Hello Ladies and Gents,

We have received Qt 4 and will test it out. We have Qt 3 installed now and wonder if it is possible to install Qt 4 simultaneously with Qt 3 or if Qt 3 must first be removed? Will these two bump their heads with identical file names and such? I'd like to test my application changes in both worlds before saying adieu to Qt 3.

Cheers,
Math

You can install Qt4 without removing Qt3. They are completely independent and won't interfere each other.

Hello and cheers for the answer.

I apologize for not mentioning this sooner, but I wonder, given that we use MS Visual Studio 2003, will the integration of Qt4 interefere with Qt3? This, I suppose, is the real question I face. Based on the first link you provided, there cannot exist integration with both 3 and 4. Do you agree with this? If they are completely independent it would seem integration of both would be allowable.

Cheers,
Math
