In my windows 7 machine, I installed Daemon tools lite so that I can mount cd/dvd iso images. But when I add a new virtual drive in Daemon Tools, the native popup of installation of driver failer pops up in taskbar. I tried running as administrator, but no luck. Then I installed another freeware called WinCDEmu, but the same 'failed' popup comes when I try to add a virtual drive.

Is there anything fault in my registry which interrupts this driver installation?

I have install avast antivir, but I even disabled it to see whether is causes this. But results were the same.

Can anybody give me an explaination.
