LoadLibrary failed with error 183 while loading crypto dll from another C++ program

[RituP]

We are facing some issue with crypto dll and would really appreciate if we
could get any help on this. We are using cryptopp version 5.6.1.0.

We have 2 separate java programs, both use the system.load()function to load
a Cryptowrapper dll (it’s a CPP program which acts as a JNI -Java Native
Interface). This Cryptowrapper inturn calls encrypt/decrypt functions in
Crypto.dll.

For one of the Java program it works without any issue. The password gets
encrypted properly.

But the other Java program when it invokes the JNI Cryptowrapper dll which
further tries to load the crypto.dll. The crypto.dll loading fails; did a
GetLastError()and got the system error code as 183.

myCrypto = LoadLibrary (cryptoPath);

here cryptoPath points to the full path to crypto.dll (including the crypto
dll).

Tried using both Loadlibrary() and LoadlibraryEx(), still it didn’t work.

myCrypto =LoadLibraryEx(cryptoPath, NULL, LOAD_IGNORE_CODE_AUTHZ_LEVEL);

What is confusing is - the same JNI being refered by two Java program in
similar way - in one case the JNI successfully loads the crypto dll while in
another case it gives err 183.

Details about environment – Win XP/ MS Visual studio 2010 runtime
environment.

This issue is Not recreated on all the test machines. However, on multiple
machines where it does gets recreated, I am able to replicate it
consistently.

Thanks in advance..
