title: Unable to load DLL “OraOps10.dll”
body: <p>I am running into peculiar issue. I am developing a windows based application which connects to Oracle database.</p>
  
  <p>For initial testings, I have created installer and tested on different machines that I have. Each machine has Oracle Client installed and I did not see any problem in running application.</p>
  
  <p>But when I share this installer with customer, he is getting error "Unable to load DLL OraOps10.dll". When asked he mentioned and has shown the Oracle Client installed on his machine and he is able to run other C# applications which connects to Oracle databases.</p>
  
  <p>I do not understand why my application only getting above error. I even tried suggestions shared at <a href="https://forums.oracle.com/forums/thread.jspa?threadID=67364" rel="noreferrer">https://forums.oracle.com/forums/thread.jspa?threadID=67364</a> but still no luck.</p>
  
  <p>I even tried copying executables &amp; DLLs manually on customer's machine. But still facing same issue.</p>
  
  <p>So please help me on what else i can do.</p>
  
  <p>Thanks &amp; Best Regards<br>

  <p>P.S:</p>
  
  <p>I am using Windows XP operating system and customer is also using same operating system. Both machines are of type 32 bit OS only.</p>
  
  <p>This is the location where customer's oracle client installed:
  C:\oracle\product\10.2.0\client_1\bin and same is the version in my case too.</p>
  
  <p>We both are using Oracle 10g.</p>
