Problem:

This post is based on a troubleshooting thread found on the C3 forums here: http://customscreators.com/index.php?/topic/19095-i-really-gotta-fix-cat-now-i-cant-take-this/

CAT ran fine on Reaper x64 with 64-bit Python but on Reaper 4.22 (32bit) with Python 2.7.0 (32bit) I get this error when loading CAT:

Script execution error
  
Traceback (most recent call last):
File "CAT.py", line 3, in <module>
import create_beattrack
File "F:/CAT\create_beattrack.py", line 1, in <module>
import Tkinter
File "C:\Python27\Lib\lib-tk\Tkinter.py", line 38, in <module>
import FixTk
File "C:\Python27\Lib\lib-tk\FixTk.py", line 65, in <module>
import _tkinter
ImportError: DLL load failed: %1 is not a valid Win32 application

Reaper Configuration:

Follow these steps to check your Reaper configuration:

1. In Reaper click the Options menu, and then click Preferences.
2. In the left hand panel scroll down and select ReaScript from the list.
3. Check that the Enable check-box is checked and that python2.7.dll is installed (Figure 1).
4. Click OK.

Figure 1: Reaper Preferences for ReaScript.

Troubleshooting:

Reaper contains a custom action for CAT. If needed this action can be removed as follows:

1. In Reaper click the Actions menu, and then click Show action list.
2. In the Actions window select Custom: CAT.py and then click the Delete button (Figure 2).
3. Click OK.

Solution:

The problem is that Python x64 is still being loaded despite the fact that the 32 bit version of Python has been installed. The solution is as follows:

• Uninstall Python versions and delete the C:\Python27 folder.
• Re-install Python 2.7 (32 bit).
