@Davronito Yes many times.........

@SGaist said: id you also nuke the build folder ? Did you move your project in a different path ? Did you rename the path/folder containing it ? I've done the first. Then I just copied my project folder from my pc and opened project on usb drive - it worked. But starting from scratch (deleting every qt-creator related file, like .user) didn't help. So i just moved directory completely and it worked. It's still very strange because Git didn't any changes in project files so only hidden by gitignore remains and I'm pretty sure I tried to delete them.

HI, if you use MSVC and not mingw you must replace the line C: \ Qt \ Qt5.4.0 \ Tools \ mingw482_32 \ bin \ mingw32-make.exe by nmake (cf Qt documentation) and I believe it's not recommended to use Qt 5.4.0 and MSVC,it's better tou use Qt 5.4.1 (binary compatiblity problems with 5.4.0 and MSVC)
