I run a Qt C++ project in Visual studio and got "the program can not start because QtCored4.dll" is missing

I am running a Qt C++ Project in Visual Studio 2008 and I got this error message:

"The program can't start because QtCored.dll is missing from your computer. Try installing the program to fix this problem".

Then I copy: QtCored4.dll from C:\Qt\4.8.0\bin to the exe program

I run it again, I got:

"The program can't start because QtGuid4.dll is missing from your computer. Try installing the program to fix this problem".

Then I copy: QtGuid4.dll from C:\Qt\4.8.0\bin to the exe program

Then I run it again, I got:

"the application was unable to start correctly (0xc015002). Click OK to close the program.

Then I check the Event Viewer, I see this:

Activation context generation failed for "D:\rest\rrpT.exe". Dependent Assembly Microsoft.VC80.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50727.762" could not be found. Please use sxstrace.exe for detailed diagnosis.

First of all, it is very strange to me because I am building and debugging the application on VS2008 but it asks for the dll files form VS2005. Then I copied those files from VS2005:

msvcm80d.dll - msvcp80d.dll - msvcr80d.dll

to the program folder but it is still the same error :(

And I think there is also something interesting:

Activation context generation failed for "C:\Bin\QtSolutions_PropertyBrowser-2.5d.dll". Dependent Assembly Microsoft.VC80.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50727.762" could not be found. Please use sxstrace.exe for detailed diagnosis.

why is that PropertyBrowser is dependent on VS2005?

Any idea?

It sounds like your copy of Qt was compiled with VS2005, thus it probably has a dependency on the version 8 runtime DLLs. But your application is built with VS2008 and thus has a dependency on the version 9 runtime DLLs. In general, you can't get both versions of the runtime DLLs into one process. VC++ tends to break binary compatibility between major versions.

You need to recompile your own copies of the Qt DLLs with VS2008 or develop your application with VS2005.
