How to get QT Creator version 4.8.1
I want to install QT Creator version 4.8.1 on a Windows machine. This seems like it should be easy but it is very confusing. I was able to download and install QT version 5 which included the QT creator without problems. But for version 4.8.1... I downloaded and installed the file " qt-win-opensource-4.8.1-mingw.exe". This installed QT designer but not QT Creator. I would like to edit in QT creator (not VS2008 or VS2010). What must I download and install to get QT Creator version 4.8.1? Where can I find this installer?
Hi and welcome to devnet,
the Qt used to build QtCreator has no influence on the one you want to use to develop. Just install the latest version of QtCreator and configure it to use your Qt 4.8 (by the way why not the latest ?)
Hi and thanks for the info. I'll give it a try tonight. I want QT 4.8.1 because I need to modify a program written in QT4.8.1. I'll let you know if I get the QT Creator with 4.8.1 installed so I can edit/compile the code. Thanks again!

Qt is forward and backward compatible (source and binary compatibility) for every major version. You can safely compile your project using latest version of Qt.
That's generally true but false in practice. I've run into many situations where an older project will not compile due to things being removed or changed around between Qt versions until it has been updated.
No big deal. Most often the changes are very minor, involving just a few lines, which is great. But for those who are just learning or are not familiar with the changes it can take time and a bit of wading into deeper waters to resolve. This is more true in some areas than others, of course.
Sure, the techniques for getting a project to compile across many versions are documented, but many older projects don't include them and they are by no means universally adopted.
If the older project was built against Qt 3 and then you try with Qt 4, indeed it might need some porting to do. Qt guaranties binary/api compatibility within a major release but it might break between two major releases (3 to 4, 4 to 5).
But typically in this case here, building your application with 4.8.5 and run it using 4.8.1 won't be a problem.
I am having some issue regarding 64 bit versions.
I have python 2.7.4 64 bit and want to use Pyqt4 and Qt creator. Before that, I have to install SIP, which is proving to be a pain as there does not seem to be much in the way of a clear instruction on how to find a 64 bit version, much less an explanation of the SIP install for a windows 7 64 bit machine. It seems that there are small snippets that somehow relate to it but you have to jump across multiple pages to try and collate information which is sort of what you are looking for.
If anyone can explain this to me, I will be grateful.
Windows 7 64 bit
python 2.7.4 64 bit
Need to install
SIP (64 bit version) The install doc is not very helpful. I do have the download
PyQt4 (64 bit) I do have the download
Qt creator, needed as well as the Qt Designer which is part of the PyQt install.
So that is three things I need to do, but its proving to be a real pain. Most of the answers I get point me to pages I have already visited and not been able to get much from.
Help will be appreciated
