I uninstalled a working version of 5.2.? (don't remember which one now) and installed 5.2.39. Before I installed it i downloaded and installed both of the prerequisites (visual C++ x86 redist and .Net 4.0 client).

When I run it I get

Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 1026
Date: 2012-04-19
Time: 13:23:56
User: N/A
Computer: REDACTED
Application: MySQLWorkbench.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

at MySQL.GUI.Workbench.Program.Main(System.String[])

The program has been successfuly writing the wb.log during startup, so accessing that file isn't it. Here's the wb.log...

Suggested fix:
Hey Bryce,

since the work environment is successfully logged there must be something with your environment variables (which would be the next item to be logged). The crash happens in the logger itself so probably the string passed to it contains something weird. Can you file a bug report (http://bugs.mysql.com) and attach the output of your SET command (run this on a command line). You can make this private in the bug tracker, so your env values are kept save.

I also came across this bug. Per the suggestion at <http://forums.mysql.com/read.php?152,526320,527055#msg-527055> I removed the percent signs from environment variables names. This fixed the issue.

Fixed as of Workbench 5.2.41, and here's the changelog entry:

Using the '%' character within environment variables could cause
MySQL Workbench to crash.
