Hi. I am unable to install any apps on my Windows 7 laptop. No matter which app it is, if I try to run the .exe installer sitting on my hard drive, I get the following message: Error 1335. The cabinet file '<<SOME FILE>>.cab' required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package. If I press the Ignore button, I get the following: Error 2350. FDI server error I've updated the firmware on my laptop's HDD. I called Lenovo, and they said that I need to re-image the machine! But what's to say this won't happen again and again? Please tell me someone has seen this problem and fixed it... TIA Adam

I ran SFC: C:\Users\adam.weisser>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection did not find any integrity violations. C:\Users\adam.weisser> I have actually come to suspect that there is something wrong with my USB. I am able to run installs that are downloaded directly from the Internet or off CD. It's only installs copied from USB drives or USB sticks.For instance, I was able to install VMPlayer after downloading it, but the VM snapshot copied from a USB hard drive had a corrupt file. It seems that files are routinely corrupted when copied from USB drives.This is why I suspect my USB subsystem.I've recently installed the beta Windows 7 USB driver on my laptop and will see if that makes a difference next time I have access to the USB drive with the software I need on it.Thanks for your help thus far and I will post the results.CheersAdam

Hi Adam, Thank you for letting us know the additional information. It should be the USB drive problem. If the issue persists, you can post here.Vivian Xing - MSFT
