think this is true. There are no separate installers for 32 bit vs 64 bit. Keepass 2.x uses a single installer and runs as either 32 bit or 64 bit depending on the OS it's installed on.
There is the older 1.x version, but it's only 32 bit.
There is no conflict between these two versions though, because they used different file formats.
There's also an installed versus a portable version. The installed version uses either an EXE or MSI installer, while the portable version is just copied to a folder from a zip archive.
Installing a new installed version will replace an existing one. If you're using the portable version there is no uninstaller, you just have to delete the files.
