Hm... I want to call this command line after installation:

echo hello> echo_test.txt

What should I do?

Usually, error 1721 means either problem with the script or some sort of permission issue.

Your custom action is deferred, non-impersonated action, so it runs elevated under Local System account on Vista.

Things I would check:

- MyCA.bat is runnable outside of the installer (does not have any spelling/wrong commands issues)

- Script in MyCA.bat does not access any network resources

- Just in case, run installation from command prompt which is started under Administrator privileges

- If you use Vista, try to turn off UAC

- Try to disable anti-virus software (if computer is running any)

Sorry, you will have to debug this issue. There is no definite answer for this error code.

Hi Alex,

I'm trying to get a custom action type 2 working but it keeps failing with error 1721. Do you have any idea why this is? Here is my code.

Thanks in advance.
