@fsfarimani no I have not checked each and every package. Also, not every package starting with qt has something to do with that framework. For example qtfaststart is a video related package. If you want more information about the packages provided by brew, you should contact their maintainers. The Qt Project does not handle them.

Hi Try to remove "C:\Users\USERNAME\AppData\Roaming\Qt\qtaccount.ini" (copy it first to somewhere to be able to put it back if it explodes :)

Hi koahning, I've had a similar problem. Maybe my bugreport helps: https://bugreports.qt.io/browse/QTIFW-1003 After installing notepad++ and assigning ".vbs" extension to it, windows wasn't able to execute ".vbs" scripts anymore. Resetting the assignment in the regedit (HKEY_CLASSES_ROOT.vbs to "VBSFile") solves this issue. Maybe this solves your issue, too. Regards Jazzco

Thanks for the input. On WIndows, when you run the Maintenance Tool you check off which compiler you want to use. The Maintenance Tool downloads that compiler. At the point this error happens I have seen the Maintenance Tool download the correct compiler to the Qt directory.

@aha_1980 well its not an easy tool to use. I'm currently fighting with it as well, my antivirus pushes it into quarantine because it may be a potential virus. Only happens with my own created tools not the QtCreator one. I'm still trying to figure that one out...

Glad you found out and thanks for sharing ! Can you also share which antivirus it is ? That might give clue for other people experiencing the same situation.

@Tsherr Hello, I have the same issue, tell me please, did you found solution for this problem?

I stumbled upon this answer and added those links found in this this xml file: http://download.qt-project.org/online/qtsdkrepository/linux_x64/desktop/tools_maintenance http://download.qt-project.org/online/qtsdkrepository/linux_x64/root/qt Now I have repositories configured and everything is fine.

I remember having a problem similar but what I did to avoid losing time is to grab the online installer and get Qt 5.5 directly

Thanks SGaist, I built it on my end and seem to be working alright.

@vlada well if u have a commercial licence that the right thing to do but if you are using open version then skipping should be just fine :)

You can use "UNDOEXECUTE". For example: component.addOperation("Execute", "msiexec", "/i", "xxx.msi", "/quiet", "UNDOEXECUTE", "msiexec", "/x", "xxx.msi");

@JKSH I tried a few things and it seems it's an access violation error. Normally it should crash but I think it is an unhandled try-catch block. Probably I am going to do the same on this machine too that is, Delete Qt folder manually and install 5.5, and hope that this issue is fixed in the new version :)

@sassanh said in Maintenance Tool reports corrupted installation: @Asperamanca How did you edit MaintenanceTool.dat file? It's a binary file containing xml data and some binary characters between tags. When I remove a single character in it running MaintenanceTool shows errors like this: Cannot seek to -15118 to read the operation data. I don't remember exactly. I changed only XML parts, and it worked for me. But that was before the major update to the Maintenance tool that came recently. Maybe they added a CRC check on the file, or something like this.

mcosta, Yes, found it - not too blind but too stupid :) thank you
