Method1:
1. At first I removed the protection from system drive (i.e. partition in which your operating system is residing). In my case it was C:
Steps : System properties -> Advanced System Settings -> System Protection
Select System drive then click on configure, then choose option which says, turn off system protection.
2. Then I restarted the computer and hit f8 continuously to bring the startup menus (like one to start safemode in XP), from the options I choose to disable the driver signature.
3. After computer comes to working state, I installed the driver (Download Link), which I had downloaded from the cable manufacturer’s site. (For details view my previous post on vista)
4. I set the setup file in compatibility mode (For Windows XP SP2003). Then I ran the setup, which I already had extracted.
5. I got Drive Install Failure dialog box. Then I plugged the cable, windows starts to search for the drivers, I choose to manually install the driver, then I located the driver manually, and when asked choose to continue anyway with driver installation.
6. Then I tested it with HyperTerminal and also with Java Communication API, and it is working great.
Remember, You will have to disable driver signature verification every time you restart your computer, if you are willing to use USB to serial communication otherwise the drivers for HL340 cable can’t be installed, when you plug it to computer.
And the other problem I have seen so far is that, each time it is installed to computer, the PORT seems to be used and not released and thus system assigns the new address to the port i.e. each time you plug it to computer, a new address is assigned, suppose first time you plugged it, it assigns say, COM3, then when you use the cable second time, it assigns say COM4, and so on. And the total ports that can be used is upto COM255.
Let me know if you are having any problem during installation, please post error you received.
Method2:
If that doesn’t work you can try this one:
Stop the Hardware Policy Driver from. At first it is hidden, you have to enable the show hidden devices by clicking on the view > show hidden devices in device manager menu.
Then under non-plug and play devices, you will find the hardware policy driver, double-click on it, then select driver and click on stop. Under startup select demand.
Now search for another driver named Windows Firewall Authorization Driver under non-plug and play and repeat the same steps as you did for Hardware Policy Driver.
Then restart the computer by disable driver signature.
Once computer is in working state, Select the driver setup file, right-click on it, select troubleshoot compatibility, then select try recommended settings, and then click on start program. When asked to install driver select continue anyway.
This helps sometimes, I got it work twice, my luck.

Symbian goes Open Source
Now that Symbian has fully opened its source code to the public, will it lead to an avalanche of mobile operating systems opening up their codes as well?
After all, Symbian and Google's Android mobile operating system offer application developers and device manufacturers free operating systems for their products. Will this put pressure on other operating systems to open up their source codes to stay relevant?
The answer is, "Not likely." As ABI Research analyst Kevin Burden has noted, two of the most widely used mobile systems in the world -- Apple and Research in Motion's BlackBerry -- are wholly managed from within by their owners. In other words, Apple and RIM have found tremendous success with their operating systems despite the fact that they're the only device manufacturers that use them.
"The device manufacturers who have made the biggest strides in the market are the ones who own the whole solution, from the hardware to the platform to the application stores," he says. "I don't think we'll see Apple or Palm try to reverse that anytime soon."
And although Symbian is already the most widely used mobile operating system in the world, its decision to open up its source code is more likely an attempt to push back a challenge from Android than to undercut the proprietary mobile operating systems such as iPhone and BlackBerry. Android is projected to become the second-most used mobile operating system behind Symbian by the end of 2012.
IDC analyst John Delaney says that Symbian's decision to open up its source code is only one part of its effort to forge better relationships with developers that have been heavily courted by Apple and Google in recent years. And in any case, he says that Symbian's bigger draw for developers is the sheer number of users it has and not the fact that it now has an open source code.
"What developers want at the end of the day is to make money," he notes. "And that is directly related to the number of users a platform has."
So looking toward the future, it seems we can expect a mix of open source platforms and proprietary platforms, especially since both Apple and RIM have shown they can be successful without relying on third parties to develop and sell devices with their operating systems. Indeed, as Burden notes, RIM still has room to grow with its BlackBerry platform as it will start really targeting the Asian market over the next few years.
"RIM has got a lot more space to grow because they're only now getting into many parts of Asia," he says. "I don't think we've gotten to point yet where proprietary platform providers are talking about changing their strategies."
