I can't believe that all of these machines have the same exact problem. Even machines that were brand new and had no anti-malware software installed failed to download these files. I've attached logs from both bit and bit downloads. All of them fail in the exact same spot, no matter what machine I try to download them from. Richard V. Most Valuable Professional. On the other hand, if it was due to a server problem at the source, it should be affecting everyone's download attempts similarly.

Are those "multiple locations" served by the same ISP by any chance? Some of them do use some weird caching proxy arrangements to save bandwidth leading to some very strange results at times. Regards, Richard V. Edited 15 October PM by Arvy.

I logged into a completely different server - offsite from my work or home location. This server is using a different ISP. General cab1. Error loading cab1. Failed to register cab1. Runtime Error - cab1. The file cab1. Runtime Error! How to Fix cab1. Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred. In the search results, find and click System Restore. Follow the steps in the System Restore Wizard to choose a relevant restore point.

Restore your computer to that backup image. If the Step 1 fails to resolve the cab1. If this Step 2 fails as well, please proceed to the Step 3 below.

There are a couple of mistakes towards the end, but they don't obfuscate the brightness of this masterpiece. It helps you to develop the line of reasoning in order to extract information from problems in order to solve them.

Wishful thinking - What if the problem was solved? The book focus on teaching three things: strategies, tactics, tools.

A cryptographic hash is a checksum or digital fingerprint derived by performing a one-way hash function a mathematical operation on the data comprising a computer program or other digital files.

Any change in just one byte of the data comprising the computer program will change the hash value. The hash value is, therefore, a unique fingerprint for any program or other digital files. Ensuring that a program has not been tampered with, or just corrupted, is a fairly simple matter of calculating its hash value and then comparing it with the hash checksum provided by its developers.

If it's the same, then you have a reasonable degree of confidence that the program you have downloaded is exactly the same as the one published by its developer. If it is not, then the program has been changed in some way. The reasons for this are not always malicious see below , but a failed hash check should set alarm bells ringing. Hash checks are useful for ensuring the integrity of files, but they do not provide any kind of authentication. That is, they are good for ensuring the file or program you have matches the source, but they provide no way of verifying that the source is legitimate.

For example, fake websites exist which distribute malicious versions of popular open source software such as KeePass. Many of these websites even provide hash checksums for the programs they supply and, were you to check these against the fake program, they would match. An additional problem is that mathematical weaknesses can mean that hashes are not as secure as they should be.
