Hi forum! I recently picked up the 30 days trial version of MLwiN for my dissertation project and I consider purchasing the full license. However, so far I have not been able to make MLwiN to run with Stata 14. I have followed the tutorial (http://www.stata.com/meeting/uk11/abstr ... leckie.pdf) and used the tutorial data set and successfully created a global mlwin_path.

When I, in Stata, execute:

. runmlwin normexam cons, level2(school: cons) level1(student: cons)

MLwiN does not open and Stata gives me the error "The model did not run properly in MLwiN. You most likely clicked the 'Abort Macro' button in MLwiN, rather than the 'Resume Macro' button." The same result occurs if MLwiN already is running when I execute the command in Stata.

What do I do wrong?

Kind regards,

David

Could you try running the following command to check that the MLwiN_path global has been set correctly: When you run this MLwiN should start, if not then it would be worth checking that the value you set the global to refers to the location of MLwiN on your machine, as it is likely to be different to the one in the tutorial you refer to.

Thanks for the reply Chris! If I run shell $MLwiN_path MlwiN responds, so I guess the problem isn't related to the global... Just to clarify, is it correct that I do not have to do anything in MlwiN prior to the runmlwin command in Stata?

Yes, that is correct, it should just be a matter of telling -runmlwin- where MLwiN has been installed. It's possible that because MLwiN has been wrapped up to make it a trial version that the command line options are not being passed on correctly, however if that was the case I would have expected that at least the application would have started up. Could you try running the Stata command: and posting the output from Stata, in particular from just before the error message is displayed?

Let me know if you need more of the Stata output. Thank you once more!

Could you try the following command: and report any messages as this may help determine whether the problem is with our shell plugin? This should, like the -shell- command before, start up MLwiN.

. runmlwin_qshell $MLwiN_path
-------------------------------------------------------------------------------------------------------------------------- begin runmlwin_qshell ---
- version 9.0
- syntax [anything(equalok everything)] [, *]
- if `"`anything'"' == "" {
= if `"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Centre for MultiLevel Modelling\MLwiN 2.36 (32-bit).lnk"' == "" {
capture plugin call runmlwin_quietshell, `"cmd"'
if c(rc) == 199 {
shell `cmd'
}
}
- else {
- capture plugin call runmlwin_quietshell, `"`anything'"'
= capture plugin call runmlwin_quietshell, `"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Centre for MultiLevel Modelling\MLwiN 2.36 (32-bit
> ).lnk"'
- if c(rc) == 199 {
shell `anything'
}
- }
---------------------------------------------------------------------------------------------------------------------------- end runmlwin_qshell -

This did not start up MLwiN, however.

Could you try changing your global from the shortcut location: to the location of the executable, which will be something like:

That did solve the issue! Awesome, thank you!

Kind regards,

David
