3rd party software vendor need copy of TestStand to troubleshoot

Hi,

I am having an intermittent problem using TestStand to access (via COM server) another software (SmartBear TestComplete). This issue appeared when we upgraded the TestComplete software version. We have exhausted all our solutions thus far and still have same issue. The software vendor request if hey can get copy of TestStand to troubleshoot on their end.  What's the best way to do this?  Are there vendor to vendor cross testing platforms?

Thanks,
