Windows 7: environment variable not working

Question

I added the environment variable "qt" with the value "C: \ qt \ 4.3.4 \ bin", and also added the path to the system variable. the path mattered below, and I added the new value "C: \ qt \ 4.3.4 \ bin" to the end. but still it doesn’t work, any idea what is the problem?

"C:\Program Files (x86)\Java\jre6\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files (x86)\IBM\RationalSDLC\ClearCase\bin;C:\Program Files (x86)\IBM\RationalSDLC\common;C:\qt\4.3.4\bin"

Answer 1

This problem occurs because windows have a length limit of 1024 or 2048 characters in the PATH variable. I wrote a small application to take care of this problem and reduce unnecessary text from the PATH environment variable in Windows 7. It simply removes duplicates and removes paths that are no longer valid.
