[osgeo4w-dev] OSGeo4W-setup or PC error???

[jsilva123 at sapo.pt]

Hello everyone again,

There is nobody who can help me solve this problem?



I'm starting now with the program Qgis and I have a problem, I need  
help to solve it.

I installed the 1.8.0 and 1.9.0 Qgis through Osgeo4W - Setup, the  
installation had no errors, but when I run the Qgis, the icons of the  
trunk version 1.9.0 does not appear. Show only icons of version 1.8.0  
(Lisbon).

I went to the folder where I installed Qgis (C: \ OSGeo4W \ bin), and  
have selected the icon Qgis-dev.exe and Qgis-dev-browser.exe and the  
following message appears:



"It is not possible to start the program because qgis_core.dll is  
missing on your computer. Try reinstalling the program to fix this  
problem."



I uninstalled and went back to install qgis but the error is always the same.

Someone help me find a solution to this error, please?



My OS is Windows 7 64 bit.


Thanks for the help
