Could this be the issue?</P><P></P><P>Can anyone shed some light, please?</P></BODY></HTML> Mon, 26 Jan 2026 16:26:21 GMT https://community.qlik.com/t5/QlikView/Deploy-App-with-OCX/m-p/252650#M1236258 2026-01-26T16:26:21Z Deploy App with OCX https://community.qlik.com/t5/QlikView/Deploy-App-with-OCX/m-p/252651#M1236261 <HTML><HEAD></HEAD><BODY><P>this could be the issue. there is a seperate ocx for qv64, but on my last research the qv10 64bit installer, installed a non working ocx 9.0 component.</P></BODY></HTML> Tue, 28 Jun 2011 17:41:46 GMT https://community.qlik.com/t5/QlikView/Deploy-App-with-OCX/m-p/252651#M1236261 konrad_mattheis 2011-06-28T17:41:46Z Deploy App with OCX https://community.qlik.com/t5/QlikView/Deploy-App-with-OCX/m-p/252652#M1236265 <HTML><HEAD></HEAD><BODY><P>The QlikOCX component is a 32 bits software. If you are not targeting a specific platform (x86 or x64), a x64 machine will execute your application in a 64 bits process and will try to load the x64 version of your component. Target x86 instead to force the application to use the 32 bits component.</P></BODY></HTML> Wed, 29 Jun 2011 08:15:07 GMT https://community.qlik.com/t5/QlikView/Deploy-App-with-OCX/m-p/252652#M1236265 2011-06-29T08:15:07Z
