Switching from 32 to 64 bit

[Kundan]

I have changed my OS from Windows 7 (32 bit) to Windows 10 (64 bit). When I run my Access 2013 (32 bit ) databases on this 64 bit OS I get errors like "32 bit encryption", Macros cannot run, etc. How to solve these problems?

The Windows bitness doesn't matter. The important thing is whether you have also changed from 32-bit to 64-bit Office. If the latter then there will be changes to make if you use API declarations.
Also ACCDE files created in 32-bit Access won't run in 64-bit Access (and vice versa).

NOTE : You can install 32-bit Office in 64-bit Windows

Also, it would be helpful to post a screenshot of the exact error message
