Can't open or run CPA on Windows 7 machine

I am unable to open CPA after inputting the location of my properties file (which is an output from a CP pipeline). Every time I’ve tried, I just get a small white box with nothing displayed, and the program then crashes. Here are the log errors from my machine:

The program cpa.exe version stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

I am running Windows 7.

@daviddao might be able to help.

Sorry about that.

  1. Which version of CPA are you using? Did you get it from the main download page or a newer build from Github?
  2. Has it run before successfully on this machine? If yes, clearing the prefs might help. On Mac it is called CellProfilerAnalystLocal.cfg and I think the same for Windows, though I don’t know offhand where it is stored.
  3. Can you upload the properties file here? Sometimes a malformed properties file can cause a crash.


Thanks for the help!


  1. I downloaded CPA from the main page (CPAnalyst_2.0_r11710).
  2. I have never successfully run it on this machine.
  3. The .properties file is attached here. (6.3 KB)

Hmm, i don’t see anything obviously amiss here. I suggest uninstalling CPA. You could either (a) reinstall and maybe it would magically work, or (b) try installing the (much!) more recent build here:

The only caveat in the recent build is that there is a little bug that forces you (on Mac at least) to click the CPA icon after launching it.
