Installation tips: 1. If there is a similar prompt such as pips is not upgrade, it means that these things have been solidified in the firmware of your phone. Just press OK all the way.

2. If there is an SWI error 0 !:sys bin and other error+ digits, leave it alone, but don't turn it off either. If it is turned off, QT will stop the installation.

After the installation is completed, you will find that qt and database have been successfully installed.

The cross-platform of qt refers to "write once and compile everywhere", which means that the ** you write generally does not need to do special processing to compile with qt on different platforms.

For the problem you mentioned, the program you compile under the win7 64-bit system depends on whether you compile and generate a 32-bit program or a 64-bit program. If it is a 32-bit program, then it is no problem to run on both 32-bit and 64-bit Windows systems; If it is a 64-bit program, it can only be run on a 64-bit Windows system.

If your program does not have any special requirements on the configuration, of course, you don't need the relevant configuration, just copy the corresponding dll file to your program running directory, you can go to the Internet to search for the release of the qt program.

42CrMo4 is an industrial material. 42CrMo4 is used to manufacture forgings that require higher strength and larger quenching and tempering cross-section than 35CrMo steel, such as large gears for internal locomotive traction, capacitive pressure transmission gears, rear axles, connecting rods and spring clamps with great load, and 42CrMo4 can also be used for oil deep well drill pipe joints and fishing tools below 2000m.

42CRMO steel is an ultra-high strength steel, with high strength and toughness, good hardenability, no obvious tempering brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low-temperature impact toughness. The steel is suitable for manufacturing large and medium-sized plastic molds that require a certain strength and toughness.

QT: Quenching (air or liquid) + tempering (air cooling or liquid cooling) + tempering. That is, the meaning of heat treatment.

Maybe you've installed it before, but you haven't uninstalled it cleanly, you can try it under the independent installer:

client profile

win8？Take a look at the Control Panel->Programs & Functions->Turn on or off the Windows function, and see if there is a direct opening in it.

It's not a problem with the system.

Installed in Control Panel -> Programs & Features -> Enable or disable Windows features, which are available as shown below.

Visually it is installed higher than the higher. .net version, but generally speaking, it is backward compatible, and theoretically the software above the environment can also be run, and the uninstallation method has to be uninstalled in the control panel.

Friend, what version you originally installed will pop up after the existing and delete it, and then install the version you want, just reply.

Open the program in the Control Panel, find a later version of .NET or any other version in it, uninstall it, and reinstall .NET Framework 4.
