problem to run program on Windows 7

Hi.
I have problem with running my application on clean windows 7.

I compile my application on Windows 7 with Qt 4.7.4 MinGW 4.4. On this installation everything works fine but on clean(windows) installation i got this error message. I copy dll`s from mingw forlder (C:\QtSDK\Desktop\Qt\4.7.4\mingw\bin).

Could you help me with this problem?
I have no ideas what is wrong.
I compile this program on debian also and it works.

Have you *installed* your program? Or built it from source? If you have just copied it then ... you are missing dlls.


On you clean install, have your properly installed Qt? do examples work?
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

I build my program on one machine and copy to other (both with windows 7, copy also dll`s).
In other machine i have no Qt(libraries or SDK) installed.

I check depences with "depency walker" and find no difference.

Maybe i missed some library but how can i check this?

Sorry, you cannot just copy over binaries and expect it to work. You need a proper installation.

It could be you have no, or a mismatch of a c++ redistributable.

you can't. That's why installers exist.

I wan`t to build application to run from pendrive(no install it everytime).

Maybe i can build with static library and then run on other systems?

ms Visual Studio tells me that I need to include:
Microsoft_VC80_DebugCRT_x86.msm
policy_8_0_microsoft_vc80_debugcrt_x86.msm
(as well as some Qt dlls)

for a very simple win32 qt app.

yes - you have to rebuild Qt so that it's built as libs not dlls

how to build 'static' apps is easy - building static qt libs will need a google. sorry.
