Qt 5.3.1 install failure Win7-64 (Closing due to 5.3.2 release)
Error during installation process (qt.win32_mingw482):
Qt patch error: Can not open C:/Qt/5.3/mingw482_32/bin/qmake.exe
(The process cannot access the file because it is being used by another process.)
when installing Windows or Android on a Win7-64 machone
Tried both online and downloaded Zip methods.
Hi and welcome to devnet,
Are you using an Antivirus ? IIRC, some of them can interfere
No, not on this machine. (It is isolated from internet)
I can install the software no problems on a Win7 32 bit laptop without issue.
5.2 installed previously without issues. I also uninstalled that prior
to the first attempt.
Any other suggestions?
Did you restart windows in between ? Do you have Qt Creator running ?
Yes, I restarted windows. I have tried ignore and was able to compile program an example program but now get an error about could not find or load the Qt platform plugin "windows". I assume it did not create or copy the qwindows.dll
I will try to locate this file on Monday on a laptop that Qt5.3.1 did install correctly.
One thing is really not clear: are you getting that error running your program from Qt Creator or launching it by e.g. a double click on it ?
Then you probably have not a complete install, you should retry the installation. Ensure that you are starting from a fresh Windows start where you don't have any Qt SDK related software running
Installed 5.3.2 OK
No resolution for 5.3.1 but not needed now.
