I had a similar experience, I work in the office of 2010, and I want to use Office agents available before Office 2003. so I installed Excel 2003 on my mailbox and I did not work.
I found this post and tried all the options. reaseaching I found that I should use:
Set myApp = CreateObject("Excel.Application.11")
for office 2003, but it didn’t work.
All my tests were performed in VBSedit software, which shows that it used office 2003, but actually it was the opening of 2007.
I tried with primalscript
and worked like a charm.
I think this can help others.
