Maintenance Tool reports corrupted installation
I have Qt 5.4 on Windows 7(sp1), which was updated from an earlier installation of Qt5.0.
When I start MaintenanceTool.exe I get an error dialog saying:
Your installation seems to be corrupted. Please consider re-installing from scratch.
When I hit ok the maintenance tool opens up and appears to work correctly.
Qt Creator starts and seems to be working as well.
Just wondering if there is a repair tool to fix whatever is wrong, or log files I can inspect to see if this is fixable, or should I follow the suggestion given and re-install?
Here's what I have found so far...

It looks like nobody here knows how to answer your question. I suggest asking at the Interest mailing list (you need to subscribe first), to reach the Qt engineers.
Hi, I've encountered the same problem. I'm also running Qt on Windows 7(sp1) professional.
As described above: when I start MaintenanceTool.exe I get an error dialog saying:
"Your installation seems to be corrupted. Please consider re-installing from scratch."
A few days later, the MaintenanceTool.exe would not start at all. So I can not uninstall Qt. . .
The following solution will let you start MaintenanceTool.exe and let you uninstall Qt.
Go to your Qt Folder on C:/Qt
See if you can find a file called "MaintenanceTool.dat"
-> In my case, I could not find it, and it appeared to be named as "MaintenanceTool.dat.New".
Rename the "MaintenanceTool.dat.New" file to -> "MaintenanceTool.dat"
Try relaunching MaintenanceTool.exe (It should start now)
Select the "Uninstall Only" box, then press "Next", then press "Uninstall".
If you need, Re-install Qt by downloading a fresh version from the Qt website.
Hope this helps. Nick D.
