EasyXLS version 8.4 comes with a 64bit installer that includes 64bit DLLs for .NET.

The release is meant to help our clients who have 64bit applications only, or who want to avoid the DLL hell of mixing 32bit and 64bit in a single application.

Another advantage is that the speed of execution is improved given the fact that the emulation is avoided.

A trial version can be found here.
The customers who purchased the 8.4 version or own the 8.4 version on subscription base can find the 64bit installer under Purchase Items section.
