Jaikoz- Discussion Forum

What is being suggested is that it seems likely that the Jaikoz.zip on you hard drive is not exactly the same as the Jaikoz.zip on the jthink.net web server, due to loss/dropped packets/"interference" during transmission.

The MD5 algorithm can take practically anything and convert it into a very small, but unique, string (MD5 checksum). If even one letter is wrong the checksum won't match. This is also what is widely used to secure your password when you register for websites.

Anyway, 'Anonymous' says the checksum for his copy of Jaikoz.zip is 90e633c5c61369fa4f7aa828adac168b. I checked my Jaikoz.zip and the checksum is also 90e633c5c61369fa4f7aa828adac168b. Since I can unzip my file, I will assume the Jaikoz.zip on the server also shares the same checksum.

Now, the question is, does yours?

1. If you head over to RapidCRC's website and download a copy of the "RapidCRC 0.6.1 Installer". Open this up and it will install like any other program. Let it associate itself with *.md5 files if asked.

2. I have created an MD5 checksum file (using RapidCRC). Download a copy of this file by right-clicking here and selecting "Save target as.../Save link as...". This file assumes two things, a) this file is in the same folder as Jaikoz.zip, b) the file which it is to check is called exactly "Jaikoz.zip".

3. So now you should have a Jaikoz.zip and a Jaikoz.md5 in the same folder. The *.md5 file should have a green/black ying-yang type icon. If so, double-click it. If not, right-click it and go to Send To -> RapidCRC. If you can't do either, you will have to launch RapidCRC from the Start menu, and open Jaikoz.md5 using the "Open Files" button.

4. RapidCRC will look for a file called Jaikoz.zip and check it matches our checksum. It will report one of the following in the top-right of the window.

File not found - There isn't a Jaikoz.zip in this folder.

File corrupt - Jaikoz.zip is corrupt. It isn't the same as the one on the server. Download a fresh copy and try again.

File OK - The file isn't corrupt. It is an exact copy of the one on the server. There is a conflict between the file and the unzipping program.

Error - There is something wrong with the Jaikoz.md5 file.

Tell us how you get on.

Me again, my forum account is working now.

I had accidentally cut the contents of jaikoz.bat when looking at it, hence no output. I have reinstalled and ran the tests again.

After all the above output Jaikoz launches with the same error message as shown in the initial post.
