Plus, never use DSNs, always use a DSNless connection.

It's possible the Tally driver you're using is 32-bit only. Recompile your .DLL to target x86 instead of x64 or AnyCPU and give that a try.

tried recompiling with x86 and registered under .netframwork but gave error so tried registering under .netframework64 still error

tried running tally in 64 bit and 32 bit still error comes
my operating system is 64bit

I have no idea what you're talking about what you say "registered under ..."

Running Tally "in 64 bit and 32 bit" means nothing.

If you are referencing or otherwise using any Tally .dll's in your .dll, your architecture (x86 for 32-bit or x64 for 64-bit) MUST match the architecture of the .dll's you're using.

If they don't match, it won't work.

Registering my x86 or 32 bit dll in. Netframework64 gives error saying drivers not found for tally odbc. Tally odbc server is automatically installed when tally is opened. I m using tally odbc 32bit
