Ok...I think I have a better idea of what you need based on the comments above.
First off, if all you need it DB2, I'd go download DB2 10.1 Express-C (the link will take you to whatever is the latest at the time. At the time of this post it is 10.1 Fix Pack 2) to get you started. It is the same binaries as Enterprise Server Edition. All you need to do is purchase a license from IBM and apply it using db2licm -a <license file name> in order to turn your Express-C into Enterprise Server Edition. Now, that aside, since you are installing this on Windows, make sure you download the appropriate bit version (ie, 32 bit vs 64 bit).
Also, and this from my experience on Windows, make sure you install the 64 bit DB2 into Program Files (no matter which drive you install it to) and if you install the 32 bit DB2, install it into Program Files (x86) (on a 64 bit OS). If you don't do this, Windows won't find the DB2 drivers for any ODBC connections you wish to set up. And even with that, I've had hit and miss luck with 32 bit DB2 on 64 bit Windows.... Best to just use 32 bit DB2 on 32 bit Windows and 64 bit DB2 on 64 bit Windows.
Ok...whew! Now that aside, once you install DB2, it will automatically create an instance named DB2 and most likely create a database called SAMPLE (which you can always remove).
I've found it best (and this is just me) to use a system or local account for the admin ID for DB2. Either way, make sure you let DB2 create the DB2ADMNS and DB2USERS groups. Anyone you want to be able to maintain DB2 will need to be in the DB2ADMNS group and obviously if you just want to access DB2 in the DB2USERS group.
DB2 automatically comes with the DB2 Control Center,which is clunky as all get out. But don't let that turn you off. That is just a GUI, the actual database itself is amazingly fast and powerful. Besides as of version 9.5 or 9.7, IBM has deprecated the Control Center. They still have packaged it with DB2, but they really recommend that you download IBM Data Studio, which is a free, Eclipse-based product that you can use to interact with DB2. I recently downloaded it and tried it. I love it waaaaay better than Control Center. We (the DBAs at our company) are going to work on a project to roll out Data Studio to replace end user and developer access to DB2 to move away from Control Center.
When you download Data Studio, pick the "full product image" under the "Optional Downloads" section. It should be the one about 1.5GB rather than the one above that is only 112MB.
Anyway, hope this gets you started. Let me know if you have other questions.
The cleanest method I can think of is to examine only one table : mysql.user
If you can login to mysql at all, run this query:
SELECT COUNT(1) column_count FROM information_schema.columns
WHERE table_schema='mysql' AND table_name='user';
Here are the answers you should get:
- If you get 43, MySQL 5.6
- If you get 42, MySQL 5.5
- If you get 39, MySQL 5.1
- If you get 37, MySQL 5.0
If you cannot login to mysql, copy the table
user.frmuser.MYDuser.MYI
to another machine running mysql.
On that other machine run CREATE DATABASE junk;
Go to the datadir in that other mysql server
Change directory to junk
Copy the three files for the user table into it. If the other machine is a Linux box, remember to run chown mysql:mysql user.*
Login to MySQL on that other machine and run
DESC junk.user;
It will tell the same numbers I mentioned before.
However, if you get 28 that's MySQL 4.1. If you get 17, that's MySQL 4.0. Have fun with that one.
Give it a Try !!!

You need to edit pg_hba.conf file in your Postgres installation, and add an entry to allow access via other machine or allow network range.
As you had success accessing Postgres on the same machine, that could be the reason. Access via localhost is default. Let us know if worked.
