I have a 64 bit Windows 7 operating system,when i try to download the file it shows not a valid application. I tried installing both the packages 32 bit and 64 bit. It seems that the installer is corrupt.

Instaler is working.If u use Firefox just rename file with extension *.part ..... remove this extension and ad at least one letter in name to change enter and it will work.U will have working exe.

For users with problem related to "download completes, but installer does not run" 

If your download completes (i.e: If the browser confirms "Download Complete"), then go to the download location and located the downloaded file. Ensure that the extension of the downloaded file is .exe; if not, change the extesion and run the downloaded file again.

I am manufacturing 24V, 2.5A SMPS using lnk6666e, in some of SMPS I am facing issue where when I am power up the circuit, it doesn't give any output. But when I am switching off the input supply, it gives 24V output for 1 sec. 

Circuit diagram attached herewith.

Please provide solution.
