Hi,

Thank you posting!

Based on my understanding, the problem is the ProductVersion's evaluation
does not work in your VS setup project's launch condition.

If so, since the ProductVersion's value is not a number, I suggest you add
the double quote mark around the specific value, for example:

ProductVersion<"1.0.9"

Thanks!

Best regards,

Gary Chang
