# Platform Notes - Windows

This page contains information about the Windows platforms Qt is currently known to run on, with links to platform-specific notes. More information about the combinations of platforms and compilers supported by Qt can be found on the Supported Platforms page.

- Windows Vista
- Windows XP, Windows 2000 and Windows NT

- Installation location
- AccelGALAXY graphic card
- Possible GL conflict

## Windows Vista

At the time Qt 4.5.3 was released, there were no known Vista-specific issues.

## Windows XP, Windows 2000 and Windows NT

### Installation location

Installing Qt into a directory with spaces, e.g. C:\Program Files, may cause linker errors like the following:

     c:\program.obj not found

Install Qt into a subdirectory without spaces to avoid this problem.

### AccelGALAXY graphic card

When you use a NT 4.0 machine with the driver number 4,00,1381,1000,021,4.0.0 there is a problem with drag an drop and icons. The computer freezes, and you have to reset. The problem disappears with the newest version of the driver, available at www.es.com.

### Possible GL conflict

There is a known issue with running Microsoft NetMeeting, Lotus SameTime and other applications that require screen grabbing while direct rendering is enabled. Other GL-applications may not work as expected, unless direct rendering is disabled.
