Porting LAPI DLLs to 64 bit

We have been trying to make a LAPI code work on a 64 bit Windows system using the following list of LAPI dll's which i believe is written for 32 bit. The LAPI code is not working at all.

 

LAPI_ATTRIBUTES.dll
LAPI_BASE.dll
LAPI_DOCUMENTS.dll
LAPI_INBOX.dll
LAPI_NETp.dll
LAPI_SEARCH.dll
LAPI_SSPIp.dll
LAPI_USERS.dll
LAPI_WORKFLOW.dll
LLKERNEL.dll
llresources.dll

 

Inspecting these dll's in the program Dependency Walker gets me the following message:
----------------------------------
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.

 

Error: Modules with different CPU types were found.

 

Warning: At least one delay-load dependency module was not found.

 

Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
----------------------------------

 

Any idea what could be causing the trouble? Are there 64 bit versions of these DLLs which I could re use? Thanks in advance for any pointers!

LAPI cannot be used in a 64-bit process. The DLLs can be loaded only to a 32-bit process. You can devise you solution with this on your mind. The coexistence of 32-bit and 64-bit components is described generally in the MSDN.

If you cannot build your application as 32-bit (which would be the easiest way), have a look at the thread https://knowledge.opentext.com/go/17261369 which discussed the possibilities what to do with LAPI on 64-bits.
