I have had a few things not work under run scripts "Define your own script" using %comspec% when it works perfectly fine from a command prompt.

My current issue is I cannot get it to recognize enviroment variables that do show up when you run the set command from the command prompt. Here is an example of one that fails:

msiexec /i \\Server1\Source\%AnyVariable%update.msi /qn

The file name on the source would be anyvariableupdate.msi. Again when I run this from a command prompt it works with no problems. Any ideas would be appreciated this is getting to be a real problem with our migration from ZEN 7 where these scripts worked fine.
