Please try the workaround described in http://wb.fabforce.eu/?p=1259 and report back if it works

I tried running MySQL Workbench 5.2 CE as "administrator" and am still receiving the same error on start up.

Can you get the list of files in the WB install folder and paste to this issue?

[31 Oct 2011 15:28] Alfredo Kojima

Please try this, from a command prompt shell, go to the installation folder of WB, then (as administrator):
cd python
..\python -mcompileall ..

If that doesn't work, please report and try deleting all .pyc files in that folder manually.

The ...\python\ directory doesn't contain a python executable.  Here is what is in my python directory:

 Directory of C:\Program Files (x86)\MySQL\MySQL Workbench 5.2 CE\python

10/28/2011  12:50 PM    <DIR>          .
10/28/2011  12:50 PM    <DIR>          ..

You need to run the python command in the parent directory inside the python directory.
Type exactly:
cd python
..\python -mcompileall ..

The "..\" before python in the 2nd command is important.

Does workbench start after that?

[31 Oct 2011 20:26] Alfredo Kojima

What is the error you're getting when trying to start it?

[1 Nov 2011 11:50] Alfredo Kojima

OK, your error is actually a different one than what I thought. This is a duplicate of bug #62529

Any other suggestions as to why MySQL Workbench will not start after installing it in my Windows 7 environment?

Are you sure you installed the 32bit version of the C++ runtimes?
