Compatibility between 32bit QV desktop and 64bit QV Server

Mon, 26 Jan 2026 18:19:17 GMT

Hi,

We are developing QV documents on our 32 bit desktops (connecting to Oracle using the 32 bit drivers). Our QV server is 64 bit and running v9.

1) Will we experience any issues when we deploy these to run on our QV Server?

2) Do we have to install the 64bit Oracle drivers on the server or will 32 bit drivers run ok?

Thanks.

Hello,

I exactly did the same thing this week in my current project. We had to move the server and QV both from 32 Bit to 64 Bit and I did not had any issues at all, even with the Drivers.. I think there will be an issue if you started with 64 Bit and trying to move on to 32 but other wise its just fine and I am happy to say this.. Please try it and let us all know if there are any issues.

On #1, I believe the isnull() function behaves differently in 64 bit QlikView. I always use the len() function instead. If len(MyField)=0, then the field is null. That's all I'm thinking of. We develop on 32 bit machines and publish on a 64 bit server, and have had no problems. We don't use Oracle, though.
