Help! A very irritating computer error!

[Strider]

i've been suffering for 8 months because of this error right now.
here's the error.
when i want to open my modem app.exe (the trigger to get my modem functioning, a message appeared and said :
APP.EXE - APPLICATION ERROR
(X)(a quite big X symbol here) THE APPLICATION FAILED TO INITIALIZE PROPERLY (0xc0000034). CLICK ON OK TO TERMINATE THE APPLICATION.

that's it, can't open my modem for 8 months because of this.
but, i borrowed my friend's modem(different type) and it CAN be opened from my laptop!
and when i lent my modem to my friend, it worked!
i tried system recovery, i don't have any backups for system recovery, @@
the problem all started when i downloaded KASPERSKY AntiVirus(not sure if it's an antivirus or something else but definitely kaspersky), scanned my computer, and voila, the problem came up.

could you please help me?
a help would be very, very, very, appreciated.

Go to the website of the modem manufacturer, download the drivers for your modem, and install them.

[Strider]

tried it, didn't help.
=(

If your modem works on another computer, but not yours...and a different modem works on yours, it HAS to be a driver problem.

[Strider]

oh yeah, the error is just not on my modem, yahoo messenger won't open too.

yes i think so too, i want to solve this problem if it is possible.

Try disabling Kasperky temporarily, and run the application. If the application starts, then you should add it to Kaspersky's exceptions list. Otherwise, your file might have become corrupt for some reason (maybe it was infected, and kaspersky tried to "clean" it, which would usually fail and the file will become unusable) Try uninstalling this "app.exe" application, and then installing it again (using your modem disc/floppy)

i deleted this kaspersky, lol, because it's lagging so much in my computer, and i tried install uninstall like, thirty times.
and still didn't work.

Some system files are corrupted; try to restore your system, if it didn't work, reinstall Windows!

[Muscab]

reinstall Windows!

I second this.

[Strider]

i want to try it, can you teach me how to reinstall windows by my own?
my money is a bit low, lol.

At first, copy your important information from Drive C into another Drive.
Installing Windows 7 & 8 are similar;
Insert Windows Disc into the DVD-Drive & Restart your system;
Press Enter when you see the Dos screen & Wait for the Windows to prepare setup;
Choose your Language & Keyboard and proceed to the next step;
There are two kinds of installation: Upgrade & Custom (Advanced), select Custom; Also there are two other kinds of installation (Architecture): x86 & x64 >> Select x64 if you've a 64-Bit based Processor and more than 3 GB RAM, otherwise select x86!
Select and format your System drive; then click next while the System Drive is being highlighted.
You're all done, just wait for the windows to be installed.

If you still have problems installing your Windows, feel free to tell me

Wow, okay. Lets sort this out.

You're jumping the gun; the "just reformat everything and pray" option is what lazy people do to fix simple problems. We haven't ruled out all other possible solutions, therefore there is no reason to be recommending anything so drastic just yet.

Go to the website of the modem manufacturer, download the drivers for your modem, and install them.

^this is the correct solution. However, you need to go through and uninstall the old drivers through your device manager first, as well as any applications listed under your Add/Remove Programs prompt (in the control panel) related to the modem. Restart your computer.

Now make for damned sure you downloaded the correct drivers for your modem. BEFORE attempting to reconnect it, install the drivers, restart for good measure. Finally, you can attach the modem and it "should" be working correctly.

If your modem works on another computer, but not yours...and a different modem works on yours, it HAS to be a driver problem.

^YES. This is an incredibly common issue with a very simple solution, there's no reason any experienced windows user shouldn't know to at least try this in a case like this.

"Strider" asked me to help him reinstall his windows, and I did it! suggest a solution Mr. Active!!!

oh yeah, the error is just not on my modem, yahoo messenger won't open too.

The problem is not just Modem!

[Strider]

for maslowk,
as i said,
i already did download my modem's driver, and it didn't work, 12 times to be exact.
and yes, if it is a driver problem, then can you help me with a solution?
i really really appreciate your comment though, thank you very much.

and for "naughty" boy,
i only have 2 disk drives, C and D, so you're saying i should move my important files to other drive, and that drive must be drive D right?
i'm gonna try it maybe seven days from now, hoping there are better solution than reinstalling, i don't really want the trouble with copying and moving and installing my lovely software again, lol.
thank you so much guys.

I mean you have to copy, make a backup copy from (etc.) your files to prevent them from being deleted! You can also send your files to a Flash Memory device.
I've no other idea to fix the problem, but I'm sure the problem will be solved by reinstalling windows!
Have you tried System Restore?
