Before I uninstalled Qt, I forgot to delete the Qt version in qtvsaddin. As a result, there is an invalid Qt version in qtvsaddin. If I don't reinstall Qt, what should I do? Thanks.
VS add-in (aka Qt Visual Studio Tools) is independent of installed Qt versions, in the sense that the list is maintain separately. You can add and remove versions as you want (even duplicated with different names). When you remove a version in VS it should be removed from both the list view and the combo box, so if it was kept there it is probably due to a bug in the add-in.
You can check the list of versions in the Registry Editor at HKCU\Software\Digia\Versions. You'll see there a key for each version as well as a value with the default one.
Close all instances of Visual Studio. Then remove your version from there and check that there is no value containing such version in HKCU\Software\Digia\Versions. Modify at your risk ;) (do a backup of the key before starting).

A bit of a beginner Mac question but I can't see a way to remove older versions of VS Code from my 'Open With ...' menu.
All other apps seem to correctly overwrite themselves so there is only one of them. Like 'Safari'. But VS Code seems to add a version number, sigh.
I want only one entry for VS Code. The latest one.
This is what I'm currently seeing:
I made a laucher application in c++ that use direct 2d and 3d. Now i making a installer for this. I followed microsoft docs and i made it but there is a issue.
I use 'Microsoft Visual Studio Installer Projects' extension to make that.
The issue is if i already installed my launcher with a previous installer msi file, if i rebuilt a new installer msi and try to run it it show me this error
This is the microft docs i followed to make this: https://learn.microsoft.com/en-us/cpp/ide/walkthrough-deploying-your-program-cpp?view=msvc-160
In the future maybe i need make a update for my laucher. It isn't good idea everytime need go to control panel, search and delete the previous application and install the new one manually.
Anyone know how can i make it automatic remove old version and install new one? Maybe there is a better way to create a installer?
Major Upgrade: In order to upgrade properly, you need to use a major upgrade so that your new version uninstalls the old one and then installs itself (this can happen in reverse order too: new version installed and old remnants deleted afterwards, but this is another story). There are further upgrade types, but stick to major upgrades for simplicity.
The message you are receiving is basically because you have a different package code for the new MSI, but not a new product code or version number (or just one of those problems). You need to get the settings straight.
Recommended step-by-step:
Set "RemovePreviousVersions" to True in the project properties.
In the same place: bump up your version number (one of the first 3 digits)
Answer yes when asked to change product code, or do so yourself manually.
Keep the UpgradeCode the same - it needs to be stable across releases.
Rebuild your setups. Clean out your box of old remnants before testing or test on a virtual.
Testing: Remember to simulate your full upgrade process from first version installed to the new one with different version numbers for a few core files and also try to add a few files and such things. Very important to verify.
Heads-Up: Before ending, it is standard procedure to warn about the potential limitations of VSInstaller Projects (shorter list form).

I am a Total Noob at this and I know nearly nothing about this.
I just started using Qt Creator for windows 5.6.0 and While I wrote my first "Hello World" code..
I was asked to add a kit. I searched the net for similar issues and it said that I needed a compiler for Qt. Thus, I installed MinGW from QtForums
now when go to Tools->Options->Build&Run->compiler, I can not understand how do I add it to the list.
Please help me through it?
To just get started the easiest thing to do would be to go here:
Link to Qt downloads page
Scroll down and select Qt 5.6.0 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) this will download the installer (its about 1 GB). Run it and choose all the default options. Then you will have Qt 5.6 with mingw and Qt Creator all setup ready to go.
Note: Before you start that its probably best to delete your current version - if you are not attached to it in any way :)
If you want to fix your current setup, then it might be longer-winded to find out what you are missing for mingw. For example you need the mingw qmake file that would be located here (using default install options):
C:\Qt\Qt5.5.1\5.5\mingw492_32\bin\qmake.exe
to create your "Qt Version" part of the kit. And the actual mingw compiler, which is located here (using default install options):
C:\Qt\Qt5.5.1\Tools\mingw492_32\bin\g++.exe
to create your compiler. Once you have both of these then you can put them together to create your new kit.
But to just add a compiler all you need to do is:
Click compilers tab
Click add and select mingw
A new compiler is added, click it
You will see some options below, add your compiler executable path in (like the one above for example).
And you are done - there are some other options, but you probably don't need to use them.
note my paths are for qt 5.5.1 (obviously) so slightly different to 5.6 :)
update
Its all been moved around! - here are the new paths:
offline-installers
old-version-archives
Well. I was unable to provide the data before but it all makes more sense now.
What I had installed was Qt for windows 64-bit (vs 2013, 836mb).
Hence, Instead of MinGW, I have msvc2013_64. It does have qmake.exe but doesnt have g++.exe. And I had downloaded it separately.
You're answer was very helpful.
Added MinGW packages to QT installation with the QT Maintenance Tool (C:\Qt\MaintenanceTool.exe)
It allows to add/remove components via the qt repositories. So no need for re-installation.
This question actually is an implicit answer, since I could fix the problem in the meantime for myself. But I wanted to publish my experience, since some other developers might have a similar problems.
The problem:
I am using VS2010 prof SP1 on Windows XP SP3, pure C++ only. (AntiVirus software present).
Since some days Intellisense - which is quite helpful under normal conditions - does not work anymore.
Things tried:
created a new simple console application. -> Intellisense still not working.
resetting VS-Settings by means of Tools/Import & Export Settings/Reset. -> Intellisense still not working
Changes to option settings in Text-Editor/C++/Advanced inclusive logging did not help.
-> Intellisense still not working
There was actually an interesting observation:
Intellisense normally creates a directory 'ipch' in the solution directory to store intermediate files. In my solution folders it disappeared as soon as the solution was opened. When I created a folder 'ipch' and opened the solution Intellisense removed the folder again - strange.
The final fix:
During the last week some new Windows updates were installed. I noticed some other unusual behaviour of my PC as well. After having created an image of my PC, I decided to
uninstall Windows updates from 2013-09-11 (4 packages) and one update from 2013-08-28.
(unfortunately I did not note down the KB-numbers)
AND: out of a sudden Intellisense is working again !
Maybe this report could be helpful for some other persons.
Automatic Updates are now disabled on my PCs.
Confirmed 100%
Microsoft Visual Studio 2010 Version 10.0.30319.1 RTMRel
Microsoft NET framework 4.0.30319 RTMRel
Microsoft Windows XP Professional Version 2002 Service Pack 3
Intellisense stops working after installing KB2876217.
Intellisense is back after removing update.
I had the same problem and also had the idea that one of the Windows Updates is buggy, so I can confirm your report.
I tried to uninstall them one-b<-one and found the "bad guy":
KB2876217 destroys intellisense for VS2010 under XP SP3.
A supported hotfix is available from Microsoft to fix this issue. Check at http://support.microsoft.com/kb/2526044/en-us
Actually, it may not be such a good idea to uninstall update KB2876217. Instead, install Visual Studio SP1 update (if not already installed) and then install update KB2526044. I have tried it before and it does work...
I want to use qt creator, only as an editor, which does code completion and finds declarations etc. I dont want to use it to build etc. Is there a way, I can circumvent the need of qt-libraries? I am using a server, where my file space is limited. Also, without qt libraries, it does not allow making even a project. When I tried to install qt-libraries, it configures fine, but on make gives error.
So, can you suggest an alternative? Thanks
No, you need the Qt libs because the editor was coded in Qt.
Actually - at least under Windows -, you can. You just have to deselect all Qt library versions and only select the editor. If you want to have a debugger available on Windows, also select the checkbox for CDB support.
I have forgotten how this works with the Linux installer, but I imagine the same applies there as well, except of course for the CDB debugger, which is not available on Linux. Instead you should be able to chose from GDB and some other alternatives, though it might not be during the installation.
Once you installed it and are about to set up a new "Plain C++" project, you can't select a Qt version when creating a new kit, obviously.
If you blindly selected an already existing kit, Qt Creator might have tried to use a Qt installation for your vanilla C++ project. Instead of doing so, you should click the "Manage..." button on one of your preexisting kits and add a new, custom kit. Here you can set the "Qt version" option to "None". The rest should be set according to your needs.
